    Q:
    How to replace the Thermostat in V6 and V8 engines on Pontiac Firebird? Posted by Niles W.
    A:
    Disconnect the negative battery terminal and remove the air cleaner on V6 and V8 engines, labeling all detached hoses. Drain the cooling system below the thermostat level and disconnect the upper radiator hose. Remove the thermostat housing bolts and separate the housing from the engine, possibly removing the alternator bracket first. If a TVS switch is present, disconnect vacuum hoses and unscrew the switch. Remove the thermostat, noting its orientation. Clean old gasket residue from the thermostat housing and engine sealing surface. Apply a 1/8-inch bead of RTV sealant to the engine's sealing surface, place the thermostat, and position the housing with sealant and a new gasket. Tighten the bolts to the specified torque. Reinstall any removed parts, reconnect the upper radiator hose, and reinstall the air cleaner.
