## Description

GM Genuine Parts Engine Timing Belt Tensioners are designed, engineered, and tested to rigorous standards, and are backed by General Motors. They help keep constant tension on the timing belt to help prevent the engine from jumping time. They also help keep the valve train and timing in sync. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Review: Cost and delivery time - I was impressed with the communication from the time of purchase to the delivery. It was affordable and received in good condition ahead of the expected date.
Review: 2.8 liter Duramax Diesel - The part works just fine. Bought this as part of the timing belt job on a 2017 GMC Canyon equipped with the Baby Duramax diesel engine. If this is a DIY job, I highly recommend buying the timing kit from Sasquatch Parts.
