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.

NOTE: This thermostat fits late model 2009 ½ Pontiac G8’s with the water pump housing on the driver side (when looking at the front of the engine).
