Shop Mercedes ML350 Replacement Thermostat

Liquid cooled cars like the Mercedes ML350 use a thermostat to regulate engine temperature. The thermostat plays a vital role in engine cooling, warming, and helps prevent wear. Engines operate most efficiently when they are warmed up and it is the job of the thermostat to regulate that process. This piece does not let coolant flow out of the radiator until the engine is at a designated temperature. A common engine temperature is about 180 degrees Fahrenheit. Letting the car warm up quickly by holding back coolant reduces wear and emissions from the vehicle. The thermostat for the Mercedes ML350 operates by melting wax as the temperature nears the designated level. When the wax begins to melt it expands and opens a valve that allows coolant to pass by into the engine cooling system. Parts Geek provides replacement thermostats for the Mercedes ML350 online for convenience of shoppers and mechanics.
