Time to Take Another Look at Diesels?

steering

 

If you haven’t looked into diesel engines lately, you may be interested in today’s post. Why should you care about modern diesel engines? Fuel efficiency, for starters. Because diesel fuel has a higher compression rate than gasoline, it generates more power per barrel. This is especially advantageous for drivers who pull heavy loads with powerful trucks that are always thirsty.

There are still many misconceptions about diesel powered vehicles. Let’s debunk some of the myths.

1. Diesel Burns Dirty
This was true years ago. Since 2006, however, U.S. diesel vehicles have been required by law to use ultra-low-sulfur diesel or USLD. Modern diesels are soot-free and have a smaller carbon footprint.

2. Diesels Are Sluggish
Not any more. They are as fast off the line as similar gasoline-powered cars. If your idea of fun is to spend an afternoon test-driving new cars, go take a spin in a diesel BMW or Porsche.

3. Diesels Are Loud
Back in the day, you could hear a diesel motor from a mile away. Today’s diesels run quiet.

4. Diesels Have a Bad Resale Value
Actually, diesel vehicles have a lower depreciation rate.

Diesel engines require parts that are heavier and stronger. At Pro Muffler & Brake Shop Inc, we occasionally service diesel cars and trucks with over 300,000 miles/500,000 kilometers. The heavy-duty parts make diesel vehicles a little more expensive new, but due to the extra burliness, diesel engines last a lot longer. This is one of the reasons Cummins diesels inspire such a loyal following.

Another often-overlooked benefit is lower risk of fire. Diesel fuel is less flammable and won’t explode like gasoline.

What about the drawbacks? Cold weather starting is one. Diesel engines can be hard to fire up when the temperature drops. However, an engine block heater can solve this problem. Talk to your friendly and knowledgeable pros at Pro Muffler & Brake Shop Inc for more .

If you are in the market for a new vehicle that’s easy on fuel, you might want to explore your diesel options. You may even qualify for a tax credit if you buy a clean diesel vehicle. Of course, diesels require regular maintenance like any other vehicle and the services are usually a little more costly due to the nature of the engines. But the extra cost is offset by the better fuel economy and longer engine life.

Bottom line? Today’s diesel is not your grandfather’s diesel.

OEM or Aftermarket

steering

 

It happens – a part on your vehicle breaks or just wears out. The replacement part is very important. You want it to last and perform like new. That’s why your NAPA AutoCare Center uses quality NAPA replacement parts. The parts we install on your vehicle will meet or exceed the specifications of the original parts.

Let’s break that down. “Meets” means that the new parts will perform the same as the parts they’re replacing. “Or exceeds” means that sometimes, the replacement parts improve on the original part.

A replacement part choice may be tailored to your preferences. Let’s take brake pads for example. Perhaps you value quiet brakes. Someone else prefers high-performance stopping power, or minimal brake dust accumulating on their wheels. Your service advisor can help you select brake pads that best meet your needs.

There are hundreds of thousands of auto parts needed to service all the vehicles on the road – including yours. Your NAPA AutoCare Center will install the right parts for your vehicle. They also provide a nationwide parts and labor warranty – ask your service advisor for details.

Forced Induction

steering

 

Most Benton Harbor residents associate turbochargers and superchargers with hot rods and racing. However, the number of everyday cars and trucks coming to Benton Harbor from the factory with chargers is growing every year. Here’s why.

You need three elements for combustion: fuel, oxygen and ignition (spark plug in gasoline engines and compression in diesels). Superchargers and turbochargers deal with the oxygen part of the formula. In the normally aspirated engines Benton Harbor residents are familiar with, air is just drawn in from the outside by vacuum pressure created as the engine runs. Turbochargers and superchargers compress the air that goes into the engine’s combustion chamber, forcing in more oxygen. This forced charge of air allows an engine to make more power than a similarly-sized, normally aspirated engine.

So today we have small 4-cylinder turbocharged engines on Benton Harbor streets making more power than a full-sized V8 did 20 years ago – and getting far better fuel economy. And the power on turbocharged six and eight cylinder engines is through the roof.

In addition to power and fuel economy, charged engines deliver benefits for Benton Harbor drivers at higher altitudes. As the air thins with an increase in elevation, there is less oxygen available to burn in the engine, resulting in a significant power loss. Charging forces more air – and oxygen – into the engine, preserving much of the power at altitude. Turbochargers use exhaust from the engine to spin an impeller that compresses the air sent to the engine. Because there is a short time between when you step on the accelerator and the time the exhaust pressure builds up enough to spin the turbo up to speed, there is a short lag in power. To combat this “turbo lag,” some use two turbos: a small one that quickly spins up when engine speed is low and a larger one for when the engine is running . Others use a variable vane technology in the impeller to accomplish the same thing.

Superchargers are driven by a belt connected to the engine’s crankshaft. There is no lag because charging starts immediately (it doesn’t have to wait for exhaust pressure). Superchargers are less efficient for Benton Harbor residents because they require engine power to run the compressor, whereas turbochargers are powered by “free” exhaust. In both types, the air heats up as it is compressed. In some engines it is necessary to cool the air before it goes into the engine. In those engines, the air passes through what is called an intercooler to bring its temperature down to the proper range. An intercooler is like a small radiator and may be cooled by air flow or by liquid coolant.

Benton Harbor owners of superchargers and turbochargers should always use the fuel grade recommended by their vehicle manufacturer. This is important in charged engines because of the extra pressure as the fuel and air is compressed. Using fuel with too low of an octane rating could lead to premature detonation which can cause damage.

Generally speaking, turbochargers and superchargers do not require regular maintenance. But they do wear like any other part in your vehicle and will eventually need repair or replacement. All of your regular vehicle maintenance should be done on schedule – things like oil changes and transmission service and so on. Talk with your friendly and knowledgeable Pro Muffler & Brake Shop about any concerns you have and about the next services your vehicle needs.

Coolant Replacement

coolant-replacement

 

Coolant Replacement 

Your cooling system’s job is to keep your engine cool. Coolant (also called antifreeze) mixed with water flows through your engine and absorbs heat. The mixture then flows out to the radiator where it’s cooled by air flowing over the radiator. From there the cooled mix circulates back through the engine to absorb more heat.

Coolant, or antifreeze, is specially formulated to keep your engine safe in a wide range of environmental and operating temperatures.

Without coolant, the metal engine parts would expand so much that the engine would seize up and stop running. Expensive parts could be broken or warp so badly they would have to be replaced. It could even be so bad that the whole engine is ruined and has to be replaced.

Also, if it’s freezing outside, the water in your engine could freeze while your vehicle is sitting out in the cold.

Therefore, check coolant levels frequently and have your cooling system inspected for leaks. Also, your manufacturer has a maintenance requirement for draining and replacing your coolant. These recommendations can vary widely, so check your owner’s manual or ask your service advisor.

The reason you need to change the coolant is that it has additives in it to protect the cooling system. As you can imagine, with all the heat, the cooling system’s a pretty harsh environment. The additives keep the fluid from becoming corrosive and damaging the radiator and other cooling system components. Over time, the additives are depleted, and the coolant just has to be replaced. A simple Ph test can measure the coolant’s acidity.

You may have noticed that there are different colors of antifreeze: it is very important that you use the correct type. The different coolant types are different colors, so you don’t mix them up. Manufacturers use different materials to make the cooling system, and they require different types of antifreeze to protect them.

So, check with your service advisor or owner’s manual for the right kind because using the wrong coolant can void the warranty for your cooling system.

Prevent Costly Repairs

Prevent Costly Repairs 

You’ve probably seen auto parts delivery trucks in Benton Harbor making their rounds. Every part has a story behind it. Unfortunately, some of the stories are tales of repairs that could have been prevented.

One stop may be to deliver an engine air filter and a mass air flow sensor for a customer’s pick-up. His service advisor has been recommending he replace that dirty air filter for the last couple of oil changes. The guy’s been saying no to save a couple of bucks. Now dirty air has been getting into his mass air flow sensor for so long that it’s ruined. Talk about stepping over dollars to pick up a dime.

Perhaps the next stop is for a fuel system cleaning kit and a set of four fuel injectors. This nice lady has never had her fuel system cleaned. Over the years, gum and varnish have completely ruined her fuel injectors. Her tech will replace the injectors and clean the system, removing carbon deposits from her valves and combustion chamber. Her engine will be making more power and getting much better fuel economy. Just too bad she had the unnecessary expense of new fuel injectors.

The next stop is a crying shame: transmission fluid and a transmission rebuild kit. When you think of a transmission rebuild you probably picture a lot of expensive broken parts. Sure, that can happen, but most of the time it’s just replacing all of these little seals and gaskets that got chewed up by dirty transmission fluid. Really, the guy didn’t service his transmission so all those little bits or dirt and clutch material that naturally come loose over the miles turn the transmission fluid into liquid sandpaper – and it just tears up the rubber seals and paper gaskets. Pretty soon there are all these internal leaks and then there isn’t enough hydraulic pressure to shift properly. Taking out, tearing down, and rebuilding a transmission can cost thousands – all because the transmission fluid wasn’t changed on schedule.

Next time you see an auto parts delivery truck around Benton Harbor, think about your own preventive maintenance. Check your owner’s manual or ask your Pro Muffler & Brake Shop Inc service advisor about your manufacturer recommended service schedule today.

Improved Fuel Economy?

save-gas-benton-harbor

 

Will Proper Auto Maintenance at Pro Muffler & Brake Shop Inc Really Save Gas?

Have you ever thought about all the little things we do to keep our lives running smoothly – like vacuuming? It makes a room feel fresher and more comfortable. We may not consider that we’re also prolonging the life of the carpet by keeping it clean. But Benton Harbor drivers don’t always extend those good habits into the garage. Our vehicles need regular maintenance just like our rugs need vacuuming. We may not notice a difference in the feel or appearance of the vehicle, but just as cleaning a carpet carries the hidden reward of prolonging its life, maintaining our vehicles incurs a hidden reward that becomes noticeable at Benton Harbor gas stations.

When it comes to reduced fuel economy, there are two culprits: increased friction and inefficient fuel combustion. That means that anything Benton Harbor drivers can do to decrease friction and increase the efficiency of their engines will translate to savings on fuel. Friction increases the amount of energy it takes to move something. So if we can reduce friction, we can decrease the amount of fuel it takes to run our vehicles. Engine oil is usually at the heart of friction problems in an engine. Too little oil means parts are not getting lubricated, which increases friction and dirty oil doesn’t lubricate as well as clean oil. So one secret to good fuel economy is to stay on top of oil changes. Don’t skip them and don’t procrastinate. The same auto advice applies to transmission fluid. Keep it full and keep it clean, and your vehicle will run with less friction and better .

If your tires are under-inflated, it increases the friction between the tire and the road. Again, there is increased drag, and it takes more fuel to move your vehicle. People in Benton Harbor should check their tire pressure every month and keep their tires properly inflated.

Alignment and brake problems can also increase friction. Besides saving fuel, keeping these systems in good repair has the added benefit of saving you on tires and brake pads. These items wear out more quickly when the alignment is off or when the brake system isn’t in good working order. Talk to your friendly and knowledgeable Pro Muffler & Brake service advisor.

The second culprit that stealthily steals our fuel economy is inefficient fuel combustion, which depends on the engine getting the right amount of clean fuel to the right place with the right pressure at the right time in the right pattern. The key to peak engine performance is to keep the fuel system clean. Varnish and gum can build up in a fuel system, which will interfere with the fuel injectors. The fuel injectors are responsible for all those “rights” we spoke of. If they’re dirty, amounts, timing, pressure and spray patterns can all get out of whack. The result? Reduced fuel economy. A fuel system cleaning at Pro Muffler & Brake Shop Inc in Benton Harbor can get your injectors back on track, improving performance and efficiency.

There are a few other maintenance items that can improve your fuel economy. One is to replace your PCV valve when it gets sticky. This valve allows unburned fuel in your engine exhaust to return to the engine. Benton Harbor can also replace worn spark plugs and dirty fuel filters. A well-maintained vehicle will require fewer repairs and save money at Benton Harbor gas pumps.

Spark Plugs

save-gas-benton-harbor

 

Spark Plugs

In Benton Harbor, Michigan, the days when Benton Harbor drivers changed their spark plugs every couple of years has ended. Back in the day, spark plugs really did wear out that often. A couple of things are different now…

First, spark plugs are made of better materials that last longer for Benton Harbor drivers and they’re designed better. The second reason spark plugs used to have to be changed in vehicles and other autos was that they were fouled up with carbon deposits. The deposits built up when fuel wasn’t burned completely. With modern engine management controls that just doesn’t happen as often.

Engine control computers precisely time when fuel is injected into the engine and when spark plugs fire. Unless something’s wrong, spark plugs just don’t foul like they used to.

Electricity from the battery goes into a coil that allows power to build up to anywhere from 12,000 to 45,000 volts, depending on the vehicle. The engine management computer tells the coil when to release the power to the spark plug. The electricity travels through a wire from the coil to the spark plug. At the tip of the plug, a spark jumps between two electrodes and ignites the gas in the combustion chamber.

Some engines have more than one coil. Coils wear out and need to be replaced occasionally. Also, spark plug wires can wear out and need to be replaced.

Modern engines used around Benton Harbor are delivering more power and better fuel economy all the time. That’s largely credited to fast engine control computers, advanced sensors, electronic ignition and improvements to the lowly spark plug.

It’ll be interesting to see where future developments take us. One last thought: it’s to have the right kind of spark plug for your vehicle. Because engines are designed to run with different internal temperatures, spark plugs have different designs to work properly within those temperatures. Your Benton Harbor, Michigan, service advisor at Pro Muffler & Brake Shop Inc will be able to get the right plugs for your vehicle. And he’ll be able to advise you on when you should replace your spark plugs as well.

Oil Change

save-gas-benton-harbor

 

Oil Change

An oil change at your local Benton Harbor, Michigan, auto shop sounds simple, but there are some pretty important things to know about preventing oil sludge.

Oil eventually starts to turn into jelly, literally: petroleum jelly. Sludge clogs up oil passages and keeps oil from getting to some areas of the engine, causing parts to wear out prematurely. And that means expensive engine repairs.

That’s why you need to change the oil and oil filter on schedule — to get the old oil out before it turns to sludge. Your manufacturer will have a recommendation for how many miles/kilometers you can go between oil changes. They also usually have a number of months between recommended oil changes. That’s because the detergents and other additives in the oil break down over time.

Your owner’s manual will have a recommendation for time and distance, but you need to remember that it’s based on using the recommended weight of oil. And if your vehicle came from the factory with synthetic oil, the recommended intervals assume you will continue to use synthetic.

Also, how you drive around Benton Harbor, Michigan, can have a big effect. Most owner’s manuals will have a list of driving conditions that are harder on your vehicle — things like stop and go driving in Benton Harbor, short trips to Benton Harbor, driving in very hot or very cold weather, heavy loads and towing. If some of your driving fits this, you may need to change your oil and do other maintenance on a shorter schedule.

This may sound complicated. Some vehicles in Michigan have an oil life calculator that takes all of these factors into account and tells you when you should change your oil. Otherwise, talk with your Michigan service advisor at Pro Muffler & Brake Shop Inc about how you drive and get his or her recommendation for when to take care of your service.

Finally, if any of the steering or suspension parts can be lubed, your technician at Pro Muffler & Brake Shop Inc will take care of that with a lube, oil and filter service.

Guide for buying a Used Vehilcle

save-gas-benton-harbor

 

The Pro Muffler & Brake Shop Inc Guide to Buying a Used Vehicle

Used vehicles are certainly an economical choice for budget-conscious Benton Harbor drivers. But how can we know we’re getting a good used vehicle and not just inheriting someone else’s problems?

There are good used vehicles for sale in the Benton Harbor area. Cars are sold when families upsize, when families downsize or even when someone just wants a new car. So the used vehicle may be just fine. But some Benton Harbor used car owners sell vehicles because they don’t want to deal with developing or existing problems.

When you’re considering buying a used vehicle in Benton Harbor, ask for service records. Check to see if the recommended schedules for preventive maintenance have been followed. If so, you probably have a great used vehicle on your hands. If there aren’t any service records, then assume the worst.

Check the vehicle for obvious signs of problems. Kick the tires if you want to, but definitely check them for uneven tread wear. This can indicate alignment problems, worn shocks or suspension issues. Listen to the engine for unusual sounds and pay attention to unexpected odors. Take the vehicle for a test drive and make a list of any concerns you might have.

If the used vehicle you’re looking at is a late model vehicle with under 35,000 miles, or 55,000 kilometers, on it, take it to Pro Muffler & Brake Shop Inc for a full-service oil change. This inspection will reveal many basic or developing problems. Talk to your friendly and knowledgeable Pro Muffler & Brake Shop Inc service advisor about concerns you had on the test drive. Get a heads-up on needed repairs or maintenance.

Previously leased vehicles are often tempting to used vehicle buyers because they are generally newer models with low mileage and have been factory-cleaned. Be cautious, however. Many Benton Harbor drivers of lease vehicles don’t bother with preventive maintenance because they know they’ll be turning the vehicles in. Again, ask for maintenance records, take the vehicle in for a full-service oil change and consult with your friendly and knowledgeable pros at Pro Muffler & Brake Shop Inc about any problems the vehicle may have.

Older used vehicles are even more problematic for Benton Harbor used car buyers. Older vehicles simply come with more maintenance and repair issues than new ones. Take these vehicles in for a used vehicle inspection at Pro Muffler & Brake Shop Inc. Usually, a seller will let you do this before you purchase the vehicle. These inspections are very thorough and will help you know what you’re getting into. You’ll be able to make an informed decision about your purchase. That peace of mind will make the cost of the inspection more than worth your while. It’s always good auto advice for Benton Harbor drivers to purchase a Carfax report on any used vehicle. This report will let you know if the vehicle has been in a major accident and will give you a title history. You’d be surprised what used vehicle buyers have learned from those reports. Know before you buy.

Once you purchase a used vehicle, give it some tender loving car care. Give it a thorough cleaning, inside and out — and don’t forget the engine compartment. A good wax will make it look and feel “new.” And, of course, stay on top of preventive maintenance. Used vehicles bought in Michigan can last a good, long time if they’re properly cared for. They’re economical to buy, and they can keep on saving us Benton Harbor drivers money if we look after them.

Water Pump

save-gas-benton-harbor

 

Water Pump

Let’s talk water pumps for autos in Benton Harbor, Michigan. The engine is cooled by coolant/antifreeze mixed with water. This mixture circulates around the engine, absorbing some of the heat. The coolant then flows through the radiator where air cools it down for the return trip back through the engine. Your vehicle’s water pump is what drives this process.

Cooling system problems are the number-one mechanical failure in Benton Harbor. So the water pump plays a pretty important role. You can’t get very far in Michigan without a water pump.

After all that distant and years of pumping coolant, water pumps just wear out. You might notice a whining or grinding sound coming from the water pump. Or maybe see coolant leaking from the pump itself.

The precise location of the water pump varies depending on the vehicle. Some have the water pump attached to the outside of the engine where you can see it. With these, the water pump is driven by the serpentine belt.

Some have the water pump driven by the timing belt. The timing belt cover often hides the water pump with this setup, so you can’t see the pump without removing the cover.

When you have Pro Muffler & Brake Shop Inc replace the water pump on one of these, you really should replace the timing belt at the same time. We’ve already gotten things taken apart and besides, the belt’s likely been contaminated by coolant. And timing belts usually need to be replaced at similar intervals anyway, so it just makes sense to do both jobs at once.

The opposite is true too; when you change the timing belt on this type of engine, replace the water pump while you’re at it. The water pump will eventually fail and getting to it is an expensive project. For not that much more you can take care of both the timing belt and the water pump at the same time.
