Hi! Its me again. This time I would like to ask what is the problem with my engine because when it is idle the engine sound is smooth, then when I rev it up there is a squeaking noise. What may cause such noise?
check the belts visually and for proper tension, if they appear ok, have someone rev the engine to the point where it normally squels and than spray a small bit of water on the belt, if the noise goes away the belt is bad
