Your radiator protects your engine and air
conditioning condenser from overheating. It also plays an
important role with the computer controlled system. An
engine temperature sensor actually tells the computer what
the engine temperature is so the computer can adjust the air
and fuel mixture and engine timing. The efficiency of the
radiator directly effects the efficiency of your engine.
That's why flushing the cooling system and
pH balancing the coolant is recommended at least once every
Our coolant system power flush continuously
forces fluid under pressure through the engine, radiator and
heater core in both directions at different times to remove
contaminates. We pressure test the cooling system for leaks,
clean the recovery bottle and pressure test the radiator
cap. The system is then refilled with the proper mix of
coolant and water to reach the -35 degrees for winter
We only use new coolant and not the recycled

TWO WAYS TO SCHEDULE
We’re often asked questions in
Willoughby Hills OH 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.
The coolant in
you sedan is the mix of water and antifreeze that
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 right
kind of coolant. Different makes of sedans and other
vehicles require different coolant formulation to protect
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 your Willoughby Hills Auto Repair
service adviser in Willoughby Hills OH 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
We see leaky water pumps
and hoses in Willoughby Hills 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
Willoughby Hills car owners who are old enough have probably 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 Willoughby Hills motorists now have electric fans
that transfer 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 brings it 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
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 Willoughby Ohio car owners’ 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
Willoughby highway speeds, the air rushing over the radiator and
around the engine will help control the heat. By contrast, stop and
go driving around Willoughby Hills doesn’t generate much natural air
flow so the radiator fans will be working hard.
Some Willoughby Hills drivers may experience the sound of the
radiator fan running after turning the 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 vital wear items that
will eventually fail. If your temperature light comes on while
driving, you have a cooling system issue. Your caring Willoughby
Hills Auto Repair tech can review 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 Willoughby Hills Auto Repair technician if you are due for a
cooling system service.
My water pump went out and it cost much more to replace than ones
I’ve had replaced in the past. My Willoughby Ohio mechanic said it’s
because of where it’s located. Why is that?
Willoughby Hills Auto Repair Answer:
Some water pumps are driven by the serpentine belt and are bolted on
out in the open with the alternator and air compressor and such.
Other water pumps are driven by the timing belt. These water pumps
take a lot of labor to access and replace. I suspect your current
vehicle has a water pump that is driven by the timing belt.
Water pumps are fairly uncomplicated devices that circulate engine
coolant/antifreeze around the engine and out to the radiator. Like
any mechanical device, they eventually wear out. Although having a cooling
system service done
on schedule at Willoughby Hills Auto Repair in Willoughby Hills will
extend the life of your water pump and its seals and gaskets – it
will eventually fail and need to be replaced.
Those water pumps that are driven by the timing belt (the belt that
controls when your engine intake and exhaust valves open) are
attached directly to the engine block. The timing belt system has an
important protective cover. The serpentine belt and all the
accessories are located over the timing belt cover. So getting to
the water pump requires the service specialist remove a lot of parts
– which then need to be replaced.
When the water pump must be replaced, it is a quick idea for
Northeast Ohio car owners to go ahead and also replace the timing
belt, timing belt tensioner and idler pulleys. First, because the
timing belt may have been contaminated by leaking coolant; second,
there is a schedule for replacing your timing belt and Willoughby
car owners might as well make the modest additional added
expenditure while everything is taken apart to avoid the same labor
cost down the road.
By the way, the reverse is true as well: When you are replacing your
timing belt on schedule go ahead and replace the water pump at the
same time. It would be a shame to spend the money on one of these
replacements only to have to do it all again in a few months because
the other then needs replacement. Do them at the same time and start
the clock over for both.
