Thermostats & Components

Car engines are designed to operate within a relatively narrow temperature range. It goes without saying that serious damage can occur if that temperature is exceeded and an engine overheats. You might be surprised, but there is also the other side of the coin. An engine can be damaged and performance and mileage can suffer if the engine runs too cool as well. To keep the optimal temperature range every vehicle has a thermostat, a special device that regulates engine operating temperature to prevent its damage and ensure good performance, fuel economy and minimal emissions.

    In just about any vehicle the thermostat mounts in the water outlet where the upper radiator hose is attached. The thermostat contains a heat sensing element exposed to coolant. It restricts coolant flow through the radiator to allow the engine to warm up as fast as possible. As the engine warms and the coolant reaches the thermostat’s rated temperature, it opens and allows coolant to circulate. If coolant temperature drops, the thermostat closes, decreasing coolant flow, thereby regulating engine temperature and maintaining optimum engine performance and horsepower.

    A thermostat can fail and stick in the open or closed position. If it fails in the closed position, coolant flow will be restricted and the engine will overheat, possibly causing extensive damage like a blown head gasket, cylinder head warpage, and excessive stress to other engine components like pistons, rings, and cylinder walls. If the thermostat fails open, the engine will be slow to warm up, and may never reach the proper operating temperature. This can result in poor output from the heater in cold weather, and also cause performance, fuel economy and emissions problems.

    Engine coolant temperature is an important input to the powertrain control module (PCM) that controls engine function. Low coolant temperature may prevent the engine from going into closed loop where it operates most efficiently, and the air/fuel mixture may stay rich resulting in poor fuel mileage and excessive emissions. Exhaust gas recirculation (EGR), evaporative emissions, and transmission torque converter lockup functions are also dependent on coolant temperature. An engine that runs cold may never evaporate the moisture that is a byproduct of combustion, which can contaminate the oil and cause sludge to form.

    Regardless of your thermostat’s mode of failure, we have the replacement thermostat that will restore proper cooling system performance and engine operating efficiency. When choosing a replacement, always select a thermostat with the vehicle manufacturer’s recommended temperature rating. In addition to thermostats, we also have the necessary gaskets and seals required for installation. And if you should find that your water outlet or thermostat housing is cracked, corroded or otherwise damaged and unusable, we have OE spec replacements so you can complete the repair.

    Direct Fit
    Perfectly seals thermostat into housing. Don’t confuse with O-ring that seals housing to water pump (which is only in some models). But you won’t need it if you bought a housing with thermostat already installed. Fits great, identical to factory.
