Switch off your engine and permit it to chill . depress on the highest of the belt. If it’s so loose that you simply can push it down by quite one centimetre (a half inch), it must be tightened or replaced by a mechanic. However, you’ll temporarily silence the squeals.
Use a knife to chop a skinny slice from a bar of soap. Rub the soap on the inner surface of the rush the maximum amount of its length as you’ll reach (having a skinny slice of soap helps you reach further).
Start the engine and check for squeals. Repeat the method if necessary.
