A replacement-style timing chain retainer tool for mechanics servicing GM engines in the 2.8L, 3.0L and 3.6L sizes, used across Cadillac, Chevrolet, Buick and GMC models. It holds the timing chain in place during repair or replacement work so timing stays put while the job is done.
The retainer is made from a high-strength metal for wear resistance and stability in a busy workshop. The listing gives the part reference EN-49982. It is intended to be fitted without removing the whole engine, which can cut down on labour time. Check the compatibility details against your vehicle before buying.
