What is the Temperature this part will hold?
Sharonda G January 16, 2018
It holds right at 86 cent. Just make sure you get the clip back on and in place if not it the radiator hose pop out this product cured our heating problem.
Terry A January 16, 2018
This part is made the withhold whatever the engine is producing. However this part controls the temperature of the motor, so it wouldn’t overheat. This part opens at 90 degrees F allowing the circulation of the coolant, so motor wouldn’t overheat. Thanks
