My A/C Compressor is locked up. I put a new tensioner pulley on due to one on it being destroyed and found compressor locked up. I want to bypass the compressor all together but can’t find a video on that particular motor to know what the belt length would need to be. With this many miles on it I only need to get back to Iowa from Missouri with the vehicle and decide from there if want to replace the compressor. Thank you for your time.

Hello,

Since these vehicles came with factory A/C, the catalog does not provide the belt part number or size.
To find out what size belt is needed, you will have to route a string/rope around the pulleys by passing the A/C compressor. Then simply measure the string to get the belt size.
As long it does not interference with any other pulley this method will help you determine the belt size.
