Thermostats can become stuck in the closed position and cause an engine to overheat. In this event, the coolant temperature will likely rise quickly to the boiling point determined by the system pressure cap and exhaust to the ground. This condition is very rare and in most cases the thermostat is not the cause of an overheating engine.
These low-temp thermostats dramatically reduce operating temperatures, while increasing thermal efficiency and your engine's performance in the process. Racers know that a cooler running engine is a better performing engine. This new thermostat replaces the factory unit, allowing coolant to circulate at lower engine temperatures, keeping the engine cooler. Not legal for use on pollution controlled vehicles.
