Thread: Engine pulley list and belt size chart

Cool...that question is better suited in a new thread by you.

Just as a heads up, Fullsize IC +3.8 pulley needs a 695 belt, not a 685. It would never fit.

I stepped up to a larger s/c tensioner pulley for more belt wrap on the s/c. 38001 Gates pulley on my 04. It is 3 inches diameter and all other specs are the same as the stock 38006. It will kiss the s/c idler pulley until you get the belt on and it gets pulled away. I found going .2 inches down on pulley size and going to the larger tensioner pulley balanced out perfectly for belt size.

Seems like the pulley picture is no longer functional. So I am posting this picture for future needs.3800pulleys.JPG
