Predator Hummer H1 Duramax Low Temperature Thermostat (Pair)
Duramax-178Product Details
Predator takes the performance to the next level with the Mishimoto Thermostats. These thermostats are built with high-quality wax and are shipped with new rubber gaskets (where applicable) for a good, leak-free seal. They are then digitally calibrated for precise operation.
Mishimoto Thermostats open up at a slightly lower temperature than OEM or standard thermostats once your engine is fully warmed up. This allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Mishimoto thermostats will maintain optimal temperatures to efficiently cool your application.
