en the thermostat doesn't open it cant let the fluids flow into your engine causing it to overheat.
If it's stuck open-nothing. If it's stuck closed (more likely) no circulation & overheating. At least they are cheap.
Energy can enter or exist an open system
The Jiggle pin allowes any trapped air behind the thermostat to pass through. Without this the engine could overheat. The thermostat uses engin coolant to melt a wax capsule and allow coolant to pass. The engin could be at operating temp and the thermostat would not open due to air being in contact with the capsule instead of the actual coolent. This would most likely lead to an overheating engin, and damage.
the air in a fridge when you open the door gets hotter because you let the particles out
The coolant is pumped from the thermostat housing into the top of the radiator but not until the thermostat opens.
It will probably overheat. answer= thermostat will not open and will prevent the flow of coolant . which will in turn do damage to your engine
If it's stuck open, no heat. If it's stuck closed, over heat.
When the thermostat in your car fails it usually fails to open which in turn does not allow radiator water to pass through the engine and cool it, so the engine over heats.
Sounds like your thermostat is stuck open. Replace that and see what happens.
If the thermostat in a vehicle sticks open the engine will not reach proper operating temperature. The open thermostat will prevent the car's heater from giving much or any heat during cold winter driving and will also cause the engine to use more fuel than normal.
If the thermostat is open, the ohm reading will be O/L.
If it's stuck open-nothing. If it's stuck closed (more likely) no circulation & overheating. At least they are cheap.
The thermostat is done it has to be replaced.......
The thermostat is in the radiator. Open the radiator lid and pull the thermostat out.
The thermostat that open at 195 F.
The thermostat is probably stuck open, even when the engine is cold.
Usually the car would run cool, unless the thermostat is stuck partially open.
