Thermostat

Thermostat

The thermostat is an important part of your cooling system. Your vehicle’s thermostat performs a similar function to the thermostat in your home. At home, you set your thermostat to maintain a comfortable temperature range. When your home gets too hot, the air conditioning kicks on and when it gets too cool, the heater turns on.

Now your engine also has an optimal temperature range: warm enough to run efficiently and not so hot as to cause engine damage. Your vehicle’s thermostat is a valve between the engine and the radiator. When you first start a cold engine, the valve (thermostat) is closed, allowing the coolant surrounding the engine to warm up to the proper operating temperature. As the coolant gets hotter, the thermostat opens, allowing coolant to flow through to the radiator to be cooled. The thermostat opens and closes to keep the engine within a certain temperature range.

Now thermostats are rated for a specific temperature depending on the engine – not a one size fits all proposition. Thermostats are subject to normal wear. Proper operation depends on a special wax that expands as it heats up to open a spring-loaded valve. A worn thermostat could stick in the open position causing the engine to run too cool. This is inefficient and could hurt performance and fuel economy. If a thermostat sticks in the closed position, the engine can quickly overheat, possibly causing damage.

There isn’t a specific maintenance routine for the thermostat, but maintaining your cooling system by changing your coolant/antifreeze on schedule will make sure the coolant has enough corrosion inhibitors to protect the thermostat and other vital system components. Cooling system experts recommend replacing your thermostat when you do a coolant flush or exchange. Also, thermostats usually wear out faster than your hoses, so if you need to replace worn hoses, replace the thermostat at the same time.

If your temperature warning light comes on, have your cooling system inspected right away. This could be a thermostat problem. The thermostat could also be the culprit if you aren’t getting hot air when you turn on your heater.

The thermostat is a relatively inexpensive part that stands guard between you and catastrophic engine damage. Follow your owner’s manual instructions, or check with your service advisor to see if it’s time for a cooling system inspection or service.

Water Pump

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.

Engine Air Filter

save-gas-benton-harbor

 

Engine Air Filter

Today we want to talk about your engine air filter.

That’s the filter that cleans the air before it’s burned in your engine. Many people in Benton Harbor wonder how often they should change their engine air filter. The simple answer is “when it’s dirty.” That’s a function of how much air has passed through the filter, so your vehicle manufacturer will recommend a mileage interval for replacing the air filter. But you can imagine that how dirty the air is would affect how quickly the filter gets filled.

If you drive in Benton Harbor where there’s lots of dust, pollution or pollen, your engine air filter will get dirty more quickly and need to be changed sooner. That’s why we check the air filter with every full-service oil change at Pro Muffler & Brake Shop Inc. We can visually tell if the filter needs to be changed.

Your filter can only hold so much dirt. Once the filter is full, dirt will pass through to the engine. This dirt gums up the combustion chamber, hurts fuel economy and may cause damage. It can also contaminate the Mass Air Flow Sensor which will affect drivability and can be fairly expensive to replace.

A dirty air filter would also restrict the amount of air that gets to the engine, which hurts fuel economy. We can replace your engine air filter with one that matches the factory specifications or you can upgrade your filter for enhanced performance.

So when your Benton Harbor, Michigan, service advisor at Pro Muffler & Brake Shop Inc shows you your dirty air filter, you know how important it is to get it replaced.

Exhaust Systems

exhaust_system_01

We’ve all heard a car or truck in our Benton Harbor neighborhoods that needs a new muffler. But there’s more to the exhaust system than just the muffler.

The exhaust system has three main functions:

  • To safely get hot exhaust gas from the engine out the tailpipe
  • Treats the exhaust to remove harmful pollutants
  • Muffle the engine noise

Exhaust gas is poisonous. You don’t want it getting into the passenger compartment. For example, carbon monoxide can be deadly. That’s why you should never run your engine in a closed garage. If you have a leak in the exhaust system, exhaust could get into the passenger cabin and make you sick or even kill you.

If you smell exhaust in the vehicle, roll down your windows and get it inspected. You may smell or see exhaust coming from the engine compartment or under the vehicle if you have a leak. Sometimes the sound from an exhaust leak is loud and obvious. Sometimes it’s a ticking sound when you start the engine that goes away as you drive. That could be a small crack or a bad fitting that leaks when it’s cold but seals up when the metal heats and expands.

Now, let’s address the environmental issues for our Benton Harbor community. Exhaust gas contains a number of pollutants and particulates. The catalytic converter scrubs some of those harmful substances. And diesel vehicles have systems to deal with soot.

Catalytic converters eventually wear out and need to be replaced. They’re expensive so you want to help them last as long as possible by keeping the fuel system clean and replacing your air filter. These components need to be tested for function with an emissions test from time to time.

And that leaves the muffler. The beauty of getting a new muffler is that you can suit your taste: Some want whisper quiet and others like a little rumble. And some like a roar when they drive down our Benton Harbor streets.

Engine Air Filter

Simple Answers from Pro Muffler & Brake Shop: Engine Air Filter:
What’s the harm in putting off replacing my engine air filter a little longer? My car failed its emissions test – what do I need to do?

Pro Muffler & Brake Shop Answer:
That’s a fair question from Benton Harbor auto owners because the harm takes a while to manifest. Let’s take a small step back and talk about what an engine air filter does.

The air all around us contains dust, dirt, pollen, spores, etc. Some areas and times of the year have more contaminants in the air. The job of the air filter is to keep that stuff out of your engine. The benefit to Benton Harbor motorists is obvious.

Now your engine uses a lot of air – like 12,000 gallons of air for every gallon of fuel – so the engine air filter hasa vital job to do. When the filter gets full and can’t hold any more dirt, all that air still has to get to the engine so dirt gets forced through the filter and heads on downstream.

The air flows passed the mass air flow (MAF) sensor on its way to the engine. The MAF sensor tells the engine control computer how much air is coming so the computer can send the proper amount of fuel into the engine to maintain the correct air-to-fuel ratio.

When dirty air is flowing passed the filter, harmful dirt starts to build up on the delicate MAF sensor elements causing incorrect air flow readings. The computer then sends the wrong amount of fuel to the engine. This can rob power from the engine. But the harm comes from unburned fuel passing out through the exhaust system and getting caught in the catalytic converter leading to expensive damage.

A primary cause of catalytic converter failure is improper engine management, often triggered by a dirty MAF sensor which was contaminated because the engine air filter had not been replaced as recommended. Now Benton Harbor car owners can buy several cases of engine air filters for what it would cost to replace a catalytic converter. So when it’s time to replace your engine filter keep in mind the potential long term effects of putting it off. Talk to your friendly & knowledgeable Pro Muffler & Brake Shop service professional.

Changing Your Engine Air Filter

Your auto engine really needs clean air to operate efficiently: it takes about twelve thousand gallons of air to burn a gallon of gas in your engine. And clean air is much better than dirty.Dirty Air Filter Pro Muffler and Brake

When your air filter’s dirty, it simply can’t trap any more dirt, so the dirt just passes through into your air intake system. From there it can get into the engine combustion chamber. And burning dust and pollen in your engine as you drive does you no good. Continue reading

Replace Your Engine Air Filter

It’s something we all know – your auto engine needs clean air to burn the fuel – and it needs a lot. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas.

All that air passes through a filter that catches the dust and dirt. Eventually the filter gets completely full. Because the filter can only hold so much, dirt starts getting through. This dirty air passes through the mass airflow sensor, and starts to accumulate on the delicate sensor element. The mass air flow sensor measures how much air is getting into your engine. When the airflow reading is incorrect, your auto engine doesn’t get the proper amount of fuel. It runs rough and doesn’t perform as well as it should.

Benton Harbor Car AdviceEventually, the sensor is so damaged it needs to be replaced – which is pricy. In fact you could buy a case or two of air filters for the cost of a sensor replacement.

Of course, that dirty air keeps on going through to your auto engine where it’s burned along with the fuel, which dirties up your combustion chamber and increases harmful exhaust emissions – not a good thing for Benton Harbor air quality, not to mention our lungs.

When your  service adviser brings out your dirty air filter and recommends a replacement, remember the cost and poor performance that can be waiting for you down the road if you neglect this simple service. Ask us if it’s time to replace your engine air filter.
