Engine Coolant Thermostat Housing Gasket - Pontiac Bonneville 77-84, Firebird 77-81

Engine Coolant Thermostat Housing Gasket - 25148 / 33631

Stant's STAT LOK adhesive-backed thermostat gaskets cut installation time by as much as 50%. The adhesive backing holds the thermostat securely centered in the counterbore, leaving both hands free to align and bolt down the outlet casting. No sticky, toxic gasket cement is required. With a knuckle-saving Stant Stat Lok gasket holding the thermostat in place, the thermostat won't drop out or become misaligned and cause the mounting flange of the outlet casting to crack

• Gaskets are cut to specific application requirements.
