What happens to the thermostat when the engine is running?
What happens to the thermostat when the engine is running?
Under high loads, they will run at or above the thermostat’s fully open temperature – in other words, under hard driving, the thermostat’s opening temperature is completely irrelevant. The thermostat can only determine when the cooling system is allowed to start cooling the engine.
What to do when your engine thermostat is stuck?
When an engine is cold, the thermostat should be closed, thus bypassing the radiator. Warm (not hot!) engine test: Open hood and remove radiator cap. Start engine. Observe coolant action. It should be swirling vigorously. When an engine is warm, the thermostat is in the open position.
What happens to the thermostat during hard driving?
Under high loads, they will run at or above the thermostat’s fully open temperature – in other words, under hard driving, the thermostat’s opening temperature is completely irrelevant. The thermostat can only determine when the cooling system is allowed to start cooling the engine. It sets a floor, not a ceiling on engine temperatures.
What happens if you run a 160 thermostat?
If you run a 160 thermostat and the engine runs over that……you have NO thermostat, in effect. The coolant is circulating back and forth between the engine and the radiator and does NOT have time enough in the radiator to cool down.
Why is the thermostat open when the engine is running?
The cooling system and load on the engine determines how hot the engine gets, the thermostat fully open will still be the mercy of the coolant system’s ability to remove heat. Most engines run slightly above the thermostat’s minimum opening temperature under normal loads.
Under high loads, they will run at or above the thermostat’s fully open temperature – in other words, under hard driving, the thermostat’s opening temperature is completely irrelevant. The thermostat can only determine when the cooling system is allowed to start cooling the engine. It sets a floor, not a ceiling on engine temperatures.
Can a car run at a low temp with a low thermostat?
Once you’re moving, on the highway, with a 160 degree thermostat on a cooler day you could be cruising at 160-180 degrees (opening temp->designed operating temp). This is possible because the load on the engine is low and the outside temps are low.
Is the opening temperature of the thermostat irrelevant?
Most engines run slightly above the thermostat’s minimum opening temperature under normal loads. Under high loads, they will run at or above the thermostat’s fully open temperature – in other words, under hard driving, the thermostat’s opening temperature is completely irrelevant.
