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.

Engine Stalling and/or Hesitation on Acceleration due to Faulty Idle Air Bypass Valve

If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.

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.
