Question about Cadillac DeVille

1 Answer

Vehicle is losing coolant but doesn't seem to be leaking when parked or steaming out when running. After driving for an hour it's 2 or 3 quarts low on fluid. When the fluid level is full the car is making a sound about 18 inches in from the back of the glove compartment that sounds similiar to the squeek that a leather car seat makes as it shifts foreward past the seat next to it.

I am experiencing unexplained coolant loss, no leaks but loses about a quart between oil changes

The most common cause is a leaking head gasket.
You can burn a gallon or more per month without any noticeable signs.

Vehicle overheating tips

If your vehicle engine coolant temperature gauge indicates overheating, if you experience a loss of power,or if you hear a loud knocking or pinging noise, the engine has probably overheated. You should follow this procedure............

Pull safe off the road, stop the vehicle and turn on our emergency flasher. Put the transmission in "P" (automatic) or neutral (manual) and apply the parking brake. Turn off the air conditioning if it is being used.

If coolant or steam is boiling out of the radiator or reservoir, stop the engine. Wait until the steam subsides before opening the hood. If there is no coolant boiling over the steam, leave the engine running. CAUTION: To avoid personal injury, keep the hood closed until there is not steam. Escaping steam or coolant is a sign of very hing pressure.

Visually check to see if the engine drive belt (fan belt) is broken or loose. Lock for obvious coolant leaks from the radiator, hoses, and under the vehicle. However, note that water draining from the air conditioning is normal if it has been used. CAUTION: When the engine is running, keep hands and clothing away from the moving fan engine drive belt.

If the engine drive belt is broken or the coolant is leaking, stop the engine immediately and call your mechanic of assistance.

If the engine drive belt is okay and there are no obvious leaks, you may help the engine cool down more quickly by running it at about 1500 rpm for a few minutes with the accelerator pedal lightly depressed.

Check the coolant reservoir. If it is dry, add coolant to the reservoir while the engine is running. Fill it about half full. CAUTION:Do not attempt to remove the radiator cap when the radiator are hot. Serious injury could result from scalding hot fluid and steam blown out under pressure.

After the engine coolant temperature has cooled to normal, again check the coolant level in the reservoir. If necessary, bring it up to half full again. Serious coolant loos indicates a leak in the system. You should have it checked as soon as possible at your mechanic's workshop.

Good luck.

Steam leaking from the under carriage

It could be due to the coolant pipe and hoses that go to the back if you have rear heat. If steaming, leaking and running hot I recommend that you don't drive the vehicle until the problem can be repaired or damage to the engine could occur.

I am losing transmission fluid but can't find a leak????? where can it be going

I take it that it is an automatic transmission, if it is draining that much fluid a month and you can't find any outside leaks it could mean there is an internal leak somewhere. If you see a pink milkshake color in your coolant then it could be the radiator transmission cooler which I believe wont cause an outside leak so you can start from there. It is located and is part of the radiator. Just follow the transmission cooler line and it will lead you the possible problem.

I have unseen coolant loss with no overheating unless coolant gets to low. Can the coolant loss be through the intake manifold gaskets? My vehicle is a 2002 Chrysler 3.8 in a Town and County van (No rear...

it is unlikely that it would be leaking through the intake manifold gasket as such, but loss of water is usually caused by leakage, but they are not always easy to find, depending how much water you are losing as to where it is leaking,sometimes if it is a leaking water hose at the clamp it will only leak when you first start the engine & stop when the engine warms up ( very hard to detect) it could be the head gasket is starting to blow check the exhaust pipe when the engine gets up to normal running temperature to see if there is any steam coming out if so that may well be the problem......hope this helps......cheers.

check your compression on combustion chambers, sounds like you have a blown head gasket losing that much coolant, steam and smell in the exhaust? you can probably tell easily by looking at the spark plugs

most likely a blown head gasket between a coolant passage and an oil passage not a cylinder . when coolant gets into a cylinder is when you will see the white smoke and the smell.

Coolant problem

Overheat could be a pulged up rad , but low on coolant ? it has to go somewhere. If you don't see any leaks , I am afraid that your head gasket might be leaking it into a combustion chamber.
Do you seem to have steam / vapour coming out of exhaust pipe more than usual ?
Hope that's not the problem , good luck
