email@example.com Posted June 13, 2008 Report Share Posted June 13, 2008 I bought a 1999 Cadillac seville november of 2006. About april of 2007 I was driving on the highway and the cars temp gauge mysteriously went up to the H and i had to pull over and shut off the engine for a few minutes. I turned it back on and it was fine. It then did this to me off and on for a while and evetually I quit driving it. We replaced the radiator and the thermostat in the car. Now I just resumed driving the vehicle about a month ago. It still over heated on me when driving for a while or on the highway. I bought a combustion leak kit from NAPA and tested it. The fluid turned yellow which means a combustion leak is present. I then took it to my local Cadillac dealer they looked at it, and they told me I do have head gaskets leaking and here is the Engine diagnostic report they gave me: ENGINE DIAGNOSTIC: The vehicle is overheating on the highway. Client says he has done test for exhaust gases in the cooling system and it failed test. Please advise. When started the car ruan a little rough for a while. Test cooling system for exhaust gases and tested positive. Engine has oil leaks-- Lower crankcase seals and oil manifold and rear valve cover gasket. Also noticed traction control light on checked for codes had brake lamp switch code. They then gave me an estimate to repair all of ths and the estiamte was $5,550. I declined to get the car repaired right now because that repair is about as much as the car is worth! Does any1 have any suggestions on what you would do? Im stuc, Think maybe trading it in as is to a dealer and not saying anything about it. Link to comment Share on other sites More sharing options...
