Car radiator thermostat. With an overheating engine problem it s a good idea to have an assistant behind the wheel to shut off the engine if the temperature reaches an unsafe level while testing. In most cars the thermostat is placed under a housing near the water pump on the cylinder head. Temperature on off differential range 5º. Then start the car and let it warm up to operating temperature.

A car thermostat is a small device that sits between the radiator and the engine of a liquid cooled car. This is a small device that is located somewhere between the radiator and the engine. A thermostat to control temperature by varying the amount of coolant going to the radiator. Any liquid cooled car engine has a small device called the thermostat that sits between the engine and the radiator the thermostat in most cars is about 2 inches 5 cm in diameter.

Its job is to block the flow of coolant to the radiator until the engine has warmed up. A fan to draw cool air through the radiator. Operating range 5ºc to 120ºc. In a few cars the thermostat is housed near the bottom hose.

The probe can even be clipped directly to your radiator fins. The radiator transfers the heat from the fluid inside to the air outside thereby cooling the fluid which in turn cools the engine.

Put your hand on the radiator or top hose keep clear of the fan. The other way to tell if your thermostat is opening is to remove the radiator cap before starting the car and with the engine cold. Its principal function is to regulate the flow of engine coolant from the engine to the radiator.
