Whats up guys, i just got my rsx-s runnin a couple weeks ago. I aquired it with a locked up engine and rebuilt it. Well i decided not to reinstall the a/c when i put the motor back in and searched for a while on which belt size to get and came up with no luck at all.
So i figured it out myself and found a 6 rib belt thats been working great.
Its from autozone - Duralast 537k6 is the size
That is for the k20a with power steering but no a/c
A k24 would be different due to different crank pulley size.
Just wanted to share this info with this site for anyone that wants to take their a/c out!
