How to Change a Tahoe Thermostat

by Zyon Silket

The thermostat on the Chevy Tahoe regulates the coolant temperature as the coolant exits the motor and goes back into the radiator. For this reason, the thermostat is located under the water outlet housing on the engine's intake manifold. As the thermostat wears out, it cannot properly regulate coolant temperatures. The result is the engine overheating, and in some cases, engine underheating. Both situations could cause serious damage to your engine.

Trace the upper radiator hose to the water outlet housing. The hose connects to the housing.

Remove the two bolts that secure the outlet housing to the intake manifold of the engine, using a socket and ratchet. Lift the hose and the housing upward to drain any excess coolant back into the radiator. Wipe off the bottom of the housing with a clean towel and then push the hose and housing off to the side so you can access the thermostat.

Lift the old thermostat out of the intake manifold of the Tahoe and discard it.

Clean the old thermostat gasket off the intake manifold and clean the surface with a towel.

Place the new gasket onto the surface of the intake manifold.

Place the new thermostat into the intake manifold. The end of the thermostat with the spring submerges into the intake manifold.

Place the water outlet housing onto the thermostat gasket and secure both into place using the bolts, socket and ratchet.
