How Does  Car Thermostat W ork Car thermostat function: The automotive Car Thermostat is a temperature controlled on and off valve. Any liquid-cooled car engine has a small device called the thermostat.Car thermostat sits between the engine and the radiator.When the temperature rises to a predetermined temperature, the thermostat opens up to allow the engine coolant to flow through the cylinder block and the radiator.  This flow is crucial to maintain optimum operating temperature for fuel efficiency, enhanced drive ability, and engine protection.You can say the thermostat reduces engine wear, deposits and emissions. See  the image shows how thermostat functions when engine is cold and when engine is hot Car Thermostat controls the engine cooling system.The coolant flow is reduced when the engine is cold, and the flow is increased when the engine is hot. Contrary to popular opinion, operating the vehicle without the thermostat doesn't make the...

Helpful Information A thermostat maintains engine temperature as it opens and closes throughout the engine operation. Once removed, inspect the condition of the main body of the thermostat, look for cracks or broken pieces and the valve to be closed. Avoid running an engine without a thermostat, this unit also acts as a system flow regulator, if coolant is allowed to travel too fast in the system, the heat exchange rate is reduced in the radiator and the engine will overheat. A thermostat consists of a main housing, a plunger valve with return spring. Temperature sensitive wax fills a plunger...

How To Replace Car Thermostat Helpful Information Like any mechanical device, over time, the thermostat can fail due to a weak spring or corrosion. If the thermostat is stuck closed, coolant cant flow which will result in engine overheating, if the thermostat is stuck in the open position, the engine will not reach operating temperatures in cold weather, passenger heater operations will also be weak. Coolant is toxic and can be fatal to animals and children so use caution when handling and be sure to recycle at a proper collection facility. Tools and Supplies Needed Screwdriver set Pliers Drain pan Socket set Gasket scraper or sand paper Coolant New thermostat and gasket Shop towel Best Practices Replace radiator hoses and clamps Flush cooling system When the system is hot it holds pressure, use caution.
