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

Englewood Florida drivers may wonder where the air in a vehicle's
passenger compartment comes from. Well, as your engine starts to
warm up, it also warms the coolant/antifreeze that circulates
around the engine and through the radiator. There is also a hose
that carries coolant/antifreeze from the engine to the heater core
and another that takes it back into the engine. The heater core
looks like a little radiator and lives in the air blend box behind
When you turn on the heat, air blows over the heater core, is
warmed, and comes into the cabin. Some vehicles have a heater
valve that moves coolant through the heater core when the heat is
on and bypasses the heater core when the heat is off. In other
vehicles, the temperature of the air is controlled within the air
blend box by how much air is directed over the heater core.
The engine cooling system, in a larger sense, also encompasses the
heater core. Things that adversely affect, say, your radiator will
also harm your heater core. The coolant/antifreeze contains
corrosion inhibitors that coat the surfaces inside the cooling
system, including the heater core.
When the corrosion inhibitors
are depleted, the cooling system can become corroded, filled with
contaminants and may even start to leak.
There are several signs that warn of a leaky heater core: First
you may a sweet smell from your vents. This is coolant leaking out
and getting into the air. You may even see vapor coming out the
vents and notice a film building up inside the windows. Of course,
breathing coolant vapors is bad for you.
You may also see coolant on the driveway. Depending on the design
of your vehicle, you may even get coolant leaking out into the
foot wells of the cabin.
Coolant/antifreeze leaking out through the heater core means that
the overall coolant level in the system will be low and the engine
is in danger of overheating – which is the cause of mechanical
The good news is that the things you do to protect your cooling
system also protect your heater core. Changing your
coolant/antifreeze as directed by your owner's manual or upon the
advice of your Xpertech Auto Repair Inc. service advisor will help
ensure your coolant has enough corrosion inhibitors working to
protect this system. Also, quickly repairing any leaks and
inspecting hoses for signs of internal breakdown will help keep
any from becoming an emergency.
Make sure you consult with your friendly and knowledgeable
Xpertech Auto Repair Inc. service advisor about when your cooling
system should be serviced.

Question On Your Water Pump
A NAPA SERVICE ASSISTANT ARTICLE
Xpertech Auto Repair Inc. Tech Question:
I was driving on the freeway in Florida and my vehicle engine
started to get hot. I turned off my air conditioner and was able
to drive the short distance to my meeting and then found a shop in
Englewood. It turns out that my water pump was leaking. It cost me
many hundreds of dollars to get it fixed. What could I have done
to avoid this?
Xpertech Auto Repair Inc. Answer:
This guy's story really did have a happy ending. When you continue
driving when your engine's overheating you risk a catastrophic
engine failure. It really is a good idea to pull over and let your
vehicle engine cool down before driving again. If you add water or
coolant, be sure your engine is cool or you risk serious burns.
Now there's no way for Englewood Florida drivers to know when
their water pump will fail – they just wear out. This fellow's
water pump replacement was more because his water pump is driven
by his timing belt. That requires a lot of hours to get to the
water pump and then put everything back on the engine.
A money saving tip from Xpertech Auto Repair Inc. in Englewood
FL.: if your water pump is driven by your timing belt – replace
the pump when you have your scheduled timing belt replacement.
That way most of the work is already done and you don't have to
pay for it twice.

Xpertech Auto Repair Inc. about when your timing belt should be

Your cooling system's job is to keep your vehicle engine cool
while driving around Englewood, Venice and Port Charlotte Florida.
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 engine to absorb
Coolant, or antifreeze, is specially formulated to keep your
vehicle engine safe in a wide range of environmental and operating
temperatures in Florida. Without coolant, the metal engine parts
would expand so much that the engine would seize up and stop
running. Many parts could be broken or warp so badly they would
have to be replaced. It could even be so bad that the whole engine
is ruined and has to be replaced. Also, if it's freezing outside
in Englewood, the water in your vehicle engine could freeze while
your vehicle is sitting out in the Florida cold.
This is why Englewood are wise to check coolant levels frequently
and have their vehicle cooling system inspected at Xpertech Auto
Repair Inc. for leaks. Also your vehicle has a maintenance
requirement for draining and replacing your coolant. These
recommendations can vary widely, so check your owner's manual or
ask your Englewood service advisor at Xpertech Auto Repair Inc..
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
vehicle 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; it is important that Englewood drivers 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 friendly and knowledgeable Xpertech Auto Repair
Inc. or your vehicle's owner's manual for the right kind, because
using the wrong coolant can void the warranty for your cooling
