if the chirp gets higher is increase in throttle. spray the belt with belt dressing. if that is not the problem, take the belt off, restart the motor after it cools. if the sound is gone then the problem is in one of the pulleys. my first guess is the tensioner. I had a similar problem and tighten the tensioner bolt and the problem was fixed. the problem was cause by take the belt off when it was replaced I didn't tighten the mounting bolt on the pulley. With belt off it should help in the trouble shooting. hope it helps. gotta love a rover. duboff
