Squeaky noise from Evosport pulley?

2058 15
I have evosport pulley for about 6months and last month or two I experienced a squeaky noise from the engine bay especially in the morning at cold-start. Some advised a incorrect size belt, but I want to hear from others members who have pulley installed whether they experienced the same. I never heard anyone complaint about a squeaky noise before, or just what an unfortunate for me.:sad3: Any feedback would help. Could the belt be slipping out under a heavy load/high RPM? I don't mind the squeaky noise that much instead, if the belt could slip out, that will concern me the most.

Two things could be happening here.

1. Pulley is not lined up properly with the others. This will cause the belt to slide sideways and thus squeak.

2. The Pulley's bearings could be dry (No grease) and this could cause a squeak.

Both pretty unlikely, but something to think about seeing I have had this same issue on my cobra while replacing just about every pulley on the car.

Thanks for the advise.

My vote is a slightly offset pulley. I would remove inspect and reinstall the tension and idler pullies.

Finally has a friend measured the belt size between Rogue and Evosport. They have the same diameter on Pulley but the evosport's belt is about 0.5cm bigger. Would that be a problem?

No, The tension pulley will take care of the slightly larger size. The noise could be coming from any of the pulleys but if you know for sure it is coming from the crank pulley it may be slightly out of line. Maybe it could be coming slightly loose? Not sure.
