Question about 1999 Cadillac DeVille
Posted by Anonymous on
Unfortunately, with all you have done, it appears you may have a blown head gasket or cracked head if you cannot locate any other place that the water is leaking from. First of all I would check the car for leaks after you have been driving it and turned it off. The pressure builds up in the system right after the car is turned off and you may see leaks then that you never see. If you still dont see where the water is leaking from by doing this, then pull the oil dipstick up out of the tube and check your oil. If there is a white milky substance on the oil then there is water getting into you oil which indicates a bad head gasket or cracked head. If you still dont find water in your oil by doing that then your water/coolant is probably escaping through your exhaust by water vapor. Check your exhaust while the car is running (after it has warmed up) and see if there is any water vapor coming out. Put your hand in front of the exhaust and you should feel the moistness if there is water vapor, but you should see it as well. If so, again, it is a head gasket or a cracked head. Make sure you look for all leaks in hoses, etc, (including inside passenger floorboard from heater core leaking) before you totally conclude that this is the head gasket or a cracked head. If you cannot locate any other source for the leaks then the only thing left is the head gasket or head.
