Detailed Product Description

This engine coolant thermostat features a bottom by-pass design that allows coolant to circulate through the engine block before the thermostat opens, promoting efficient warm-up and preventing overheating. The jiggle pin weep hole helps release trapped air, reducing the risk of air pockets in the cooling system. With a start to open temperature of 180°F (82°C), the thermostat ensures the engine reaches optimal operating temperature quickly and maintains it effectively. The part’s sealing flange outside diameter measures 2.13 inches, and the flange thickness is 0.05 inches, providing a secure and leak-resistant installation. The thermostat does not include gaskets or installation tools, so these should be sourced separately if needed.
