Vehicle Fitment Guide

 

For the timing chain kit in this engine rebuild kit, there may be a discrepancy for vehicles built on dates that borderline the change-over of the design of the timing chain. We cannot guarantee what kit you require if this applies to your vehicle. You can confirm by removing one of the cam covers and inspecting the chains that run over the cam gears.

 

Caution:

Once assembled, the timing chain tensioners need to be fully released to maintain adequate tension. Simply pulling the pins is not enough. All tensioners must be pressed in by hand for the internal mechanism to fully pop out and operate effectively. Following this, the motor is to be rotated by hand one full revolution in a clockwise direction to ensure all parts have been fitted correctly. Failing to follow these steps will result in a noisy timing chain upon start up and will require the motor to be disassembled again to access the tensioners.

 

Notes:

Missing Part, no customer support.
Missing the bolt that attaches the base to the center post. We contacted the vendor and they responded, "We want to assure you that all our parts undergo rigorous inspection and careful packaging before shipment. If you could kindly check the box again for any missing parts, it would be greatly appreciated. Best Regards Yaheetech Customer Service Team" Really, like we didn't checked the box? Responded back to the vendor that we tore the box apart, no bolt. They have gone silent. Update, vendor has offered a partially refund, guess I'll head to Home Depot and look for a replacement bolt. What a pain. Went from 1 to 3 stars for at least contacting us.
