“I understand there was a class action suit due to a faulty intake manifold on many ford cars with a 4.6 liter engine. I or my kids have owned a 1997 Mercury Cougar since new. Recently this car which had been in storage for several years was given to my son who is laid off and attempting to complete his bachelors degree. I spent money to repair sensor, freezeplug and he put new tires on this car. …”

“My vehicles became totally disabled on a very busy highway with heavy after hours rush hour traffic. The manifold which is made of plastic broke were the coolant temperature sensor was built in, I also noticed that a few sparkplugs were flooded with coolant. I found out that there was a lawsuit on these vehicles but no one knew about it and only fleet vehicles were covered and not civilian vehicles. I wonder if there is any chance for me to seek a dealership and get reimbursed for these damages.”

“I have a 1997 Mercury Cougar. After seeing a low coolant light, and stopping the car, I opened the hood and had coolant everywhere! The car was towed to a repair shop and I was told it was a cracked intake manifold. After further research I have found this is a continual problem with ford produced automobiles.”
