Description of Change: A new plated bolt with increased corrosion resistance has replaced certain bolts on engines that are equipped with rigid wiring harnesses. The bolt is used to install the end caps on the rails. The bolts are also used to assemble the two halves of the covers for the ECM connector.
Adaptable To: The former bolt that is not plated is 8T-9006 Bolt. The new bolt that is plated is 311-3922 Bolt .
The new 311-3922 Bolt is adaptable to the engines that are listed above. The new bolt is effective with engines that are built after 23July 2007.
