Blew a head gasket in my 1995 Mercury Cougar due to a recall that was not performed by bell Ford on May 23, 2002 when the car was brought in for that reason only. When I contacted bell Ford and Mercury on March 27, 2003, neither will pay for the work that now needs to be done. I am now left without a car until it is fixed and a large bill to pay when this could have all been avoided if the recall was done when my car was brought in.

Ford/Mercury knew of the problem with the head gaskets on the 1995 3.8l v-6 engines and failed to send out any information in a timely manner. This means that there are quite a few cars that had already reached the mileage limit that they were willing to extend the warranty up to. We did not receive notification about the problem with the head gaste until after the car had over 100,000 miles on it. So what it boils down to is that we get shafted because of Ford.
Consumer stated that check engine light stayed on and RPM's jump from 2000 to 3000 causing the vehicle to loose all power. The dealer changed main sensor and the check engine light problem stopped, but RPM's problem continued. Dealer changed speed sensor and the problem still exists. Finally the head gaskets were replaced.
