Mr. Gasket high-performance thermostats are designed to resist large variations in coolant pressures that can occur at high rpms. Under these conditions, coolant temperature and pressure fight for control of the thermostat, keeping it from opening at its designed temperature. These balanced high-performance thermostats have brass-and-copper construction, and open at the right temperature regardless of engine rpm.

Water necks help to hold the vehicle's thermostat in place as it opens and closes—to regulate the flow of coolant through your engine. The opening in the water neck created by the thermostat allows coolant to flow from the radiator back to the engine. Order the model recommended for your vehicle.
