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.
