Cooling System

Radiator Fans

radiator_fan_01

If you’re old enough, you’ve heard the term “fan belt”. Back in the day the radiator fan in your vehicle was turned by a belt driven by the engine. There are still belt driven fans – although most are now driven by the serpentine belt. But most vehicles now have electric fans that draw fresh air across the radiator to cool it.

As coolant/antifreeze circulates in the cooling system it captures heat from the engine and flows into the radiator. Air cools the radiator and the coolant in it before it flows back into the engine to pick up some more heat. Now your engine has an ideal temperature range in which it is most efficient: it shouldn’t be too hot or too cool. The electric radiator fans help maintain the ideal temperature.

A switch mounted in a cooling system passage checks the temperature of the coolant. If the coolant is at the low end of the range, the switch turns off the fan motor. When the coolant rises to a certain temperature, the switch turns on the fan. When you are running the air conditioning, the radiator fan will likely be turned on as well to help reduce the extra engine heat created by the load placed on it by the air conditioner.

A lot of vehicles will actually have two radiator fans. One or both or neither may be running at any given time depending on the conditions. When you are cruising at highway speeds, the air rushing over the radiator and around the engine will help control the heat. By contrast, stop and go driving around town doesn’t generate much natural air flow so the radiator fans will be working hard.

You may have noticed the sound of the radiator fan running after you turn your vehicle off. This keeps the engine from heating excessively after it has been run and shut off.

Now the radiator fan motors and the switch are wear items that will eventually fail. If your temperature light comes on while driving, you have a problem with the cooling system. Your service technician can inspect your entire cooling system, including the radiator fans, to determine what is causing the indicator light. Of course, servicing the cooling system as recommended will help extend the life of all the components. Ask your service advisor at Pro Muffler & Brake Shop Inc if you are due for a cooling system service.

Long Lasting Cooling System For Your Car

Our vehicles operate in a wide range of outside temperatures in Michigan. That’s why vehicle manufacturers use testing grounds from the frozen tundra to the blistering desert. Your engine coolant must be able to perform in these extreme temperatures, even if we don’t always get the extremes here.
A Long Lasting Cooling System For Benton Harbor Michigan Driving
Coolant has to move heat away from the engine to prevent costly damage. Water does a very good job of holding heat, but it freezes at thirty two degrees (Fahrenheit).
That’s why we mix anti-freeze with water – it lowers the freezing point of the coolant, and raises the boiling point as well. A fifty/fifty blend of water and antifreeze is the usual recommendation from Pro Muffler & Brake Shop.
And on top of that, coolant has to protect the components of the cooling system from corrosion. Your owners’ manual will tell you what kind of coolant you should use.
Coolant system failure is the most common mechanical problem people have. Much of that can be avoided by following factory scheduled service intervals.
Check your owner’s manual or with your service adviser. We can also conduct a cooling system inspection to look for leaks, weak hoses or bad connections.

Cooling System Service

Your car or truck’s 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 minivan engine to absorb more heat.

Auto Cooling SystemCoolant, or antifreeze, is specially formulated to keep your engine safe in a wide range of environmental and operating temperatures in Benton Harbor.

Without coolant, the minivan’s 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 at Pro Muffler & Brake Shop Inc.  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 MI cold. This is why you 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 the owner’s manual or ask your service adviser.

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 at Pro Muffler & Brake Shop Inc: 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 knowledgeable Pro Muffler & Brake Shop Inc service adviser or owner’s manual for the right kind because using the wrong coolant can void the warranty for your minivan cooling system.

Cooling System Service At Pro Muffler & Brake Shop Inc

Last week I was out running errands and my temperature warning light came on – total panic! I pulled over and my car was overheating.

Cooling System Issues

After it cooled down, I went right in to Pro Muffler and Brake Shop to have them take a look. My knowledgeable service adviser told me my water pump was leaking and needed to be replaced. He said water pumps just wear out and that you need to replace them because they pump the coolant that cools the engine.

He told me they checked out my radiator hoses, serpentine belt and tensioner and that they were OK. But I was overdue for changing my coolant – like, embarrassingly overdue. I didn’t realize there was a schedule in my minivan owner’s manual for when to change my coolant.

My service adviser said that the coolant actually becomes corrosive over time and could damage my radiator, head gaskets, intake manifold gaskets, heater core, metal cooling pipes, expansion (frost) plugs, etc. That’s why they recommend changing the fluid on schedule.

So, we replaced the coolant with the kind my minivan manufacturer recommends – I learned there are different kinds of coolant and you need to use the right one – and I was on my way. It feels good knowing my minivan cooling system is healthy and I don’t need to worry about it.
