How does Truck heat work?
How does Truck heat work?
The warmth from the engine goes from the radiator to the heater core, which basically acts as a heat exchanger. It allows coolant to flow through, and this flow of coolant is regulated by the heater control valve. As the engine’s heat is carried by coolant into the heater core, the device starts to get warm.
Where does the cool water that leaves the radiator go next?
After doing its thing, the coolant flows through the upper hose to the radiator where it releases the heat. Then, the water pump sends it back down into the engine’s water jackets to continue the cooling process.
How to troubleshoot a / C problems in Freightliner Trucks?
A specially trained mechanic should fix any problems with the AC system, but you can troubleshoot to verify that there is a problem. Turn the engine on and allow the truck to warm up to its normal operating temperature. The water temperature gauge needle should sit in the center of the upper and lower marks on the gauge.
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.
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.
