Looked it up online and looks like it's on the front of the water pump in a thing called the coolant inlet housing. one end of it looks something like the letter y and the other end, where the thermostat is round. hope that helps

I think you are having a 4.9L Cadillac. If so please follow the upper radiator to the engine. This would lead to the thermostat housing which holds the thermostat.

I am trying to replace the thermostat on my 1999 Cadillac DeVille but cannot locate the housing.


Hello: Follow the bottom radiator hose on the drivers side to where it connects to the engine. Remove two bolts (10mm head) that will allow the hose to engine adapter to come off, the thermostat is under there. Note how the old thermostat comes out and be sure to install the new on the same way.

Where do i find the thermostat and how do i replace it on a 2001 cadillac deville


The thermostat in the northstar engine is located at the bottom radiator hose (unlike most conventional cooling systems), the hose connects into the housing where you will also find the water pump.
Remove the hose from the housing,then remove the two bolts on the flange,the thermostat can then be pulled out.
Take note of the orientation of the thermostat as you remove it.
Don't forget the new gasket, you may have to order this separately.
