I am replacing the belts on my 2010 Escalade and when it came time to replace the stretch belt I found I did not have a large enough socket to turn the crankshaft. The largest I had was 13/16".... I'm leaning toward it being 1", can anyone confirm that for me? Thanks.

Your turning the crankshaft to replace a belt?

Yes, there are two belts on the 2010. A serpentine belt and the A/C belt which is a stretch belt. In order to get it on the pulley you need to use the installation tool by placing it on the crank pulley and turning it slowly to seat the belt properly on the pulley. Here's a video that demonstrates how the belt is installed.

Ahh I was not aware of this. I hv seen and worked on "stretch" systems. I never thought GM would go to it though.

No one has done this and can tell me what size socket it is? I guess I'll have to go buy a few sizes.

Go to the parts store and see if they have one to loan you. I've done that before with tools that wouldn't be used often. I know Oreilly's will loan tools.
