Mercedes R350 Replacement Thermostat Information


The R350 Mercedes thermostat is an important part in a trendsetting luxury crossover wagon. Operated by 12-volt electricity, the R350 Mercedes thermostat opens and closes the coolant circuit. A sensor in the coolant line reads the temperature. Based on this reading, the on-board computer determines when the thermostat valve opens and closes. A separate radiator fan keeps coolant at a stable temperature.

Vital to the operation of the radiator and engine, the R350 Mercedes thermostat allows the engine to cool properly for peak operation. If the thermostat doesn't work, the engine could run too cool causing fuel mileage to suffer due to a poor fuel to air ratio. If the engine runs too hot, it will be damaged severely. The Mercedes R350 is a luxury concept crossover with the highest quality parts. However, thermostats can break or fail and must be replaced with quality parts fitting the platform.
