1991 Ford Thunderbird ProblemsCoolant Loss, Engine Overheating, White Smoke From Exhaust
White smoke coming from the exhaust could indicate that a head gasket has blown or there is a cracked cylinder head. Our technicians tell us that removal and inspection of the cylinder heads will be required to confirm a crack is present.
For the 2.3L 4 Cylinder and 5.0L V8 engine, the electrical ignition switch poses a fire hazard. An updated switch is available.
The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.
