Can anybody tell me the proper fan belt needed for running the ac compressor, there are 2 different ones listed at the auto parts store? I'm not sure how to tell which one I need!
​​​​​​ Thanks in advance!

 

buy both of them, and return the one that is the wrong one. as long as you do NOT install, you can return>>>>if not, find another auto parts place.

Or you can go to Rockauto dot com, they just have one listed for the a/c compressor

 

Measure the route and find a belt that matches the length the closest.

 

It depends on several other things. Type of AC compressor and if there is power steering.

Like said, Measuring is the best. Adjust the pulley to about middle and then take a piece if string and put around the pulleys. Take a tape measure and measure the string. Then when at the store get what fits.

RockAuto will sometimes show variations and describe what options they fit.
