FAQ:

Q: What is the thermostat location on a Buick 3800 engine?

A: The Buick 3800 engine, used in several Buick models over the years including the Le Sabre, sported a V6 engine configuration. The thermostat on the General Motors-designed engine is located on the intake manifold.

Q: How do you remove the radiator hose from a thermostat cover?

A: Remove the radiator hose from the thermostat cover. If the clamp is original, use pliers to squeeze the compression tabs together then pull the hose off the cover. If the clamp is an aftermarket band clamp, loosen the clamp using a socket and ratchet. With the clamp loosened, pull the hose off the thermostat cover.

Q: Where is the thermostat on a GMC Sierra 1500?

A: The thermostat on the General Motors-designed engine is located on the intake manifold. This is the easiest thermostat location for a do-it-yourself repair since you do not have to drain the radiator and work from under the car as you would with a vehicle with an engine block-mounted thermostat.

Q: How do you replace a thermostat on a Chevy Silverado?

A: Pull the thermostat out of the intake manifold and place a new one into the manifold. The thermostat sits on a lip inside of the hole. The end of the thermostat with the large spring on it sits inside the hole. Place a new thermostat gasket onto the intake manifold and secure the thermostat cover on top of it.
