Question about 2002 Cadillac Deville

1 Answer

ANTIFREEZE LEAK I'm losing about 1/2 pint of antifreeze over a two or three week period. After I fill reservoir I loses it sporadically and after it gets down about one inch it stops losing fluid. The leak seems to be toward the front of the engine and a bit to the right. It never seems to get low enough to cause overheating although the low antifreeze light does come on.

Car overheats, losing antifreeze...the overflow coolant reservoir leaks out onto the ground when I try to put antifreeze in there - so could this cause my car to overheat? I have had the antifreeze drained...

Hello, if your car has a blown head gasket and exhaust is entering the coolant system, it will continue to run hot until it is repaired. Using pure antifreeze will make it worse. It should be at least 1/2 water. If the coolant reservoir didn't leak you could probably drive a few more miles, but not many, before it overheats again. All that is doing is giving you a little more capacity. If you continue to run the engine hot you are going to do more serious damage to it.
I suggest you have the head gasket replaced. That stuff you put in there seldom works, and if it does work, it's only temporary.

I hope this helps.

Engine is losing antifreeze. New radiator, thermostat and head gasket. No water/antifreeze in the base pan. Pressure tested and ok.

If it is not leaking try taking the top off the reservoir, crank it and let it warm up, if no coolent rises into the reservoir when it is warm, add some coolant until it just starts to fill the might go down some then and more till it rises. if it does not rise or fall. Turn it off, let it cool the fill to the mark. If this aint it then it might be leaking....check the heater hoses and inside the care for coolant. might be the heater.

New water pump, thermostat. Heater blowing tepid to cool air since replaced.

sounds to be a faulty thermostat did your car over heat my vehicle does the same thing its the thermostat when its cold out your vehicle loses all its engine temperature and blows cold air make sure you use 50/50 antifreeze

I am not sure if it the water pump, but we are losing water and there does not seem to be any leak in the coolant reservoir.

A water pump would not likely cause loss of water,mainly overheating problems.First fill the radiator full and the overflow full,you can use water to do this,it is not necessary to waste antifreeze.You do not need a 100% mix of antifreeze.During winter where it gets below freezing,you really only need about 70% antifreeze to prevent freeze.Maybe a little more if you are 1 or 2 states from Canada.If you open the hood and let the car run,watch the tubes and the radiator and the hoses,follow anything hooked up to the radiator.If you end up getting a big leak or puddle,dilute it down with tons of water.Birds for some reason like the taste of antifreeze however it kills them.Good luck!

Tube disconnected fron antifreeze holding tank to wherever it is supposed to go keeps losing antifreeze

there is two small hose come out from reservoir. on of them(rear one) goes to coolant bypass line it is a small metal pipe goes all the way to thermostat housing other hose(front) connected to radiator.
if you lose coolant from the bottom breathing hose on reservoir you may have air in coolant system you should bleed the system.

1998 cadillac catera anti-freeze leak

First things first don't use Dexcool.

It would happen only once in a while likely because the overflow bottle doesn't always fill to the point of where the leak is located. It would be very easy to unbolt the bottle and fill it with water to find the leak and patch it up.

Antifreeze leak only when car cools down

There should be no anti-freeze under the valve covers, just valves, rockers, springs, and oil. If you are getting any antifreeze leaks at the valve cover then you have a cracked head. Since the engine has been pressure tested and has passed, my guess would be that the coolant reservoir is overfilled. Drain it down to the correct level and see if it does it again. If you are getting a strong sweet antifreeze odor when the car is running, you may be in need of a heat core. My PT Cruiser would leak sporadically, and after running a pressure test, it turned out that the 16 pound radiator cap I had on the car was losing pressure at around 8 pounds. so it would only lose antifreeze when it was really hot and/or I was running the AC.
