Can a water pump make your heat not work?
The auxiliary water pump moves hot water or coolant that has recently circulated through the engine block to the heater core. However, when the pump is not working, due to an electronics failure or the motor of the auxiliary pump being broken, the heater core will not be able to heat up.
How do I know if my water pump failed?
Finally, if you hear a high-pitched whining noise that comes from the front of your vehicle’s engine, it could be a sign that the water pump is dying. The water pump uses a pulley or belt in its operation, and if this pulley is too loose, it will make a whining sound that some describe as harmonic buzzing.
How does a Freightliner air conditioner system work?
Freightliner AC systems are much larger than most vehicle systems, and they use a larger condenser and an air compressor to cool the air. An evaporator is used on freightliner trucks as a heat exchange medium to move the heat generated by the system away from the air conditioning unit.
What causes a Freightliner air compressor to fail?
The reason for failure on freightliners is almost always a leak in the compressor due to a failure at the cooling line to air compressor seal. This, in turn, causes the compressor motor to continue running while coolant leaks out of the system.
What does an evaporator do on a Freightliner truck?
An evaporator is used on freightliner trucks as a heat exchange medium to move the heat generated by the system away from the air conditioning unit. The most common problem with a freightliner AC system is a leaking compressor.
Why does my Freightliner engine keep getting warm?
Freightliner trucks normally have a water temp gauge in the center of the dash-making it easy to know when your truck’s engine is warm. The reason for failure on freightliners is almost always a leak in the compressor due to a failure at the cooling line to air compressor seal.
