Thermostat

Efficiency of the engine cooling system is dependent on the accuracy of the thermostat. The thermostat controls the flow of coolant within the engine. It opens when the proper operating temperature of the engine has been achieved to allow the coolant to enter the engine. The thermostat is located between the engine and the radiator. Engine overheating, erratic temperature changes, low temperature readings and coolant leakages indicate a failing thermostat. Always replace your thermostat regularly for efficient cooling of the engine. If you begin to experience any of these issues within your vehicle, purchase your brand-new, high-quality thermostat through German OEM Car Parts.
