Question about Cadillac DeVille

1 Answer

1999 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.

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

Tip

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.

My 99 Jeep grand cherokee coolant boiling/steam.


This could be a lot of things. If you dont use the right mix of coolant and water it can overheat. The raidiator cap might be bad, the fans might not be working, the thermostat might be stuck, the raidiator might be gummed up with deposits. The big worry now is whether or not you have a blown head gasket or warped the head.

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.

This is for a 1999 automatic jeep cherokee...my engine oil dipstick was at the add level, so i added a quart. turned engine on put it in drive , checked the transmission fluid. left it running and went to...


Yes it is a problem, you can have a waterpump that leaks as the engine runs, when the vehicle warms up coolant expands and goes to the resovoir,as you turn the engine off and the engine cools off the fluid in the resovoir reutns to the engine but here the problem the radiator cap cant do its job when the water pump leaks

Could you tell me how to get the correct oil level hieght in my auto transmission on my 2005 4.7ltr


After warming the trans up by driving the vehicle, park on level ground and with the car in park with the engine running pull the transmission dipstick out and wipe with a rag. Put the stick all the way back in and check the level by reading the amount of fluid on the stick and comparing the position of the fluid to the markings on the stick. If you need to add fluid use a funnel to add fluid through the dipstick tube. Add a quarter quart at a time allowing time for the fluid to drain all the way down the tube before checking the fluid level again and adding another quarter quart (it sometimes takes five minutes or so for the fluid to drain completely down the tube). If you are losing fluid on a regular basis you have a leak and need to have the trans checked. It should not normally use fluid.
