Product Details and Specifications

This engine coolant thermostat housing assembly is crafted from a combination of aluminum, stainless steel, and copper, providing a balance of lightweight durability and corrosion resistance. The silver finish complements the engine bay while resisting wear. The included paper gasket ensures a tight seal between the housing and engine block, preventing coolant leaks. The thermostat is calibrated to open at 170 degrees Fahrenheit, allowing coolant to flow through the dual outlet ports (1.38 inches and 0.51 inches in diameter) once the engine reaches operating temperature. The jiggle pin feature helps eliminate air pockets in the cooling system, promoting consistent coolant circulation.
