SOURCE: changing the thermostat 2000 cadillac deville

The pressure they work within is usualy information on your radiator cap or owners hand book.Your thermostat should be a 180 degree but can vary The 180 is in reference to the heat required to open them so water can flow through and be kept at a more or less constant 180.There are other temp ranges for a wide variety of applications and 180 is the standard one for most vehiclesThe radiaor and water system is pressurised to lower the boiling point of the water The higher the pressure the lower the boiling point

This can be a major operation. Go to public library and see if they have a chilton repair book on this car. The pump has about twenty bolts af various sizes and torx head bolts.

If you like go ahead and let someone sell and replace your transmission but here is my suggestion! Check around and see if you can find a minor vacuum leak! This can simply be the big round hose that goes from the fuel injection to the power brake hub! This is normally a push in connector which has about a 1/2 inch hose clamped on it! If there is any kink or the connector is not in correctly a leak will occur and the transmission will shift rough as though you will be thrown out of the vehicle! Try unplugging this connector and plug it back in hard and straight and maybe you will be lucky and fix your problem. If the vacuum is correct your transmission will shift better than you have ever experienced!

Radiator lock


Do you mean trapped air in the system? Put on all the caps and run the motor up to operating temp, drive it around to circulate the water. The bubble will migrate to the expansion tank, all by itself. Allow the motor to completely cool off, and it will draw water from the expansion tank. If you notice the expansion tank has a lower coolant level, the bubble has escaped.
These systems are engineered to do this automatically. A system needing bleeding would be bad engineering.

COOLANT LEAKS ONLY WHEN CAR IS BEING DRIVEN. NO LEAKAGE ON GARAGE FLOOR. INTERMITTANT CONDITION. 2001 CADILLAC DEVILLE


From the way you describe it, It is likely the pressure cap on the surge tank (expansion/overflow coolant tank).
It is probably worn and no longer able to hold the pressure.
The cap is an inexpensive replacement so do this first.

Where is the themostat on 2000 cadillac deville


hi. 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.

There seems to be no recovery tank for my radiator is there supposed to be one


On the northstar engines, there is no "recovery tank".

You will have a Surge tank (or expansion tank).

It's there for two reasons.

1...to allow for expansion of the coolant.

2...To purge air out of the system (the cooling system is self purging on these engines).

In your car,I believe the tank is on the drivers side close to the strut tower.

Water coming from engine into overflow tank


Sounds like an overheating problem, best to get it checked, maybe thermostat stuck closed, pluged radiator, head gasget, cracked head.
