Summary of Program Features
1. BackgroundOn some of the 1984-1985 Mazda 626 equipped with diesel engine, there may be oil leakage between the cylinder head and block or to the coolant passages at the high pressure oil feed hole, especially after repeated vehicle's cold start and heavy acceleration. This oil leakage was proved to be caused by premature deterioration of the cylinder head gasket.
The cylinder head gasket has been modified since February 1, 1985 as indicated in the Service Bulletin, Category 1, 011/85 dated April 18, 1985. In addition, the coating of the head bolt has been changed to secure sealing durability of the cylinder head gasket. However, this modification for the head bolt has not been applied to the Mazda 626 equipped with diesel engine for the U.S.A. as the production of this model for the U.S.A. ended on February 29, 1985 before this modification.
In order to assure customers' continued confidence and satisfaction with Mazda products, Mazda Motor Corporation has determined to institute the Program.
