unfortunatly there is only one answer to this question and that is to take it to a dealership or some reliable mechanic. The car has to be on a hoist, and the complete motor and transaxle has to be removed. There is really no oil pan on the northstar. It is the upper and lower engine components that house the crank etc. Sorry about this one. I own a 94 and a 97 and the problem is the same for both of them . The 94 has cost me 3400.00 to complete, and it is going to be the same for the 97. The gasdket by the way costs 35.00. Go figure. The engineers at GM have this one worked out so their dealerships can count on one of these major repairs starting around 160,000 Kms.

A thermostat gasket is a gasket for a thermostat, a head gasket is a head gasket. The top part of the engine needs to be disassembled to repair the head gasket.

The dealership said the book lists it as a 5 hour labor job. Apparently they have to remove motor mount bolts and transmission bolts, literally lift the engine away from the framing in order to replace the oil pan and gasket. What a freakin nightmare! They estimated $2,000 at the dealership to do this repair. Luxury costs - a lot...

The first step in how one can replace a thermostat in a 2001 Cadillac DeVille is to remove the housing which surrounds the old thermostat. The radiator hose will need to be removed and drained and then the thermostat can be removed. Remove the old thermostat gasket and then insert the new thermostat as well as the new gasket. Attach the radiator hose and place the drained fluid back into the radiator filler cap.

Assuming you have not noticed and leaks or puddles near the car the next thing would be to watch for steam coming out of your tailpipe. If there is you probly have a bad head gasket.

Just remove the 2 bolts that hold it on and clean where it mounts and put the new on with a new gasket.

If that has the Northstar engine, there is many hours involved. The engine and trans must be dropped out from under the car along with the subframe.

If it's the base Sedan Deville with the 4.9 liter engine, not the Northstar, it is located on top of the driver side of the intake manifold. There are two small bolts that hold it in. Remove those, pull the housing off. The thermostat is directly underneath. You can then pull it up and off, you might need to use some force to pop it loose. After that, it's just reverse of the above to install the new one. Just make sure to use a new gasket and make sure that all of the old gasket is off of the thermostat housing and the intake manifold.

You can change the head gasket by removing the valve cover. Remove the gasket and clean the gasket surface. Put the new head gasket on the cleaned surface.

About $40 for the gasket... And about book value of your car to replace them.

NO NO NO you can i guess but it will ruin your engine. You either have a cracked block or blown head gasket i would guess. Moisture in the engine will destroy it. In addition to a headgasket or cracked block (unlikely), would be cracked cylinder head, intake manifold gasket or manifold. What kind of car, what size engine? 1999 CADILLAC DEVILLE

yes you have to change the pan gasket when doing the timing chain
