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.

1991 Mercury Cougar Problems
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.
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.
The intake and valve cover gaskets may leak oil.
For the 2.3L 4 Cylinder and 5.0L V8 engine, the electrical ignition switch poses a fire hazard. An updated switch is available.

1991 Mercury Cougar Reviews
My dad was the second owner. I bought it from him at about 85,000 miles. The doors are long and heavy and after many years, they will sag. I have shimmed mine up and everything is fine. Brakes are good, but mine only has drums on back. It has the 3.8L and I replaced the head gasket twice by 150,000. Ford's 3.8L had a head gasket problem no matter what they were in. I finally replaced it with a 98 Mustang 3.8L. After 97 they had redesigned the decks and they don't have the problems anymore. It is bulletproof. It has over 250,000 with the original transmission and 7.5 rearend. Put an oil cooler on any Ford with an AOD. It used to slip out of overdrive when it got hot or when I drove it hard (all the time). Not a problem anymore with an oil cooler. It still has the original exhaust pipes. I put new catalytics on it several years ago. AC was originally R-12. Works fine with R-134a. Just flush it, evacuate and fill it. Heater cores are problems and very difficult to change. It is buried under the dash. I have been putting off doing it again. Get one from Ford or somewhere really good. Not going cheap this time. The suspension and steering is a lot of what set the T-birds and Cougars apart from every other American car in their day. Front and rear independent suspension with unequal length control arms (or short-long as they call it these days). It is the reason I love these cars.
This is my second Cougar (my daughter totalled my first), and I will never drive anything else. With all the talk of ergonomic design in the new cars (upwards of $30,000), they could all take a design lesson from the cabin of the amazing Cougar!!! Looking forward to someday owning the 30th Anniversary Edition.
