Do you have an image of the serpentine belt routing for 91 jeep wrangler 2.5l

Google it go to imaged

There should be a sticker in the engine compartment that shows the routing and you should be able to hold the tensioner back with a 3/8's ratchet with a long handle.

this is for a system with a/c. If you don't have a/c let me know and I will get you the correct one but i'm sure that you have a/c and power steering.
