I recently noticed a squealing noise from around the fanbelt area after starting the car. There is no squeal from the belts if I rev up the engine so I do not think the belts are bad. I oiled the rusty bolt that holds the main pully on the fanbelt, but the noise still persist. Could a particular pully need replacing? I think there are 3 pullys. Since I bought the car two years ago, I have no idea if the belts have been replaced. The car has only 45K miles on it and is a 2001. Any guess as to what it might be and is there anyway that I can check it out myself before taking the car to a technician??
