Replacing Your Catalytic Converter

The catalytic converter, a vital component of your vehicle’s exhaust system, plays a crucial role in reducing harmful emissions. Over time, however, wear and tear can compromise its efficiency, affecting both your car’s performance and the environment. In this blog, we’ll explore the signs and factors that indicate it might be time to consider replacing it.

1. Check Engine Light Activation: One of the earliest indicators of catalytic converter issues is the illumination of the check engine light on your dashboard. While this light can signal various issues, a diagnostic scan can pinpoint whether the catalytic converter is the culprit. Ignoring this warning can lead to more significant problems and decreased fuel efficiency.
2. Reduced Performance and Efficiency: A failing catalytic converter can negatively impact your vehicle’s overall performance. If you notice a significant decrease in acceleration, sluggishness, or a drop in fuel efficiency, it’s advisable to have it inspected. Addressing issues early can prevent further damage and enhance your car’s overall drivability.
3. Unusual Noises: Unusual sounds emanating from the exhaust system, such as rattling, hissing, or metallic noises, can be indicative of a failing catalytic converter. Internal components may break down or become dislodged over time, causing these abnormal sounds. If you hear anything out of the ordinary, a prompt inspection is warranted.
4. Failed Emissions Test: During routine emissions testing, a malfunctioning one may lead to test failures. If your vehicle consistently fails emissions tests, even after necessary repairs, it’s a clear sign that the catalytic converter may need replacement. Compliance with emissions standards is not only necessary for the environment but also for legal reasons.
5. Unpleasant Odors: A faulty catalytic converter can result in the emission of unpleasant odors, often described as a sulfur-like or rotten egg smell. This indicates that the converter is not effectively converting hydrogen sulfide in the exhaust gases. Any noticeable change in your vehicle’s emissions should be promptly addressed.
6. Overheating Issues: Catalytic converters can overheat due to engine misfires, rich fuel mixtures, or other malfunctions. If you experience overheating issues or notice excessive heat emanating from the  area, it’s crucial to investigate the root cause promptly. Overheating can lead to internal damage and compromise the converter’s efficiency.
7. Age and Mileage Considerations: While there is no set expiration date for catalytic converters, age and mileage can influence their performance. As a general guideline, converters may start to show signs of wear after 100,000 miles or more. Regular inspections, especially as your vehicle ages, can help catch potential issues before they escalate.
8. Physical Damage: External factors such as road debris, collisions, or impacts can cause physical damage to the catalytic converter. Visible dents, punctures, or a compromised housing can affect its effectiveness. If you notice any visible damage, it’s crucial to address it promptly to prevent further deterioration.

Replacing a catalytic converter is a significant decision, but understanding the signs of its deterioration can save you from more extensive and expensive repairs down the road. Regular maintenance, prompt attention to warning signs, and compliance with emissions standards contribute not only to the longevity of your vehicle but also to a healthier environment. If you observe any of the mentioned signs, consult with a qualified mechanic to assess the condition of your catalytic converter and explore appropriate replacement options.

Problems When Buying a Pre-Owned Dodge Charger

The Dodge Charger is one of today’s most popular full-size sedans. Many drivers in North Carolina love its muscle-bound styling and great everyday comfort. This car also has the potential to deliver an exciting performance, especially models equipped with a Hemi V8 engine. However, be sure to watch out for these problems when buying a pre-owned Charger. 

Avoid the 2.7-liter, V6 Engine

Dodge previously offered the 2006-2010 Charger with a smaller 2.7-liter, V6 engine. Unfortunately, this engine didn’t pack a lot of muscle. Even worse, it had a reputation for being unreliable. 

The 2.7-liter Chrysler engine was well known for oil sludge problems. Because sludge thickens the motor oil, an excessive amount of friction and heated is created. This can ultimately lead to premature engine failure. A more dependable 3.5-liter, Pentastar V6 engine was introduced during the 2011 model year. 

Transmission Trouble

Some Charger models come equipped with an eight-speed automatic transmission. This transmission’s quick-shifting nature appeals to many drivers. The bad news is that some owners report performance issues. Shuddering when changing gears, hesitation, and slippage rank among the most common problems. 

To prevent trouble in the long-run, the best approach is to have the car professionally inspected by an experienced mechanic beforehand. Often times, transmission problems stem from a lack of routine servicing. It’s extremely important to have the transmission fluid and filter changed at the recommended intervals. 

Poorly Designed Electronic Gear Shifter

In 2012, Dodge equipped the Charger with a new electronic gear shifter. While this innovative shifter freed up more space in the front, it was a bit confusing to use. Because of the shifter’s complicated operation, some drivers unintentionally failed to put the car into park. There were quite a few roll-away accidents caused by this problem. 

Dodge was eventually forced to issue a recall. Luckily, the Dodge Charger reverted to a traditional gear shifter in 2015. 

Leaky Water Pump

The water pump is one of the most critical parts on a vehicle. It’s responsible for circulating coolant throughout the entire engine. Older Charger models came equipped from the factory with a water pump that was prone to leaking. 

If the problem isn’t addressed in a timely manner, the coolant level will eventually drop to an excessively low level. Engine overheating then becomes a real possibility. The only way to solve the problem is to install an upgraded water pump. 

Non-Functioning Power Windows

Before purchasing a pre-owned Dodge Charger, don’t forget to check the condition of its power windows. They can stop working anywhere between 20,000 and 180,000 miles. 

In many instances, the problem stems from a burned-out window motor. You could also be dealing with a failed window regulator, which tends to be even more expensive to replace. 

Abuse & Neglected Maintenance 

If you decide to purchase a high-performance Dodge Charger model, it’s even more important to get a pre-purchase inspection. Some owners have a habit of pushing their car to its limits. This means parts are more likely to wear out sooner than usual. 

You should also look for a Dodge Charger that was properly maintained. When it comes to buying a pre-owned vehicle, service records are worth their weight in gold. 

5 Common and Potentially Costly Oil Change Mistakes

As a car owner in North Carolina, you probably already recognize the significance of changing your oil on time. This critical maintenance item can dramatically impact engine performance and longevity. When servicing is needed, it’s always a good idea to take your vehicle to a certified professional. Here are five common and potentially costly oil change mistakes. 

Using the Wrong Type of Motor Oil

When performing an oil change, it’s critical to always use the correct type of motor oil for your specific engine. Unfortunately, far too many quick-lube service centers fail to do so. This can lead to a number of problems in the long run. 

If the oil is too thin, this can cause the engine to experience premature wear. Leaks are also far more likely to develop. On the other hand, excessively thick oil may not flow well during cold weather. As your engine ages, it may actually do better using a different oil viscosity than when new. An experienced mechanic can determine which grade is best. 

Improper Drain Plug Installation

Your oil pan’s drain plug needs to be properly torqued. Overtightening this bolt can result in slow leaks. Too much force may also damage the plug’s threads. 

If the drain plug’s gasket is made of copper or cheap plastic, it needs to be replaced at every oil change. Fortunately, this part typically costs only a dollar or two. When the gasket becomes deformed, it’s unable to properly seal. It’s only a matter of time before a leak arises. 

Not Adding the Right Amount of Oil

It’s important to add the proper amount of motor oil. Overfilling when performing an oil change tends to be the biggest problem. This floods the crankshaft, thus causing the oil to be whipped into a foam. The end result is an inequality lubricated engine. Oil pressure can reach dangerously low levels. 

There are a few telltale signs the oil level is too high. For starters, you may notice the smell of burning motor oil. Blue exhaust smoke is yet another big symptom. Keep in mind that overflowing oil can also find its way into spark plugs, which ultimately impacts performance. At this point, you’ll likely have trouble even cranking the engine. 

Forgetting to Reset the Oil Change Light 

Many modern vehicles are designed with an oil life monitoring system. It uses special sensors to collect important data. Engine temperature, trip durations, and driving habits are just a few of the key factors that are taken into account. When an oil change is deemed necessary, the system will trigger a warning light. 

Unfortunately, some shops forget to reset the oil change light after servicing the vehicle. This is a major inconvenience. 

Forgot to Put the Engine Oil Fill Cap Back On

When rushing to finish an oil change, neglectful technicians may forget to reinstall the engine oil fill cap. This is a big problem, to say the least. The entire engine bay and hood could be covered in oil. 

Even worse, dust and debris have an opportunity to enter the engine. These particles can grind between the cylinder walls and pistons, thus causing the parts to prematurely degrade over time. 

How to Preserve the Reliability of Your BMW 3 Series

The 3 Series is one of BMW’s most popular car models. This small luxury sedan’s sporty driving dynamics and quality interior help make it an appealing choice. While the 3 Series can last for upwards of 250,000 miles with no catastrophic mechanical issues, owners must have it serviced at the recommended intervals. Here are a few important tips to keep your BMW 3 Series performing at its best.

Always Use High-Quality Motor Oil
To no surprise, mechanics stress the importance of getting regular oil changes. This is one of the biggest keys to long-term durability. If you neglect having the oil changed on time, expect the engine to experience accelerated wear and tear.

It’s just as critical to choose the correct type of motor oil. If your 3 Series was built in the past 20 years, experts advise the use of fully synthetic BMW LongLife-01 engine oil. Not only is this oil formulated to provide enhanced protection, but it also promotes better fuel efficiency.

Invest in Genuine OEM Parts
If you own a 3 Series, don’t be a cheapskate when it comes time to replace components. While aftermarket parts from China are far less expensive, they may cause you trouble in the long run. There’s a good chance your car’s reliability will be severely compromised.

The best approach is to invest in genuine BMW parts. They are engineered to fit precisely and last longer. In the event that you decide to sell or trade in your 3 Series, the installation of OEM parts will boost the car’s value.

Replace the Spark Plugs
Spark plugs have a direct impact on engine performance. When they begin to wear out, your vehicle’s drivability will take a big hit. Some of the tell-tale symptoms include rough idling, sluggish acceleration, and difficult starting. Driving with bad spark plugs can also cause other costly components to fail, including the catalytic converter.

Most BMW manuals suggest replacing the spark plugs every 45,000 to 60,000 miles. However, this interval can vary from one model year to the next. Ideally, you should have the entire ignition system periodically inspected by a certified automotive mechanic.

Shy Away from Aftermarket Modifications
At some point, you could be be tempted to make modifications to your vehicle. Unfortunately, this is often a recipe for disaster. While it’s okay to install a different set of wheels, think twice before attempting to modify the car’s powertrain or suspension. For instance, some 3 Series owners in Asheville have opted to install a bigger turbocharger. The extra load subjects the engine to significantly greater stress, thus shortening its life.

If you’re a driving enthusiast who desires peak performance, purchase a 3 Series model that already comes equipped with performance upgrades from the factory. BMW’s available M Sport package includes a lowered performance suspension and beefier brakes.

Don’t Forget About the Transmission
Like the engine, the transmission needs to be properly maintained. It’s critical to have the transmission fluid changed at the recommended interval. Fresh fluid will help keep friction to a minimum, which ultimately enhances the gearbox’s durability.

When it’s time to have the transmission fluid changed, your mechanic will also install a new transmission filter. Most filters begin to become dirty after around 50,000 miles.

Engine Repair

When engine problems occur, this can dramatically impact the performance of your vehicle. In some instances, you will ultimately be left stranded along the side of the road. Here’s a look at the six most common reasons for engine repair.

Overheating
If your vehicle’s temperature gauge begins to approach the red zone, there’s a good chance the engine is overheating. Excessive temperatures can cause several parts to be destroyed, including the head gasket and pistons. The total cost of engine repair could be thousands of dollars.

In many instances, overheating stems from a low coolant level. Old radiator hoses are especially prone to bursting during the summer. A malfunction cooling fan and a bad water pump can also cause overheating to occur.

Misfiring
A misfiring engine will cause your car to perform poorly. Some of the symptoms include rough idling, sluggish acceleration, and hard starting. Don’t be surprised if your check engine light turns on as well.

From bad spark plugs to contaminated fuel, a wide range of different issues can cause misfiring. The best approach is to have the vehicle checked out by an experienced Piedmont Triad mechanic. By performing a diagnostic test, they can quickly track down the root of your trouble.

Oil Leaks
If you begin to notice oil stains on your driveway, be sure to have your vehicle inspected by a professional. Until the necessary repairs are made, you’ll need to check the oil level more often than usual.

Fortunately, oil leaks don’t always require major engine repair. After a vehicle surpasses the 80,000-mile mark, it’s not uncommon for the valve cover gasket to deteriorate. You could also be dealing with a warped oil drain plug, which can easily be replaced with a new one.

Engine Noise
Engine noise should never be ignored. Strange sounds will often warn you of a developing problem. While the issue could be minor, the best approach is to err of the side of caution.

Of the potential noises you may hear, knocking is by far the most serious. This indicates the fuel isn’t burning properly within the cylinders. Waiting to get engine repair is not an option. Some of the likely causes include a bad knock sensor, carbon deposits in the combustion chamber, and improper spark plugs.

Car Stalling
When you’re driving with a near-empty gas tank, your car could suddenly stall at any given moment. Every year, thousands of motorists run out of gas. However, this isn’t the only thing that can cause stalling.

A failing alternator will eventually cause your vehicle to quit. When this problem occurs, your battery warning light should appear on the dash. If you begin to hear a whining sound coming from the fuel tank or experience engine sputtering, fuel pump failure is a strong possibility.

Smoky Exhaust
A well-tuned engine should not produce any visible smoke. When you start to see smoke coming out of the exhaust, engine repair could be needed. While blue exhaust smoke indicates burning oil, black exhaust smoke points to an improper fuel/air mixture.

Thick, white exhaust smoke is just as serious. Coolant is likely being burned in the engine. Your vehicle could have a blown head gasket or a cracked intake manifold gasket.
