Does anyone know what size belt I need to bypass the A/C compressor? I've thrown three belts in as many weeks due to what I believe is the compressor locking up. I just need to bypass this until I can afford to replace the compressor.

Hello,

Since all these vehicles come with factory A/C the catalog does not provide the belt size or part number.
You can use a string or rope and route around the pulleys as it should go and simply measure it.
Make sure when you do this there is no interference with any pulley or component for the routing. The tensioner pulley looks very closely if the compressor is bypassed.

Let me know of any questions.
Thank you

Instead of giving someone the actual size that they would need for the serpentine belt to bypass the AC unit, you dump it on them instead of actually having an answer. And there's still no answer here even from the owner which is no good.

Correct, this is because they dont make the size from the factory, you need to find the size out ourself. Of course once people do they just leave and not give the size. That's people.
