Thermostats, Housings & Fillers

Water Neck, Thermostat Housing, Coolant Housing…basically they’re all names for the same thing. This is where the upper radiator hose is installed, and also contains your thermostat. Pit Stop USA offers stock replacement to replace a leaky or cracked one, or you can dress up your engine with a anodized or chrome finish. We also offer 360° swiveling models for your custom cooling system applications. To complete your high performance coolant system, Pit Stop USA recommends the use of a low-temp thermostat. Low-temp thermostats improve performance in two ways: first by inducing less heat into the intake air and second by reducing the engines tendency to detonate.
