What 1996 Mercury Cougar owners say
Engine & cooling all 21 →
I just purchased vehicle from used car lot. During my 3 mile trip home the car over heated and water vapor was coming in through air conditioning vents. When I stopped at my home, I could see steam coming from inside engine. When I opened the hood, I found that there was crack in a plastic part coming directly off of the engine block to a coolant hose. I went to several auto parts stores to identify the part and found it was a crack in the intake manifold water cross-over jacket causing coolant leak. The stores did not carry a replacement, so I called the Ford dealership. Ford does have a replacement part, actually they redesigned the whole intake manifold because of their poor design error. They also had extended the car warranty to 7 years to replace this part if/when failure occurs. …
Check for coolant leak at intake manifold. Replaced intake manifold. There were regular oil changes and tire rotation. The engine light had come on, and the coolant light would come on and off. The dealer had to replace the engine sensor light and added a cup of water. The consumer's son in law was driving the vehicle and white smoke coming from under the vehicle, the rubber strip on the inside of the vehicle was coming off, the right rear trim panel coming loose, the brakes made rubbing noise intermittently, glove box door won't shut, the air bag would rattle, the right front door rattled while the vehicle was in motion, and the door switch trim panel was discolored.
