This is the temperature the thermostat will start to open give or take 3 degrees the thermostat fully open about 15 20 degrees above its rated temperature many thermostats have a jiggle pin or check valve that allows trapped air in the cooling system to pass through the thermostat and be released from the system.

In a race car the floor opening temp of the thermostat is completely irrelevant unless you are running a very efficient and large radiator.

Or replace it if necessary. The next video gives you an idea about replacing a thermostat in a car. A thermostat stuck in the open position constantly pushes coolant into the engine and causes a lower operating temperature. Check your vehicle repair manual for the thermostat operating range and make sure you have the correct one for your application.

Modern car engines operate at a certain range of temperature for optimum performance.

The thermostat helps the engine maintain its working temperatures within this range. A car thermostat is a small device that sits between the radiator and the engine of a.

My cars temperature gauge while driving goes down to about 1 4 but then when i stop or go idle the temperature gauge slowly goes right to the middle. For most cars the normal operating engine temperature is in a range of 195 to 220 degrees fahrenheit though most dashboard temperature gauges don t show an exact temperature. Once the engine reaches its operating temperature generally about 200 degrees f 95 degrees c the thermostat opens.
