Mercedes 240D Replacement Thermostat Information


The thermostat on your Mercedes 240D is a small, inexpensive part, but one that's vital to the proper operation of the vehicle's engine cooling system and the passenger cabin heater. If the thermostat malfunctions it should be replaced immediately, and PartsGeek.com carries a full line of replacements designed to fit Mercedes 240D sedans, covering model years 1974-1983. This includes thermostat units from original equipment parts providers Behr and Calorstat.

The thermostat is a valve made to open at a pre-designated temperature setting once the engine coolant has reached operating temperature. A broken thermostat that cannot open will prevent the engine coolant from traveling to the radiator where it may be cooled. This is a dangerous situation, posing the threat of engine damage through overheating. A thermostat stuck in the open position won't allow the engine to reach proper operating temperature, which will reduce engine and cabin heater performance.
