1990 Mercury Cougar Problems

Electrical & Lights -- Verified

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.

Engine -- Verified

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.

Suspension & Steering -- Verified

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.

Engine -- Verified

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.

Purchased this car used (68,000 mi). Although it is an older car, it was well maintained. Thus, it drives like a new car. Some issues I have are:
1. retrofitting A/C.
2. none of the upgrades like current vehicles.
