A/C belt Q?

[kansas-ix]

Ok I put the right size belt (890) on my car last week, and it is already loose and making noise, as far as I know there is no way to adjust the belt correct? Reference the car is a 91 318i, M42.

So my main question is the belt loose because I bought a shitty O'Reilly belt?
or should I try to jam a 888-889, on there, so when it loosens up it will still be tight?

realoem says the belt is an 885, im pretty certain theres an adjustment, how did you get the belt on?

I took the compresor off to get it on and it was still a bitch!. I had to stretch the shit out of a 890. Threre is the main central v belt area, then to the lower there is a rubber pulley but I don't see how you adjust it, the owners manual says 890.

There has to be an adjuster, if anyone knows how to adjust a a/c belt chime in as it is hot as fuck in KS.

I million sweat beaded thanks

ive never adjusted or replaced ac just remeoved it but the compressor mount bracket bolts should be the adjustment if there isnt any other way of doing it
