How to Change the Thermostat in a 2002 Oldsmobile Silhouette Mini Van

by Zyon Silket

The thermostat is pretty easy to access in the engine of a 2002 Oldsmobile Silhouette Mini Van. The thermostat's housing rests beside the engine head. The easiest way to locate it is to follow the upper radiator hose from the radiator to the point where the hose connects to the engine. The hose connects to the thermostat housing.

Remove the tension band clamp from the radiator hose by squeezing the tension tabs together with a pair of pliers. With the tension released, pull the hose off the housing. A small amount of fluid could drain from the hose. To minimize this, hold the hose vertical to drain the fluid back into the Radiator.

Remove the three bolts that secure the housing to the engine with a socket and a ratchet. Pull upward on the housing to remove it from the engine.

Pull the old thermostat O-ring gasket out of the mating surface of the thermostat housing and replace it with a new one.

Pull the old thermostat out of the engine. Take note of the its orientation. The end with the spring rests inside the engine. Place the new thermostat into the engine in the same manner.

Place the thermostat housing over the thermostat and secure it by tightening the three bolts.

Push the radiator hose back onto the thermostat housing and secure it with the tension clamp.

Warning

  • Do not remove the thermostat while the engine is hot. Radiator fluid is very hot and could cause serious burns. Allow adequate time for the Oldsmobile to cool down before completing this job.
