Cadillac DeVille

Could be from a variety of things. Commonly overheating occurs when the car is low on coolant, broke thermostat or the radiator needs repairs.

The compressor is located under the car in the rear over the axel passenger side. Remove the bolts fittings and electrical connector and replace in opposite of removal instructions You can override the system for about $900.00, it is too expensive to replace through the dealer.

Sounds like a blown head gasket

U find the cracked or disconnected Vaccume hose - probably near the carb or fuel injection on the intake manifold,but sometimes the vac modulator under the dash goes bad.OR a bad connection @ the Firewall.

Trouble code P0440 means:Evaporative emission control system malfunction

Coolant temp is about 196F. Mine runs cool on a highway, 2 notches below the red line on hot days in traffic.

I have told that reason my 94 cadilac sedan deville when it rans for while it wont run smooth is the transmission pump and how hard is this problem to fixs.

On a 92 DeVille, the ECM (Engine Control Module) is behind the dashboard on the right side. Access is through the glove box opening by removing the 6 philips head screws (you will need a stubby #2 philips screwdriver) and wire connectors from the back. Once the glove box is out the ECM is the silver box 10 X 7 X 1-1/2" with a red white and blue wire connectors. It appears to be one piece, but it is actually two, inside (under a 1 X 2" door is a PROM (looks like a computer chip). If you are changing the ECM, transfer the PROM to the new ECM (engine will not run without one).

My 99 made a loud howling noise that seemed to come from the air cleaner. It was actually the Idle Air Control Valve(IAC)motor mounted on the right side of the throttle body. It is a silver cylinder mounted by two bolts and has an electrical connector on the end of the cylinder. It get gunked up with soot it is about $80 new. You can clean it with solvent, but it is only a temporary fix. Best replace it before it goes south. I would suspect the power steering pump. Check the P/S pump fluid level. If it is full, then listen carefully to the pump. If it is whining, it is bad.

Look towards the car in the front. The plug is located bottom left front of the radiator. You will need square drive to loosen the plug.

Bad shocks

Yes...It is possible. depending on your tire size. I have 22's on my 97 deville and have 24's on dodge charger with no modifications... the tires are rubber bands though, very bumpy ride, 20's look good and have a smoother ride, but bigger is better, ha Most online sites will not allow you to choose a wheel larger than 20 inches for this type of car, because they r not sure on every car dimension. but if you call a local shop they should tell u.

Drain the radiator by removing the lower hose. Then remove the fan shroud then the oil cooler lines and upper hose/ Then the bolts that hold it in and pull it out. Dispose of the used coolant properly.

under the lower intake manifold

Don't know where you are located ,,but,, most of the auto parts supply houses have the codes and readers for free or can be borrowed. Some will even do it for you .AUTO ZONE OR O'RILEYS for example

if its a 4.9L motor its up top right underneath the air intake assembly, if its the 4.6 northstar its underneath towards the front of the vehicle.

No power, shhhh sound from ehaust pipe when engine is revved up

I had a 78 eldo eldeora and i sold it to a msn in utah

The 1996 Deville drain plug is in the bottom of the radiator close to the bottom hose. It is in a very hard place to reach.

i believe its 5x4 3/4

its 5-115
