| Heating & Cooling

Is your temp gauge on
overheat?
Is your heat not working properly on a cold day?
Your car's cooling system is critical to engine operation!
It circulates coolant through the engine, cooling the
cylinder heads and walls and providing heat for the car's
heating system. By means of a water pump, radiator (to
disperse excess heat), thermostat (to regulate
temperature), and fan (to keep radiator cool). Your car is
designed to run between 180 and 220 degrees F. If your
fuel-injected engine is too cool, it will run rich,
causing additional problems. If your engine runs too hot
or overheats, you may cause engine failure (blown head
gasket, cracked or warped heads, cracked block). Coolant
can enter the combustion chambers by means of a blown head
gasket or cracked/warped cylinder head.
Some of the symptoms may be white smoke from exhaust,
engine skip (fouling plugs with coolant), intermix of
coolant into the engine oil (characterized by milky
whitish oil on dipstick). If you suspect
any of these symptoms
your car should be be towed, not driven, to a repair
station. Further driving will cause further engine damage
or possible failure!
Heat is provided to your car's passenger compartment by
means of a heater control valve, heater core and hoses. It
is circulated and controlled by a series of ductwork and
vacuum actuator doors. A blower fan blows the heat for
even circulation.

Did You Know?
Low coolant can cause you to have little or no
heat in your car. Something as simple as a stuck
thermostat can cause overheat or engine running
too cool, depending on whether it is stuck open or
closed. |
