Hello,

Okay, so how you do this is take a ball of twine and wrap it around every component that the new serpentine belt is going to drive, leaving out the A/C compressor. When you reach the first end of the twine, mark where they meet and then measure the distance in millimeters. If using a gates belt count the number of pulley grooves on your crankshaft and that is the first number, followed by the length. For example if your crankshaft pulley has 6 ribs and you wanted a 1130 mm belt then you would need a k06 1130 serpentine belt. I hope this helps.

Thanks,
Alex
