Question about 2000 Cadillac DeVille
Where is the themostat on 2000 cadillac deville
On a 4.9L follow the upper radiator back to the engine. This should be the thermostat housing. The thermostat should be inside.
On a 4.6L the thermostate is in the housing which is near the water pump drivebelts "on the coolant crossover housing". If this is not clean I recommend you buy the Haynes for your DeVille. See page 3-4, illustration 3.14.
