Why Is My Car’s Check Engine Light Flashing

Fri, 26 Sep 2025 13:30:11 GMT

When your check engine light turns on, it’s usually a sign that something needs attention soon. But if that light starts flashing, it’s a much more urgent problem. A flashing check engine light typically means your engine is misfiring in a way that could damage your catalytic converter or other critical parts. That’s not a warning to brush off or save for later. Here's what it really means and why you should get your car looked at right away.

What a Flashing Check Engine Light Really Means

Unlike a steady light, a flashing one signals active engine misfires. That means the fuel in one or more of the cylinders isn't burning properly. Unburned fuel can then enter the exhaust system, overheat the catalytic converter, and cause lasting damage. The more you drive in this condition, the greater the risk of serious repair costs.

This isn't a minor issue. Even if the car seems to run fine otherwise, a flashing check engine light means your vehicle is harming itself each time you hit the gas.

Common Causes of Misfires That Trigger a Flashing Light

There are several things that could cause your engine to misfire. It may take a professional diagnostic tool to know for sure, but these are some of the most common reasons:

Worn spark plugs or ignition coils

If the spark isn’t strong enough, the fuel-air mixture won't ignite properly, leading to rough running and misfires.

Fuel delivery issues

A clogged injector or failing fuel pump might not supply enough fuel to the engine, or the mixture might be too lean or too rich.

Vacuum leaks

A leak in a vacuum line can disrupt the air-fuel ratio, causing poor combustion and triggering a misfire code.

Bad sensors

A failing crankshaft or camshaft position sensor can throw off timing, which is critical for proper combustion.

Internal engine problems

Issues like low compression or valve trouble can also cause cylinders to misfire, especially in higher-mileage vehicles.

Is It Safe to Keep Driving

The short answer is no. Driving with a flashing check engine light, even for a short distance, increases the risk of severe damage. A misfiring engine runs roughly, can overheat parts of the exhaust system, and may eventually cause a breakdown. In the worst cases, this could turn into a costly catalytic converter replacement.

If you're near your home or a repair shop, it might be safe to carefully drive there. But if you're far away, the safest move is to pull over, turn the car off, and call for a tow. The potential cost of a tow is far less than replacing a damaged engine or exhaust system.

What to Do When You See a Flashing Check Engine Light

Don’t panic, but don’t ignore it either. As soon as you notice the light flashing:

Ease off the accelerator. Try not to accelerate hard, especially uphill or when passing.

If the engine is running rough or shaking, avoid further driving unless absolutely necessary.

Schedule a diagnostic scan with a qualified repair shop to identify the specific misfire code.

Get the issue fixed quickly to prevent further damage.

The longer you wait, the more likely other parts of the system will suffer damage. It's better to treat a flashing check engine light like a “do not ignore” sign for your vehicle’s health.

Diagnosing the Cause Quickly and Accurately

At a qualified repair shop, technicians use a scan tool to read the diagnostic trouble codes stored in your car’s computer. These codes will indicate which cylinder is misfiring and often point to the specific system or part that is failing. From there, a technician may perform more targeted tests, such as checking fuel pressure, inspecting spark plugs, or testing compression.

What seems like a mysterious dashboard light is actually your car giving very specific clues about where the problem lies. The key is getting the right professional help to translate those clues into action.

Can a Faulty Thermostat Cause My Car to Overheat?

Fri, 29 Aug 2025 12:45:04 GMT

Your vehicle’s thermostat may be small, but it plays a big role in regulating engine temperature. If it stops working correctly, your car can quickly overheat or run too cold, both of which can cause serious damage. Knowing how the thermostat works, the symptoms of failure, and what to do if it’s faulty can help you protect your engine and avoid costly repairs.

How the Thermostat Works in Your Cooling System

The thermostat controls the flow of coolant between your engine and radiator. When your engine is cold, the thermostat remains closed, allowing the engine to warm up quickly. Once the engine reaches the correct temperature, the thermostat opens, letting coolant flow through the radiator to prevent overheating.

If the thermostat sticks in the closed position, coolant can’t circulate properly, causing the engine temperature to rise rapidly. If it sticks open, the engine may never reach optimal temperature, leading to poor fuel efficiency and increased wear over time.

Signs of a Faulty Thermostat

A malfunctioning thermostat often shows clear warning signs:

Rapid Overheating: The most obvious sign of a stuck-closed thermostat.
Temperature Fluctuations: The gauge may swing from cold to hot without warning.
Coolant Leaks: Excess heat can create pressure that forces coolant out of hoses or the radiator cap.
Poor Cabin Heat: A stuck-open thermostat can keep the engine from producing enough heat for the heater to work properly.

How Overheating Damages Your Engine

An overheating engine can warp the cylinder head, damage the head gasket, and even seize internal components. These repairs can be far more expensive than replacing a faulty thermostat. If you notice your temperature gauge climbing quickly, it’s important to pull over safely and shut off the engine before serious damage occurs.

Diagnosing Thermostat Problems

Our technicians can test the thermostat’s operation by checking coolant temperature, inspecting flow, and, in some cases, removing the thermostat for bench testing. They will also inspect related components, such as the water pump, radiator, and hoses, to ensure there are no additional issues.

Thermostat Replacement Process

Replacing a thermostat involves draining some coolant, removing the old unit, installing a new one with the proper gasket or seal, and refilling the cooling system. The technicians will also bleed air from the system to prevent air pockets, which can cause hot spots and further overheating.

Preventing Cooling System Failures

Routine cooling system maintenance , such as flushing the coolant at recommended intervals and checking hoses, belts, and the radiator, will extend the life of your thermostat and other components. Preventive care is far less expensive than repairing damage from overheating.

Why Does My Vehicle Shake When I Drive Over 50 MPH?

Fri, 25 Jul 2025 12:45:00 GMT

A smooth, steady ride is something every driver expects when cruising down the highway. But if your vehicle starts shaking once you reach higher speeds (around 50 mph or more), it can be both annoying and concerning. While the cause might be minor in some cases, shaking at high speeds often signals underlying issues that should be addressed promptly to ensure your safety and prevent more extensive (and expensive) repairs down the line.

Common Causes of Vehicle Shaking at High Speeds

Tire Balance Issues

One of the most common culprits behind high-speed vibrations is unbalanced tires. Over time, tires can lose their balance due to normal wear, pothole impacts, or uneven tread wear. When tires aren’t properly balanced, they can create a wobble that becomes more pronounced at higher speeds.

If you notice a steering wheel that starts to shake as you accelerate past 50 mph, a tire balance check should be your first stop.

Wheel Alignment Problems

Improper wheel alignment can also cause shaking, though it's usually accompanied by other symptoms like uneven tire wear or the car pulling to one side. Misaligned wheels don’t track properly, and at highway speeds, this misalignment can lead to vibrations felt through the steering wheel or even the entire cabin.

Worn or Damaged Suspension Components

Your suspension system is designed to absorb shocks and maintain constant tire-to-road contact. Worn or damaged parts, such as ball joints, tie rods, or control arm bushings, can result in vibrations as the vehicle struggles to maintain proper stability.

Ignoring these issues can lead to compromised handling and increased tire wear.

Tire and Wheel Damage

Bent rims, out-of-round tires, or internal tire damage can also cause vibrations. Hitting a curb or a large pothole can bend the rim or damage a tire’s internal structure, leading to uneven rotation and shaking at higher speeds.

Brake System Issues

Although vibrations from brakes typically occur during braking, warped brake rotors can sometimes cause constant shaking, especially if they are severely damaged. You might feel pulsing through the steering wheel or brake pedal even when not actively braking.

Driveshaft or Axle Problems

For vehicles with rear-wheel drive or all-wheel drive, issues with the driveshaft or axle can result in shaking at higher speeds. Worn universal joints (U-joints) or CV joints can create vibrations that get worse as you accelerate.

Prompt Attention Is Needed

Ignoring vibrations at high speeds doesn’t just make for an uncomfortable drive — it can lead to dangerous situations. Vibrations can cause additional wear on tires and suspension components, potentially resulting in sudden failures.

Moreover, continued driving with unresolved issues can lead to more extensive damage, resulting in significantly increased repair costs.

How to Diagnose the Problem

Because several components can cause high-speed shaking, a professional inspection is necessary. During an evaluation, our technicians will:

Inspect tire balance and condition.
Check wheel alignment.
Examine suspension and steering parts for wear or damage.
Inspect brake components.
Evaluate driveline and axle components.

A thorough inspection ensures the correct issue is addressed, preventing guesswork and wasted money on unnecessary parts.

Preventing Future Vibrations

Many of the problems that lead to high-speed shaking can be minimized with regular maintenance .

Rotate and balance your tires at recommended intervals.
Have your wheel alignment checked regularly, especially after hitting potholes or curbs.
Replace worn suspension parts promptly.
Inspect your tires for damage or uneven wear.

These steps not only help avoid vibrations but also extend the lifespan of tires and suspension parts, improve fuel efficiency, and maintain safe handling.

6 Car A/C Issues That Can Ruin Your Summer Drives

Fri, 27 Jun 2025 14:30:17 GMT

There’s nothing quite like stepping into a cool car on a sweltering summer day unless your A/C system isn’t working the way it should. A failing air conditioner can quickly turn a pleasant drive into a sweaty, frustrating ordeal. While it may seem like the system just stopped working without warning, there are usually early signs or ongoing issues that gradually reduce its performance.

Knowing what to look out for can save you from discomfort and even prevent costly repairs down the road. Here are six common A/C problems that can spoil your summer driving experience.

Low Refrigerant Levels

The refrigerant in your A/C system is what allows it to cool air effectively. If your system is blowing warm air or takes too long to cool down, a refrigerant leak could be to blame. This is one of the most common causes of A/C issues and can result from aging components, damaged seals, or loose fittings.

Refrigerant doesn’t get used up like fuel. It should stay sealed within the system. If it’s low, there’s a leak somewhere that needs to be found and repaired before adding more refrigerant.

Compressor Failure

The compressor is the core of your A/C system and is responsible for circulating refrigerant through the evaporator and condenser. If it stops working, you’ll lose all cooling power. Compressors can fail due to age, inactivity, or contamination from a malfunctioning component.

Often, compressor failure is preceded by unusual noises, short cycling, or poor airflow. Ignoring these symptoms may lead to total failure, which is a much more expensive repair than addressing the issue early.

Electrical Problems or Faulty Relays

Your car’s A/C depends on a complex network of sensors, switches, and relays. If any of these components malfunction, the system may not engage properly or could stop working entirely. Electrical issues can be difficult to spot, especially since they often affect other systems too.

An experienced technician can perform a diagnostic scan to pinpoint faults and determine whether a relay, sensor, or control module needs replacement.

Clogged or Leaking Condenser

The condenser helps cool the refrigerant after it absorbs heat from your cabin. If the condenser is clogged with debris, damaged, or leaking, the system won’t cool efficiently. You may notice weak airflow, uneven cooling, or higher-than-usual engine temperatures since the condenser sits close to the radiator.

Regular cleaning and inspection of the condenser area, especially before summer, can prevent issues caused by road grime or minor front-end impacts.

Foul Odors From the Vents

If your car smells musty or foul when you turn on the A/C, you might have mold or mildew growing in the evaporator or cabin air filter. This typically occurs when moisture becomes trapped in the system, often due to inadequate drainage or humid weather conditions.

Replacing the cabin filter and disinfecting the system can help remove odors and improve air quality. If left unchecked, mold buildup can lead to health concerns and affect A/C performance .

Weak Airflow or Hot Spots

If the system turns on but the airflow is weak, there could be a problem with the blower motor, a clogged cabin filter, or damaged ductwork. In some cases, broken blend doors inside the HVAC system prevent cool air from being evenly distributed, resulting in hot spots inside the car.

These issues often worsen gradually, so it’s important to note any changes in airflow before they become major concerns.

Don't Sweat It—Let Mr. Best Wrench in Jacksonville, FL, Keep You Cool

A reliable air conditioning system isn’t just a luxury in the summer—it’s a necessity. If your A/C isn’t performing like it used to, now is the time to get it checked. Most problems are easier and more affordable to fix early on, and a professional inspection ensures your system is ready to take on the heat.

Call Mr. Best Wrench in Jacksonville, FL, today to schedule your A/C diagnostic. Stay cool and drive comfortably no matter how high the temperature climbs.

8 Tips to Protect Your Car From Hurricanes and Flood Damage

Fri, 30 May 2025 14:30:22 GMT

Living in a hurricane-prone area means preparing for more than just power outages and heavy rain. Your car is also at risk when storms approach. Wind, flooding, falling debris, and saltwater exposure can all cause serious damage—some of it irreversible. Fortunately, you can take steps to protect your vehicle and reduce the likelihood of expensive repairs or total loss.

Here are eight essential tips to help safeguard your car during hurricane season.

1. Park on High Ground Whenever Possible

One of the biggest threats to your vehicle during a hurricane is floodwater. Even a few inches of water can damage electronics, upholstery, and engine components. If your home is in a low-lying area, consider moving your vehicle to higher ground—such as a parking garage, public shelter area, or a friend’s property on a hill.

Avoid underground garages or areas near rivers, canals, or storm drains, as they are the first to flood during heavy rainfall.

2. Never Drive Through Flooded Roads

It can be tempting to try to drive through standing water, but it only takes about a foot of water to float a car. Even less can cause engine failure if water is sucked into the air intake. Driving through floodwater can also hide hazards like debris, open manholes, or sharp objects that can puncture your tires.

If you're caught on the road during a storm, turn around and find a safer route. Water damage from driving into floods is often not covered by insurance if it was avoidable.

3. Keep Your Fuel Tank Full

Storms often disrupt fuel deliveries and cause panic buying. Keeping your gas tank at least half full during hurricane season ensures you can evacuate quickly if needed and run your car for climate control or charging without relying on a gas station.

A full tank also reduces moisture buildup in the tank, which can happen when vehicles sit for long periods in humid conditions.

4. Disconnect the Battery if You Expect Flooding

If your car is at risk of flooding and you can't relocate it, disconnecting the battery can help protect sensitive electronics. Electrical systems are particularly vulnerable to water damage. By cutting off power, you may prevent some shorts or system failures after the water recedes.

Just be sure to follow safety precautions when disconnecting the battery, and don’t attempt this if the area is already flooding or unsafe.

5. Seal and Secure the Interior

Close all windows tightly and ensure that sunroofs, vents, and doors are fully shut. If necessary, use weatherproof tape to reinforce seals. If you're concerned about water getting inside, you can cover seats and flooring with large plastic sheets or contractor-grade garbage bags.

Also, valuable items should be removed from the vehicle and stored indoors. Documents, electronics, and emergency supplies should be taken with you if you plan to evacuate.

6. Protect the Exterior With a Car Cover

A heavy-duty, waterproof car cover can help protect your vehicle’s paint and windows from wind-blown debris, falling branches, and hail. Make sure it fits tightly and is secured with straps or bungees. Loose covers can become hazards themselves in high winds, so only use one that’s rated for storm conditions.

If you don't have a car cover, heavy blankets or mats secured with rope can provide temporary protection from flying debris.

7. Check Your Insurance Coverage

Before hurricane season starts, review your auto insurance policy to ensure it includes comprehensive coverage. This is the part of your policy that covers damage from storms, flooding, falling trees, and other non-collision events.

Keep photos of your vehicle and its condition in case you need to file a claim later. Having before-and-after images can speed up the claims process and help you receive full compensation.

8. Schedule a Post-Storm Inspection

Even if your car looks fine after a hurricane, it’s a good idea to have it inspected. Floodwater can cause hidden damage to brakes, wiring, bearings, and exhaust components. Saltwater exposure, in particular, can lead to corrosion that might not be immediately visible.

A professional inspection ensures your vehicle is safe and roadworthy before returning to normal driving.

Spring Auto Care Tips Every Florida Driver Should Know

Fri, 25 Apr 2025 15:45:06 GMT

Spring in Florida means warmer temperatures, sudden downpours, and longer days behind the wheel. While you may not deal with snow or ice like other parts of the country, your car still needs attention this time of year to stay reliable, safe, and efficient. Seasonal maintenance is about more than just comfort—it’s about keeping your vehicle in top shape as the weather shifts.

Here are the most important spring care tips that every Florida driver should keep in mind.

Wash Off the Winter Residue

Even though Florida doesn’t have snow and road salt to worry about, vehicles still collect plenty of grime, pollen, tree sap, and sand during the winter months. If you’ve spent any time near the coast or driven through muddy roads, your car may have a film of salt or debris on the undercarriage and paint.

Spring is the perfect time to give your car a thorough wash—including the underbody. Removing built-up debris not only keeps your car looking clean but also helps prevent corrosion on suspension components , brake lines, and painted surfaces.

Check Your A/C System Before the Heat Hits

You don’t want to find out your air conditioner isn’t working when it’s 90 degrees and humid. Spring is a good time to test your A/C to ensure it’s blowing cold, with consistent airflow and no strange smells. If the air isn’t cool enough or it takes too long to kick in, you could be dealing with low refrigerant, a failing compressor, or a clogged cabin air filter.

Addressing A/C issues now will help you avoid being stuck in a hot car once Florida’s summer heat kicks in.

Inspect Tires and Monitor Pressure

As the temperatures rise, so does the air pressure in your tires. It’s important to check your tire pressure in spring because warmer weather can cause pressure fluctuations that affect ride comfort, fuel efficiency, and even tire life.

You should also inspect your tires for signs of wear—like uneven tread, cracks, or low depth. With spring rains approaching, good tread depth is essential to prevent hydroplaning.

Proper tire maintenance helps with everything from safety to savings at the gas pump.

Replace Wiper Blades if They’re Streaking

Florida’s spring season often brings quick, heavy rainstorms—and visibility is everything when you’re driving through a downpour. If your wipers are streaking, chattering, or leaving areas of the windshield untouched, it’s time to replace them.

Blades wear out fast in sunny, humid climates like Florida, where the rubber dries and cracks more quickly. New wipers are inexpensive and make a big difference in driving confidence during unpredictable weather.

Check Battery Health

Heat is harder on batteries than cold weather, and Florida drivers often deal with early battery failure due to prolonged exposure to high temperatures. If your battery is more than three years old, or you’ve noticed slower starts or dimming lights, have it tested.

A simple battery check can help you avoid being stranded later. Our technicians can assess its charging capacity and let you know if it’s time for a replacement before the summer drain kicks in.

Look Over Your Belts, Hoses, and Fluids

Hot weather puts extra stress on your vehicle’s rubber components and cooling system. Check for cracks, bulges, or leaks in your belts and hoses, especially around the radiator. If your coolant level is low or looks rusty, it might be time for a flush and refill.

Your other fluids—oil, brake fluid, transmission fluid, and windshield washer fluid—should also be topped off and clean. These are easy to overlook but play a huge role in day-to-day reliability.

Keep an Emergency Kit Handy

Spring storms in Florida can be sudden and strong. It’s a smart idea to keep a small emergency kit in your vehicle, including items like a flashlight, jumper cables, a first aid kit, bottled water, and a portable phone charger. If you end up stranded due to flooding, battery failure, or debris in the road, you’ll be glad you have it.

Is Used Motor Oil Recycled or Just Thrown Away?

Fri, 28 Mar 2025 15:00:03 GMT

Every time you get an oil change, your engine gets fresh, clean oil to keep it running healthy. But have you ever wondered what happens to the old oil that gets drained out? Many drivers assume that used motor oil is simply discarded, but in reality, it’s one of the most commonly recycled automotive fluids.

Properly disposing of used motor oil is not only good for the environment, but it also allows the oil to be cleaned, refined, and reused in various ways. Let’s take a closer look at how used oil is handled and why recycling it is essential.

Why Can’t Used Motor Oil Just Be Thrown Away

Unlike other automotive fluids, motor oil doesn’t wear out—it just gets dirty. Over time, heat, metal particles, and contaminants build up in the oil, making it less effective at lubricating and protecting your engine . However, even after it has been drained from a vehicle, used motor oil can still be processed and reused.

Simply throwing away motor oil is dangerous and illegal in most places. Just one gallon of used oil can contaminate a million gallons of water, making it one of the most harmful pollutants if not handled properly. Pouring oil down a drain or onto the ground can damage ecosystems, poison wildlife, and seep into drinking water supplies.

How Is Used Motor Oil Recycled

Instead of discarding it, most repair shops and recycling centers send used motor oil through a refining process to remove contaminants and restore its usability. The process includes:

Collection – Used oil is gathered from repair shops, dealerships, and collection centers.
Filtration and Treatment – Contaminants like metal particles, sludge, and dirt are removed.
Re-Refining or Repurposing – The cleaned oil is re-refined into fresh motor oil or repurposed for other uses.

Since oil can be recycled over and over again, it reduces the need for new crude oil production and minimizes environmental waste.

What Is Used Motor Oil Turned Into

Once it has been processed, used motor oil can be repurposed in a variety of ways, including:

Re-refined into new motor oil – Many oil manufacturers use recycled oil in their products, making it just as effective as brand-new oil.
Converted into fuel – Some industrial facilities use recycled oil as an alternative energy source to power machines.
Used in lubricants and hydraulic fluids – Recycled oil can be blended into various automotive and industrial lubricants.

This process helps conserve natural resources while preventing harmful pollutants from entering the environment.

How to Make Sure Your Oil Gets Recycled

If you change your own oil at home, you can take a few simple steps to ensure it’s disposed of properly:

Store it in a sealed container – Use an old oil jug or a leak-proof plastic bottle.
Take it to a recycling center or auto shop – Many repair shops, including Mr. Best Wrench, collect used oil for proper disposal.
Never mix oil with other fluids – Contaminated oil can’t be recycled and must be disposed of as hazardous waste.

By recycling your oil instead of throwing it away, you help protect the environment and support sustainable automotive practices.

Why Is Skipping an Oil Change Bad for Your Engine?

Thu, 20 Feb 2025 13:37:53 GMT

Life gets busy, and sometimes, routine car maintenance gets pushed to the side. But if there’s one service you should never skip, it’s an oil change. Motor oil keeps everything running efficiently by reducing friction, cooling components, and preventing wear and tear. Neglecting this simple maintenance task can lead to severe engine problems, costly repairs, and even complete engine failure.

Many drivers assume they can go a little longer between oil changes without consequences, but the damage starts happening much sooner than you might think. Here’s why delaying or skipping an oil change is a risk you don’t want to take.

Oil Keeps Your Engine Lubricated

Every time you drive, your engine’s moving parts—such as pistons, valves, and camshafts—work together at incredibly high speeds. Without proper lubrication, metal parts grind against each other, creating excessive friction that leads to heat buildup and accelerated wear.

Fresh oil forms a protective barrier between these components, reducing friction and preventing premature engine damage. However, as oil ages, it loses its effectiveness. Over time, it becomes thick, dirty, and unable to provide the same level of protection, putting your engine at risk of unnecessary strain and wear.

Skipping an Oil Change

Motor oil starts out clean and free-flowing, but after thousands of miles, it collects dirt, debris, and contaminants from the engine. If you skip too many oil changes , that clean oil turns into a thick sludge that clogs passageways and prevents oil from circulating properly.

When oil flow is restricted, critical engine components are starved of lubrication, increasing the risk of overheating and mechanical failure. The longer you go without changing the oil, the more sludge builds up—eventually leading to severe blockages that can permanently damage the engine.

Old Oil

Oil doesn’t just lubricate—it also helps keep your engine cool. As it circulates, it absorbs heat from the moving parts, preventing excessive temperatures that could cause metal components to warp or fail.

When oil becomes old and degraded, it loses its ability to disperse heat effectively. This forces the engine to run hotter than normal, increasing the likelihood of overheating, head gasket failure, and other costly engine problems. If you notice your temperature gauge running higher than usual, it could be a sign that your oil is long overdue for a change.

Reduced Fuel Efficiency

A well-maintained engine runs more efficiently, but dirty oil creates resistance, making your engine work harder than it should. This extra strain forces your car to burn more fuel, leading to decreased gas mileage.

If you’ve noticed that you’re refueling more often than usual, old oil could be to blame. Keeping up with regular oil changes helps your engine operate at peak efficiency, saving you money at the pump and extending the lifespan of your vehicle.

Engine Wear and Costly Repairs

One of the biggest mistakes drivers make is assuming they can go just a little longer between oil changes without consequences. But the truth is, every extra mile driven on old oil increases the risk of long-term engine damage.

Neglecting oil changes can lead to:

Worn-out bearings and pistons
Increased carbon deposits
Internal corrosion and rust
Timing chain damage

Eventually, skipping oil changes can result in catastrophic engine failure—a repair that can cost thousands of dollars or, worse, require a complete engine replacement.

Keeping up with routine oil changes is one of the easiest ways to protect your engine and avoid expensive repairs. A quick visit to Mr. Best Wrench ensures that your car runs efficiently and reliably for years to come.
