Westgate High-Tech Auto Care Tech Question
On Your Cooling System
Westgate High-Tech Auto Care Tech Question:
I was driving down the freeway in Omaha and smoke started
coming out of my car. I pulled over and called my husband. I
had to be towed to my Omaha mechanic. He said my car had
overheated. What can I do to prevent that in the future?
Westgate High-Tech Auto Care Answer:
Oh, sounds like a rough experience. Unfortunately
overheating is the most common engine failure in Omaha .
It's also one of the easiest to prevent.
The basic idea is this: you need to keep enough
coolant/antifreeze flowing through your vehicle engine to
keep it cool. Problems come for Omaha drivers when they
develop leaks in their systems – like in the radiator or a
hose – and the coolant leaks out. Sometimes the coolant gets
so contaminated that it blocks up the radiator so the
coolant can't get through. Enough of that and you end up
broken down on the side of the road.
Your owner's manual recommends a schedule for coolant
replacement. That's because your coolant actually becomes
corrosive over time and starts to eat away at the cooling
system, causing leaks or blockages. New coolant stops that

parts, have it done right away at Westgate High-Tech Auto
Care in Omaha. Prevention at Westgate High-Tech Auto Care is
thermostat is part of your cooling system. Omaha residents'
vehicle thermostats perform a similar function to the thermostats
in their homes. 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
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 Omaha residents 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 affect performance and
fuel economy. If a thermostat sticks in the closed position, the
engine can be subject to the results of overheating.
There isn't a specific routine for Omaha residents to maintain
their thermostat, but maintaining the cooling system by changing
the coolant/antifreeze on schedule will make sure the coolant has
enough corrosion inhibitors to protect the thermostat and other
system components. Cooling system experts and the team at Westgate
High-Tech Auto Care in Omaha recommend replacing your thermostat
when you do a coolant flush or exchange. Also, thermostats usually
wear out faster than your hoses, so if a worn hose replacement is
performed, replace the thermostat at the same time.
If your temperature warning light comes on, have an inspection of
your cooling system right away. This could be a thermostat . The
thermostat could also be the culprit for Omaha residents who
aren't getting hot air when they turn on their 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 friendly and knowledgeable
Westgate High-Tech Auto Care service advisor to see if it's time
for a cooling system inspection or service.
Simple Answers from Westgate
High-Tech Auto Care for Omaha: Water Pump
Simple Answers Service Intervals
My water pump went out and it costs much more to
replace than ones I've had replaced in the past. My
Omaha technician said it's because of where it's
located. Why is that?
Westgate High-Tech Auto Care 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 simple 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 Westgate
High-Tech Auto Care 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 a
protective cover. The serpentine belt and all the
accessories are located over the timing belt cover.
So getting to the water pump requires removing a lot
of parts which then need to be replaced.
When the water pump must be replaced at Westgate
High-Tech Auto Care in Omaha, it is a good idea 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 you might as well make the
modest additional added expenditure while everything
is taken apart to avoid the same labor cost down the
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
