Car Thermostat Temperature Range

This can range between 195 degrees fahrenheit and 220ºf.

Car thermostat temperature range.

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. A thermostat stuck in the open position constantly pushes coolant into the engine and causes a lower operating temperature. When the engine is cold no coolant flows through the engine. Its job is to block the flow of coolant to the radiator until the engine has warmed up.

Most vehicle engines operate at a temperature range of approximately 195 220 ºf 91 104 ºc. A car thermostat is a small device that sits between the radiator and the engine of a. The next video gives you an idea about replacing a thermostat in a car. Your thermostat will typically be wide open when the temp reaches 20 degrees above the rating.

Whatever the rating is that is the temperature the wax will begin to melt and your thermostat will open. Watch this video as barry wilson explains the importance of choosing the correct thermostat for a classic car or truck engine. That s like driving with the choke on all the time the engine won t run right you ll pollute the air your gas mileage will suck. If the temperature gauge is staying the normal range.

Check your vehicle repair manual for the thermostat operating range and make sure you have the correct one for your application. 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. In a race car the floor opening temp of the thermostat is completely irrelevant unless you are running a very efficient and large radiator. Once the engine reaches its operating temperature generally about 200 degrees f 95 degrees c the thermostat opens.

Low temperature reading and underheated engine. Modern car engines operate at a certain range of temperature for optimum performance. 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. Without a thermostat your engine won t get to the operating temperature the computer is looking for so it will think the engine is cold and enrich the fuel mixture to help warm the engine.

The thermostat in most cars is about 2 inches 5 cm in diameter. It means coolant isn t entering the engine because the thermostat is stuck closed and your car can suffer engine damage fast. Or replace it if necessary. The thermostat helps the engine maintain its working temperatures within this range.
