1990 Ford Thunderbird SC Problems

Coolant 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.

Battery Light Due to Damaged Alternator Connector

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.

Clunk and/or Rattle Due to Worn Inner Tire Rod Ends

While steering, if you hear a clunk or a rattle, or if you experience premature tire wear, this could indicate the inner tie rod ends are loose or worn and will require replacement.
