If a squeak at the exhaust manifold to exhaust pipe seal (donut) is encountered on the above engines, it can be repaired by replacing it with a new seal, part number 25523858. This condition may be noticeable when shifting from park to drive or reverse. When replacing this part on a 3.0L engine, the adapter must be switched from the old seal to the new or you can order an assembly, part number 25523937, which includes both seal and adapter. Exhaust manifold and pipe flanges must be cleaned thoroughly to remove seal residue prior to installation of the new part.
Complete elimination of the squeak may not occur until the vehicle has been driven for several miles after the repairs are completed.
