My car was overheating. I had the water pump replaced and the radiator and it continued to over heat. I took it to the dealership where they told me that I my cross over pipes were leaking and I would need a new engine. I found this very hard to believe when I have taken such good care of the my care with scheduled oil changes and the works. I love my car and I don't want to get rid of it, please help me.

Tl*the contact owns a 1999 cadillac deville. While driving at an unknown speed the vehicle stalled. The dealer performed a diagnostic evaluation of the vehicle and located a coolant and water pump leak, as well as engine failure. There was pressure build-up and head gasket failure, which contributed to the failure. The dealer estimated that the repairs would cost over $3,000. Although there was a customer safety improvement campaign, the manufacturer denied the contact's claim due to the current mileage on the vehicle and because she was not the original owner. The current and failure mileages were less than 86,629. Updated 04/29/30.

First time engine failed while driving on interstate at approx 75 MPH. Engine completely shut down while passing semi. All lights on dash came on and total loss of power steering. After serious scrambling to get car off road and bring to safe stop attempt to restart was successful and trip of 600 miles continued w/o incident. Five days later same thing occurred on suburban street in heavy traffic at approx 45 MPH causing a lot of consternation by drivers behind me that did not understand why I came to sudden deceleration. Took car to cadillac dealer and they found no problem. They charged me $112.50 for engine driveability and performance diagnosis and did replace a defective egr valve which I feel had absolutely no assoc w/ stalling problem. I think after looking at all the other filings of this problem in the federal safety agency records, that cadillac has a real problem and had better get on it before someone gets killed. Dt

Engine overheated-loose head bolts (the federal safety agency item # sb6089931). Antifreeze vapors came in passenger compartment through A/C vents for over 20 minutes and then a large steam explosion inside car when engine overheated. A fine mist of vapors entered the car without our knowledge as we thought something was wrong with the air conditioner as the inside air temperature kept slowing rising until steam explosion occured. ( hot antifreeze vapors were forced through the air conditioner vents by the deforming of the rear hood gasket by incoming 65mph air flow and a defective front hood gasket). If this car had a full time coolant temperature gauge this incident and injuries might not have happened. Cadillac does not provide an active temperature gauge on this car as other manufacturers do. Only way to determine coolant temperatures is to push the information button on dash which separately informs you of engine functions. No warnings in operation manual, no warning labels in engine compartment as to potential dangers of dex-cool exposure nor information on the day of engine failure from cadillac road assistance personnel at their 800 number). Only warnings of engine overheating are emitted -after the car has overheated! Injuries to myself were: severe, very painful eye inflamation in both eyes( eye doctor examination in october 1999) instant cataracts with large black spots in both eyes 30 days after accident. Right and left sides of face presently have chemical burns on cheeks and throat. In april, 2000 I had very difficult breathing problems. I went to the hospital emergency on 2 different days with breathing problems. Breathing problems were diagnosed as chemical induced asthma from dex-cool antifreeze with 2-ethylhexanoic acid inhalation. At present I live in hell each day with asthma from this cadillac vehicle. Engine was rebuilt in september, 99 and a new engine installed on jan. 28, 2000. Front brake rotors rusted up in february, 2000 after 16 days of sitting idle.*
