Forced Induction

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 Inc about any concerns you have and about the next services your vehicle needs.

Packing Bearings

save-gas-benton-harbor

 

I remember my dad having the shop “pack the bearings” on the family car. Is this something I need to have done?

That’s a really good question. At one time, all wheel bearings were “serviceable” and needed to be taken care of from time to time. It’s a little trickier these days.

First off, the wheel bearings in your vehicle make sure your wheels rotate smoothly. As you can imagine, with all those revolutions per minute your wheels can generate a lot of heat. The bearings keep that heat down as much as possible. They’re packed in grease for lubrication. The term “packing the bearings” refers to putting fresh grease around the bearings.

On many modern vehicles, the wheel bearing assembly is sealed. These wheel bearings are not serviceable so there is no maintenance that can be performed on them. When the bearings wear, the entire assembly is replaced. Your friendly and knowledgeable Pro Muffler & Brake Shop Inc technician can perform a check of your bearings to make sure they are still functioning safely, and he can also tell you if your bearings need service. If you hear strange noises from your wheels – which may come and go at different speeds – it’s time to have your friendly and knowledgeable technician inspect them.

Wheel bearings on trailers are almost always serviceable. This means anything from a monster sized fifth-wheel camper to a little utility trailer. Boat trailers are especially susceptible because the hot wheel bearings are plunged into cold water when launching a boat into the lake. This temperature difference can draw water into the bearings. Have the bearings repacked at the end of the season to prevent corrosion.

It would be a good idea for Benton Harbor trailer owners to have maintenance service on their trailer wheels every year or so – it’s kind of hard to hear when they are groaning.

Now, when wheel bearings fail, the wheel can seize up and even break off. Of course no Benton Harbor driver wants that to happen, so follow a regular inspection schedule – your friendly and knowledgeable Pro Muffler & Brake Shop Inc service advisor can help.

Save Some Gas!

save-gas-benton-harbor

 

High Michigan gas prices have hit most of our budgets here in Benton Harbor. If increased fuel costs are consuming a bigger portion of your budget, you may be tempted to skimp in some other areas – like scheduled maintenance.

According to Michigan news reports and industry studies, you’re not alone. Nine out of ten personal vehicles on the road have at least one maintenance or repair item that hasn’t been. Some of these items are serious safety concerns. Others are just more likely to affect the cost of operating your vehicle.

In this area, we can take a lesson from professional vehicle owners in the Benton Harbor area: fleet owners and operators like trucking companies and Benton Harbor delivery services. Because their livelihood depends on it, they have gotten scheduled maintenance down to a science. And the last thing they skimp on is regular maintenance.

Why is that? Well, for one thing they know that routine maintenance prevents repairs and costly breakdowns. They also know that a well-maintained vehicle uses less fuel. For them, even a small decrease in fuel economy may mean not being profitable.

Here are some services that could potentially save you some gas in Benton Harbor:

Fuel system cleaning, transmission service, differential service, wheel alignment, oil change, tune-up. Ring any bells? Is there at least one thing on the list that hasn’t been done? Let’s suppose you chose to spend $150 at Pro Muffler & Brake Shop Inc and get caught up on some of these services and that they combine to improve your fuel economy by 15 percent. What would that mean to your pocketbook?

Well, the average personal vehicle in Michigan is driven about 12,000 miles a year. If you get 20 miles per gallon, over the course of one year you would pay for the $150 worth of service and save an additional $165 if gas is $3.50 in Benton Harbor. If gas is $4.50, you would save $255. And you’d rack up savings of $345 with gas at $5.50.

From this you can see that the more fuel costs in Benton Harbor, the more it pays to take care of your vehicle. Some of us Benton Harbor drive trucks for work or recreation – or want a large SUV for family needs. A 15 percent improvement in fuel economy can generate huge savings – $660 a year if gas is $4.50 a gallon at your Benton Harbor gas station.

So catch up on those services at Pro Muffler & Brake in Benton Harbor. Talk with your friendly and knowledgeable Pro Muffler & Brake Shop Inc about your vehicle’s needs. Get a couple done now and a couple next time. Chances are you’ll save a lot of on fuel this year – and a lot more on repairs in years to come.

Ask Your Mechanic

ask-your-mechanic-benton-harbor

 

A lot of service and repair customers in Benton Harbor are a little tentative when they talk with their automotive advisors. They want to ask questions but don’t want to be embarrassed or to seem pushy. Cars are very complicated and there’s more to know about them than most of us Benton Harbor drivers have the time to learn.

At Pro Muffler & Brake, we think automotive service customers have a right to ask any question they need to understand what is wrong with their vehicle and what it will take to fix it. They need to feel free to ask the cost and benefits of recommended services. And they certainly have a right to understand the financial end of the transaction.

It’s all about the communication. What are some of the barriers to communication? Well, most Pro Muffler & Brake service advisors are very busy trying to service and fix cars to get Benton Harbor drivers back on the road. So, just ask when you feel you need more information.

Financial related issues seem to be most frustrating to Benton Harbor customers. If you’re not sure, ask what the auto repair payment policies are. For example, there’s a big difference between giving your vehicle a quick once over and doing a thorough inspection. Diagnosing a problem may take quite a while for your friendly and knowledgeable Pro Muffler & Brake technician. Make sure you know what’s done as a courtesy and what has a fee. Remember, you still have to pay for the office visit even if the doctor says you only have a cold.

Communication is a two way street. If you have some real budget concerns, ask your friendly and knowledgeable service advisor what he can do. He can give you priorities and options. He can tell you what needs to be taken care of right away for safety or financial reasons. Then you can work out a plan for when to get the rest done. He can also help you with options on the parts. The preference is to always use a high-quality part with a reputation for reliability. But if money is real tight, he might be able to find rebuilt auto parts or a used part. He should tell you the difference in the guarantee for the part so you can make a good decision.

Ask about Pro Muffler & Brake warranties for car parts and labor. Be sure to get all the paperwork you need to make a possible claim in the future. At Pro Muffler & Brake in Benton Harbor, we stand behind our work and want you to understand precisely what that means.

Be sure to ask for and keep a detailed explanation of all the work that’s done on your vehicle. These records will help you keep track of service, warranties and document the good care your vehicle has received at Pro Muffler & Brake  when the time comes to sell it.

Fuel Tip: Alignment

wheel-alignment-benton-harbor

 

Imagine you’re up in the arctic on a dog sled. Your dog team is pulling straight and true. You can cover a lot of ground fast. Now imagine what would happen if one or two of the dogs wanted to go their own way and were pulling off to the side. That would slow you down. You would have to work harder to keep the sled going where you want it. The dogs are all working as hard as before, but you’re covering less ground for the same effort. You’re wasting kibble.

The same is true of your vehicle when the wheels are out of alignment. That wheel that’s pulling to the side is dragging down the rest of the car; so you push a little harder on the gas pedal to keep up your speed on Benton Harbor roads. You’re wasting gas.

Have your wheel alignment checked at least once a year. We can help you with that at Pro Muffler & Brake Shop Inc in Benton Harbor. Get it checked right away if you feel the car pulling to one side. Sometimes we bump a curb or hit a pothole and knock our wheels out of alignment. An accident can take the wheels out of alignment as well.

So make sure you’re tracking straight in Benton Harbor. You’ll save at Benton Harbor pumps and your tires’ll last longer. Now, mush!

Dirty Battery?

dirty-battery-repair-benton-harbor

Batteries are a huge part of modern life. Think of how many battery chargers you have.

Of course, our purpose here is to talk about your car battery. When people come into Pro Muffler & Brake Shop Inc and need a new battery, they’re really not that happy about having to spend the money. But the fact is that 70 percent of batteries don’t make it for 4 years.

There are some things that you can do to extend the life of your battery. First, keep it clean. If you see it getting dirty or greasy, let us know at Pro Muffler & Brake and we can clean it off. A dirty battery runs hotter, and that shortens its life. If your battery terminals are corroded, let us take a look at that, too. We can clean them, and if the corrosion has gotten into the battery cables, we can replace them.

Also, running your battery way down is bad for it. Things like running the headlights or watching a DVD player with the car turned off can deeply deplete your battery. The typical battery can only take about 10 of those deep cycle depletions before it gives up the ghost.

Because we often take short trips around Benton Harbor with lots of stops for errands, our batteries can end up not getting fully recharged just by driving around. That also shortens battery life. You can hook up a good quality automatic battery charger at home from time to time. We recommend charging once a month during hot months and every three months during cold months.

Now when it’s finally time to get a new battery, we can help you find the right replacement. We’ll always make sure to meet your manufacturer’s recommendations. If you have special needs, like live in a very cold climate or run a lot of electrical accessories, we can look at an upgrade that’ll give you the power you need.

Water Pump

water-pump-repair-benton-harbor

The cooling system in an engine has five components: the radiator, the radiator cap, the hoses, the thermostat and the water pump. The water pump is literally the heart of the system. Just as your own heart keeps your blood circulating through your body, the water pump keeps coolant circulating through your engine.

The water pump is driven by a belt, chain or gear and only operates while the engine is running. It has a limited life span and sooner or later will have to be replaced. You can check your owner’s manual to find out how long your water pump should last. Some can fail at only 40,000 miles, or 65,000 kilometers, but almost all of them fail by 100,000 miles, or 160,000 kilometers.

Water pumps don’t gradually wear out; they fail. In other words, they’re either working or they’re not. A failed water pump has to be replaced.

Water pumps can fail in two ways: they can spring a leak or their bearings fail. Leaks can come from a cracked pump but usually develop at the gasket where the pump attaches to the engine.

If you hear a low-pitched grinding sound coming from the water pump, it’s time for a new one. If you see coolant leaking in the area near the pump, it needs to be replaced. Also, coolant on the driveway could indicate water pump failure. Many water pumps aren’t visible because they’re under a plastic cover, so you may have to take your vehicle to Pro Muffler & Brake Shop  to know if the water pump has failed.

If your water pump is run by the timing belt, then it should be replaced when you replace the belt. Most timing belts need to be replaced at around 60,000 to 90,000 miles, or 100,000 to 145,000 kilometers. The labor for replacing a timing belt is about 90% the same for replacing a water pump, so it’s cost-effective to take care of them both at the same time.

Also, if your water pump develops a leak (if it’s powered by the timing belt), you have to replace the timing belt as well since contamination by coolant fluid damages the belt. It just makes sense for Benton Harbor residents to replace both of these parts whenever either one needs it.

Replacing a water pump at Pro Muffler & Brake Shop is a vehicle care issue that almost all of us Benton Harbor residents face eventually. They don’t last forever. On the other hand, we can extend the life of most of the components of our vehicle through preventive maintenance. Just as exercise and diet keep our heart healthy, regular check-ups and fluid changes will keep our vehicles healthy. Talk to your friendly and knowledgeable Pro Muffler & Brake Shop service advisor.

Clean your EGR

new-tires-vs-old-tires

Benton Harbor drivers realize it is pretty amazing how auto makers have been able to consistently build more powerful engines in vehicles that get better fuel economy while at the same meeting increasing environmental standards. One of the little miracles that helps make this happen is the Exhaust Gas Recirculation (EGR) Valve. The EGR valve routes some exhaust back into the air intake system in both gasoline and diesel engines. The exhaust gas takes up some space in the engine cylinders, replacing some of the oxygen-rich air that would otherwise be in there. This means that the fuel burning event is cooler. Cooler combustion means fewer harmful nitrous oxides are produced.

Your EGR valve can get gummed up, messing up the timing and amount of exhaust that is supposed to be recirculated in the engine. Symptoms of EGR valve problems are rough idle and poor engine performance. Performance can be restored by cleaning or replacing the EGR valve, depending on how dirty it is.

EGR valves in diesel engines are particularly susceptible to becoming clogged because of the high soot content in diesel exhaust. (Note: the soot is ultimately filtered out of the exhaust further down the exhaust system, but not before it passes through the EGR valve.)

There are a couple of things you can do to lengthen the life of the EGR valve in your diesel engine. First, extended idling allows for more soot buildup because the engine operating temperature is reduced as it idles; the valve is not opening and closing, allowing particulates to accumulate in the valve. Next is fuel quality. Diesel fuel has a cetane rating: the higher the rating, the better the combustion will be. Unfortunately, the cetane rating is rarely posted on the pump and can vary from location to location. Adding a cetane booster to the fuel tank can help with this.

So, if you are experiencing rough idling or poor performance in your gas or diesel vehicle, have one of our Pro Muffler & Brake Shop expert technicians diagnose the problem. They can set things right and restore your vehicle’s performance.

Drum Brakes

new-tires-vs-old-tires

Drum Brakes

Brakes that work properly are essential to your safety as you drive and stop on our Benton Harbor streets. You want to carefully maintain your brakes. In vehicles equipped with drum brakes, the brake components are housed inside a drum that rotates with the wheel. When you step on the brake pedal, brake shoes push out against the inside of the drum, slowing the wheel.

Now brake shoes just wear away with use from rubbing on the drum as you brake. When it’s time to replace brake shoes, it’s a straight-forward repair.

If you hear squealing or grinding when braking, have your Pro Muffler & Brake service advisor check them out. He’ll have a technician perform a thorough brake inspection to see what needs to be done. He’ll check for signs of brake problems and go over other brake components to see that they’re working properly.

He can tell you if it’s time to replace the brake shoes or if there are other issues with your brakes that should be addressed. Some people in our Benton Harbor community ignore the warning signs and keep driving long after the shoes are completely worn out. When that happens, metal brake components will grind against the drum, damaging it enough that it has to be resurfaced or replaced.

When you push on your brake pedal, the wheel cylinder is activated and it pushes the shoes against the drum to slow the vehicle. This cylinder and various springs within the brake can wear out, affecting your ability to stop. The worn components can be easily replaced.

The new brake shoes we put on your vehicle will restore your brakes to the manufacturer’s specifications. Or we can install upgraded parts to increase your stopping power and reduce brake noise and brake dust. We have several options to meet your braking requirements and your budget.

Taking care of your brakes keeps them working safely, and you could prevent premature brake repairs down the road.

Cabin Air Filter

new-tires-vs-old-tires

Dirty Cabin Air Filter?

Let’s talk about cabin air filters. There seems to be some confusion about them in Benton Harbor that we should be able to clear up. Much of the confusion starts because cabin air filters are relatively new. Not all vehicles on the road have them, so some people confuse their cabin air filter with the engine air filter.

Every vehicle in Michigan has an engine air filter that cleans the air going into the engine, but not all have a cabin air filter that cleans the air going into the passenger compartment. Easy to get mixed up.

The cabin air filter cleans out dust, pollen, spores and other pollutants. To give a point of comparison, a grain of sand is about 200 microns across. A cabin air filter can stop particles that are just 3 microns in size. It really does make the passenger cabin a much more pleasant environment.

When the cabin air filter gets dirty, you just need to replace it. Your owner’s manual may have a recommended interval for changing it. If not we can inspect it. You know, it’s ironic that many people who don’t realize they even have a cabin air filter first find out they do when it starts to get smelly.

Some cabin air filters are very easy to access when it’s time to replace them. Others, not so much. We may have to get behind the dashboard and it takes some time.

A clean cabin air filter keeps out smog, allergens and other harmful pollutants. If it’s time, get it changed right away.
