GM Timing Chain Camshaft Holding Tool Retaining Set for Cadillac Buick Saturn Pontiac Chevrolet

Absolutely a must-have tool for doing 3.6l GMC timing chains! Eliminates ANY chance of a cam/crank correlation code. Makes doing the actual timing part of the job effortless. Now, if they'd just have made the trucks they came in (Acadia, Traverse, Enclave, etc) user friendly at all...

These lil guys made it so much easier to swap the timing chains on my cts. These allow you to service all 3 chains with only one set of timing marks. The dot on the crank sprocket is lined up with the dot on the bottom side of the oil pump. Once that’s done you use the “straight flats” tool on the drivers bank and the “angled flats” tool on the passenger side and that’s it no need for the 3rd tool.I used the Mellings 3.6 timing guide on the ol YouTube as a guide and it worked flawlessly.

If you are going to replace timing chains on a 3.0 or 3.6L V6, get these cam locks. Don’t pay attention to the videos showing changing half the chains in phase one timing, then the other half in phase two timing. Set the engine to phase one timing, slide on the locks, replace all chains, aligning the timing marks. Done.

Did good for the job would use them again

we like them

I used this tool to do the timing on my 08 gmc acadia. Its possibly to do the job without the tool. However, why run any risk at all? Put your mind at ease and use it as a spot checker just to be absolutely certain. I would definitely buy again

It did it's job a couple of times now it's worn out.
