Locating thermostate - 2000 Oldsmobile Silhouette

The thermostat housing is where the top radiator hose connects to the engine. It may have a coolant temp sensor in it as well, it has a wire plugged into it. Replace them both.

The water pump is located on the passanger side of the engine. Look right below the timing chain cover and there is a pully and belt on the water pump. You will have to remove the water pump and thermostate together then seperate them after you get them off the car. I would recommend replacing the thermostate also (cheap fix). You will have to remove the belt and pully before you can remove the water pump. Hope this helps....

follow the top rad. hose to the motor, it should b there

The T-Stat is located under the car up front just in front of the oil pan. Watch the video at this link, the owner in the video is replacing the thermostat housing gasket which contains the thermostat. Please be safe and support the car on a safety jack stand, never raise and work under an unsupported car unless you are prone to a death wish.

follow the top radiator hose to the engine....your thermostate is located at the end of hose...take that end of hose off and thermostate is screwed into engine unscrew and take out .

Go to any autozone parts store as they offer a free service where, in this case, they will show you where the thermostat is, and show you [usually actually help you] do the repair.

The drivers side of the engine block behind the alternator. It is not necessary to remove the alternator to replace the thermostat. You will have to remove the ecm.

on the drivers side of engine below the water pump drive belt the upper rad hose is attached to the housing that it is in

If it's not up top it's behind the lower hose. I know it's behind the lower on the 2.7 litre motors.
