How does the front thermostat work on a Duramax Diesel place?
The front thermostat controls the coolant flow to the bypass port and to the water outlet. The rear thermostat only controls the coolant flow to the water outlet. When the coolant temperature is below the rated thermostat opening temperature, the front thermostat valve remains closed to the water outlet and is opened to the bypass port.
What are the thermostats for a 6.6L diesel engine?
As the element is cooled, it contracts. This contraction allows a spring to push the valve closed. The 6.6L diesel engine requires two thermostats for correct coolant flow. The front thermostat is a dual purpose thermostat. The front thermostat controls the coolant flow to the bypass port and to the water outlet.
What’s the difference between front and rear thermostats?
The front thermostat is a dual purpose thermostat. The front thermostat controls the coolant flow to the bypass port and to the water outlet. The rear thermostat only controls the coolant flow to the water outlet.
Where does coolant go in a Duramax diesel engine?
Coolant is drawn from the radiator outlet and into the water pump inlet by the water pump. The coolant flows to the heater core while the engine is running. This provides the passenger compartment with heat and defrost. Coolant is then pumped through the water pump outlet and through the coolant pipe to the engine oil cooler.
