Caution On Cylinder Head Bolts On 1982-83 GM (Pontiac) V6 Diesel Engines
The Torx(R) drive cylinder head bolt (part no. 22515533) is used in 3 locations on each cylinder head in the subject engines and is installed under the pipe plug as shown. Some of these bolts may have a washer face thickness of approximately 2.0mm (.080). If work is done on this engine that requires the removal of these bolts, do NOT reuse them unless the washer face thickness is a minimum of 2.8mm (.112).
Bolts that do not meet the minimum thickness should be discarded. Bolts with the thicker washer face are available under part no. 22515533.
