This article is being republished in its entirety to clarify the issue of a possible oil leak from the flywheel bolt threads.

ISSUE: The threads of flywheel mounting bolts may be a potential leak path for engine oil.

ACTION: When removing or replacing flywheel bolts, install new flywheel bolts with pre-applied adhesive (E7TZ-6379-B) to eliminate any possibility of a potential leak path. The new bolts can be identified by six to eight threads with a silver color. Refer to the following procedure for service details.


1. When installing these bolts for the first time, do not apply additional adhesive to the threads.

2. Each time this new bolt or previous bolt (without pre-applied adhesive) is removed to service the flywheel, proceed as follows:

a. Clean the bolt threads.

b. Apply Thread Lock 262 (E2FZ-19554-B) to the threads.


c. Reinstall the bolt. Tighten to 47 lb.ft. (64 N-m).
