    Average rating:  4.5  4.5 - 1 review

    Direct Fit
    Perfectly seals thermostat into housing. Don’t confuse with O-ring that seals housing to water pump (which is only in some models). But you won’t need it if you bought a housing with thermostat already installed. Fits great, identical to factory.
