I've looked through the discussion and done online searches using:garage-pro fan belt tensioner 5"-16". Nada. I even used the JC Whitney stock number. Anyone know where to source it? https://c34.org/bbs/index.php?action=dlattach;topic=3667.0;attach=1017;image
Mine was found on Amazon. The quality was good enough.
Try a google search for belt tension jack.
Porch : Contact one of your local auto parts stores - they'll probably have one!!
A thought
I picked mine up from MCS Tools. Here is the address for the tool itself. "Belt Tension Jack": https://www.mscdirect.com/product/details/35438209
Porch, did a search for " belt tensioner tool". Found some good pictures of home made solutions. One is really
simple to make, only need to grind the ends of the turnbuckle.
