Asked by Aug 23, 2014 at 07:45 PM about the Cadillac DeVille

Question type: General

1 Answer

Follow the top radiator hose to a 'housing, looks like a pipe on an angle sticking out of a flange. Usually two bolts. Remove housing, you don't even have to take hose off. rteplace thermostat the SAME WAY the old one is in. There are marking on the thermostat "Block side "radiator side" Use a little high=temp silicone on both sids of gasket, do NOT over-torque. You will not lose much coolant. and do this on COLD engine
