Thermostat Gaskets
A thermostat gasket seals the joint where the thermostat housing meets the engine. That seal keeps coolant in the system and air out, so the thermostat can control engine temperature. Most people replace the gasket any time the housing comes off, such as during a thermostat swap or a cooling system refresh. A seep or leak at the housing is another common reason to fit a new one.
We currently have 2 thermostat gaskets in stock, one from Cometic Gasket and one from Gates. The Cometic 2003+ Dodge 5.7/6.1L Hemi Thermostat Housing Gasket is listed for Dodge Hemi engines. The Gates 82-88 Camaro / 69-71 Mustang / 90-05 Mazda MX-5 Miata Thermostat Gasket is named for those applications.
When choosing a gasket, keep a few points in mind:
Match the gasket to your engine, not just the model name, since housings can differ.
Compare the shape and bolt holes to your old gasket or housing.
Clean both mating surfaces fully before fitting a new gasket.
Plan to replace the gasket whenever you replace the thermostat.
To narrow it down, pick your vehicle to see what fits.
