ISSUE
Some engine assemblies with aluminum cylinder heads repaired in-vehicle have been found to leak coolant and/or oil from the cylinder head gasket area due to particle contamination or scratches and dents at the head to block mating surfaces.
ACTION
Refer to the following Service Information for recommended gasket sealing surface preparation procedures. If the engine diagnosis points to a faulty head gasket (leaks oil, leaks coolant, oil or coolant contamination, or air in coolant), thorough cleaning procedures are necessary for a successful head gasket repair. Diagnosis and post-repair confirmation can be done successfully utilizing leak detection methods such as a black light dye process.
