Shemy 0 Report post Posted January 9, 2013 I've got a 1989 BMW E30 325I with an M20 engine in, the AC doesn't have a belt on at the minute. Does anyone know the size of the belt? I've got two sizes but I'm not sure which one... 12.5 x 810 - P/N 64521706826 or 12.5 x 823 KLIMA P/N 64551722990 Anyone got an idea on which one to get?

yng_750 247 Report post Posted January 9, 2013 yea a 13 x 810 should be fine Its a V belt so a larger section by .5mm wont bother it. And there should be plenty of adjustment for either length to fit. If you go into supercheap or repco the part number will likely be in the format 13A810 or 13A0810 but you could go anywhere from 790 up to 840 and it should fit. Bit of trial and error if they dont have the right one on the shelf Quote Share this post Link to post Share on other sites

e30ftw 402 Report post Posted January 10, 2013 You probably just need a spanner to loosen the adjuster bolt, slip on the belt then tighten it up to adjust Quote Share this post Link to post Share on other sites

hotwire 352 Report post Posted January 27, 2013 ^^^^ If the A/C belt runs behind the others - then yes Quote Share this post Link to post Share on other sites
