ISSUE: Engine coolant leaking at the cylinder head to engine block mating surface may be caused by broken cylinder head bolts.

ACTION: To correct this, install new cylinder head bolts (E7DZ-6065-A) and a new cylinder head gasket on the cylinder head that is leaking engine coolant. Also install new cylinder head bolts on the opposite cylinder head to prevent coolant leaks caused by broken cylinder head bolts. The bolts can be replaced one at a time without servicing the cylinder head gasket. Refer to the appropriate Shop Manual, Section 21-12 for removal and installation procedures.

CAUTION: DO NOT REUSE CYLINDER HEAD BOLTS. ONLY USE THE CYLINDER HEAD BOLTS E7DZ-6065-A OR E8DZ-6065-A. TORQUE TO 70-74 FT.LBS. (95-100 N-m).

NOTE: IF THE CYLINDER HEAD DOWEL IS DAMAGED DURING SERVICE, INSTALL A NEW DOWEL.
