Why Do My Belts Squeal at me. There are many different types of belts on vehicles today. The older term for the belts we are discussing is “fan belts” or “V belts” as three or more v shaped belts moved fans etc. in the engine. Today the belts are called “serpentine belts” as they serpentine around many different pullies. A good generic term to use now is a “drive belt” which covers all the different types.
