    Q:
    How to remove and install a Thermostat on Chevrolet Corvette? Posted by Vathana S.
    A:
    To remove the thermostat, disconnect the cable from the negative battery terminal and drain the cooling system. Then, disconnect the radiator hose clamp and remove the hose. Remove the bolts and lift off the thermostat housing cover, tapping it to break the gasket seal. For installation, mount a rubber seal and place it in the housing and install the thermostat housing cover and bolts and tighten them.
