Squealing belt

Sometimes during the engine operation some unusual sounds may be heard. Very often the problem is connected with auxiliary drive belts. Such squealing sounds of the belt may be caused by its wear or contamination. In the course of time an old belt shrinks and loses its elasticity which can cause micro-cracks clogging up with accumulated sediments. The squealing sound appears due to slip of the belt on the pulley.

The belt has to be at the right tension to function properly. If the belt is too tight it will create extra resistance in the engine. Worn out pulley bearings could cause the belt to stretch or break quickly. Your engine belts make a screech or squeal noise usually because the rubber belt is slipping on the metal pulley. The belt may be slipping due to improper tension or because it simply has gotten old and the surface has become glazed, cracked or brittle.
