Engine Coolant Thermostat (100 Deg) by Genuine Mercedes

Engine Coolant Thermostat (100 Deg) by Genuine Mercedes

Your engine coolant thermostat sits between the engine and the radiator, in a thermostat housing. The thermostat blocks the flow of coolant to the radiator until the engine has warmed up. Once the engine is warm enough, usually around 200-220 degrees F, the thermostat opens and allows the coolant to flow. The engine coolant thermostat is the most common component of the cooling system to fail, which can cause your car to overheat in the unlikely event it were to be stuck closed. More commonly, the thermostat can be stuck open, making it difficult for your engine to warm up. This can result in your car running cool, causing an overly rich fuel mixture and an inefficient running engine. It should be replaced anytime you have major work done to the coolant system.

About Genuine Mercedes

Genuine Mercedes Logo

Founded by automotive giants Gottlieb Daimler, Karl Benz, and Wilhelm Maybach, Mercedes Benz has long been regarded as the world's oldest and best recognized automobile manufacturer. The auspicious three pointed star symbolizing dominance over land, sea and air was a portent of Mercedes Benz's sweeping success as an automotive manufacturer.

A pioneer of safety and performance features, Mercedes Benz introduced direct gas injection in the 1954 300sl, first produced crumple zones in 1959, anti-lock brakes in the w116 6.9 and incorporated airbags into production w126 sedans in 1979. With the introduction of the 560SEL, 560SL and 560SEC in 1985 and subsequent release of the ultra-luxurious w140 s500 and s600 sedans and coupes Mercedes Benz secured itself as an immutable member of the German big three and an apex luxury manufacturer.
