We’re often asked questions about the
cooling system – the system that cools your engine
and keeps it at the proper operating temperature. Let’s examine
the topic in two areas: first the coolant itself and, second, the
parts that make up the cooling system.
your car or light truck is the mix of water and
circulates through the engine to draw off heat. First, you need to
have the proper amount. If you don’t have enough coolant it can’t
keep your engine cool.
You also need the
kind of coolant. Different makes of sedans and other
vehicles require different coolant formulation to
Finally, your coolant needs to be fresh. Over time and miles, the
anti-corrosion additives in the coolant are depleted and the
coolant can actually start to eat away at the cooling system
parts. Your owner’s manual and our
service adviser can help you with the
recommended coolant replacement schedule and make
sure you’re getting the right type of coolant.
Now let’s talk about the
cooling system components. These will all eventually wear
out and need to be replaced.
Starting with the
radiator, we see them coming into the shop with leaks or
clogged with deposits. Depending on the damage, we will clean,
repair or replace. We also see radiator pressure caps
that can no longer hold the proper
pressure. We recommend
replacing pressure caps when you change your coolant to avoid this
leaky water pumps and
hoses in our area that need to be replaced, too.
There’s also a part called the thermostat that
opens and closes to regulate the flow of coolant. Sometimes they
stick open or closed and the cooling system won’t work
Engine damage from overheating
can be very expensive to fix so it’s important to maintain your
cooling system properly with scheduled
coolant replacement and periodic inspections of the cooling
system. Certainly come in if you suspect a leak and have us take a
