This is a $269. 99 part not to mention the gaskets, anti-freeze and labor involved to fix. I feel this is a manufacturer defect and I should be reimbursed for the cost of the part at the very least.

Failure Date: 08/08/2004

My 93 year old aunt paid $950. 00 to have the manifold repaired 8/6/04 on her 1997 Mercury, and now Ford does not want to pay her, what a bunch of crap. My uncle came back from wwii bought a new Ford or Mercury every 2-3 years for 50 years, what gratitude. I see why Ford and gm is going down the tubes. It excluded cars that were more than 7 years old when they experienced manifold failure. Based upon that 7-year period, we believe that all 1996 and 1997 cars ( and many 1998's ) that failed in 2004 - 2005 (approx. ) or haven't yet failed, were denied coverage. The concept adopted in the settlement appeared to be that "civilians" should not get warranty coverage longer than the 7 years that was given to those cars covered by the 1999 owner notification program. ( one of the lawyers told us that they settled for the 7-year coverage because, during a court hearing, the judge had said that she was not likely to grant coverage longer than what the "fleets" got. ).
