Two problems related to radiator have been reported for the 1999 Oldsmobile Bravada. The most recently reported issues are listed below.
The veichle wants to flip over by itself when driving down the road the seat belts are twisted the radiator leaks here and there along with the transmission fluid and sometimes the oil leaks.
The heater has failed to work this year at all. The system was flushed and radiator fluid changed with Oldsmobile rated fluids. This vehicle has had no major problems and has been good other than seatbelts not locking and dome lights are inoperable. I am going to assume it could be the heater valve and get that replaced so hopefully that does the trick.
