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.

Exhaust & Emissions -- Verified

The Check Engine Light can illuminate with codes due to the lack of EGR (exhaust gas recirculation) flow caused by the intake manifold passage plugging up with carbon and oil. The EGR valve has to be removed and the passage cleaned thoroughly. Partial restriction of this passage can cause Smog test failures for the NOx emissions without causing a drivability symptom.

Engine -- Verified

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

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.

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.

I need help on find air condtioner filter on it recharged it but the filter is plug can't find it does anyone know where it is.I love my car too.

I just got a used 1993 Cougar & it was sold to me by the 1st original owner who has kept it in meant condition with only 95.000 mile on it. It had been kept in a garage with a cover over it so it's nice inside & out. But it has a few problems with it & I'm not sure how to get it fixed. The drivers side window doesn't work & the gas gage is stuck on full so we have no idea how much gas is in it. Because the car is so old I don't even know if it's possible to get the window & gas gage fixed or not but it's a real deal breaker on whether or not I keep the car because I have to have those things fixed. I just don't know where to take it to get it fixed or buy the parts & have it fixed.

I owe a 1996. And it's a good sturdy car. But I just had to replace the whole transmission, new battery, new brakes and 4 new tires. I only had it for about a year, and the older women who had it before me only drove it around town. I have already put more into it then I paid for it. Although I have bought a new car, I still keep this one for emergencies. Since I got the repairs, it doesn't run the same anymore. It's a good car, just not my first choice.

It's the light switch itself that you pull out to turn your lights on. Change it out from a junkyard one and you'll be fixed.
