Why is my car belt making a squealing noise?
If there seems to be no fluid on the belts causing them to slip, the next thing to check is the tension on the belt. A belt that is either too loose or too tight will often slip against the pulleys, causing the squeal. While the motor is running, pour water over the squealing belt. It the noise stops, it tells you the belt needs tightening.
