k so past few days my car has been making a weird noise when the ac is on like a slight whine slight grinding sound real annoying. around 2000rpm.... it only makes the noise when the ac clutch is engaged.... i want to snug everything but im not sure how to tighten or loosen the ac belt. is a b16 in a eg 4dr with ps... if anyone has pics on what to do it will help greatly.... i do not think its the belt bc its dead quiet when the ac is off...
