1966-70 GTO Thermostat Housing, Aluminum

Fits GTO, Tempest and LeMans

These aluminum thermostat housings are an exact reproduction of what the factory-installed on all V8 engines equipped with either 2-barrel or 4-barrel carburetors. These cast aluminum housings have a machined mounting surface for a leak-free seal. Another great feature is the original GM number stamped directly into the housing. Reproduced using an original part, this housing also connects the upper radiator hose in the correct location.
