Three problems related to radiator have been reported for the 1999 Chevrolet Malibu. The most recently reported issues are listed below.
Water light coming on intermittently - taken to dealership 3 times for repair. After warrenty,car regularly overheats and the light came on and book said 'coolant' problem. I had radiator flushed and filled with antifreeze. Car now continues to overheat. Mechanics (3 so far) said this is a common problem with Chevrolets. Cost would be $800 - $1,000 to repair leakage around lower intake gasket. I believe if this is a common problem with Chevrolets and it will continue to happen yearly, Chevrolet should be responsible for repairs.
Consumer stated that anti-freeze was leaking in vehicle for about 3-4 months. Consumer was told that there was a recall for the same problem. Consumer has not yet taken vehicle to a mechanic, but will do so soon.
Air conditioning - electrical failure, would flicker on and off. Engine - head gasket, faulty. Was replaced. Power window - regulator and motor faulty, the window just stop rolling up and down, did not show signs of faiure till it happened. In shop right now, not covered under manufacturer warranty. Other - cooling system, uses the infamous dex-cool coolant. The engine gets hot every time I drive it. Hot meaning two bars above middle. It usually resides in the middle. The radiator cap has been replaced twice and the head gasket was also suspected of being a problem related to this. The problem still exists and is going to the dealer tomorrow for another inspection. The worst time it occurred was after the head gasket had been replaced. The vehicle ran fine for two months. We took it on vacation to lake powell when the problems occurred again. The engine started to get hot. I turned off the a/c and turned on the heat. This was able to get the engine driveable without causing damage to it. My worry is that this will happen to my wife on the freeway or driving home to see her parents. Had this occurred the first time with just her in the car she would not have known what to do and would have been stranded.
