I have recently converted from P2 850cc stock engine to D L502S JB-JL 4-cyl turbo engine. But, I have a very annoying problem with the accessory AC belt for the L5 aircond compressor system. The compressor works fine (it immediately cools the air within a few seconds..it is really cool) but the belt produces a squeling sound sometimes and it looks a little bit loose. I had asked a mechanic to tighten the belt but after one day, it is loose again.

Is there a problem with the belt or the compressor mount bracket? Currently, I use Bando Power RPF belt model no 2295. Based on the link below, it looks like I am using the wrong one...From the table list, it suggests AC belt type K295...sigh

I need some advice for the right AC belt model to use or how to improve the compressor mount bracket if it is the case...
