1990 Mercury Cougar Problems

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.

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.

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.

1990 Mercury Cougar Reviews

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.
