Dayco 15645 accessory drive belt for the 1975-1978 Dodge Charger V8 6.6L and other vehicles carries engine power to the belt-driven accessories.
Squealing, cracks, fraying or a shiny glazed surface can mean a belt is worn. A weak tensioner, a worn or misaligned pulley or a fluid leak onto the belt can produce some of the same noises, so find out which one you have before buying.
This belt is listed for a wide range of Dodge, Chrysler, Plymouth and Oldsmobile models, led by the 1975-1978 Dodge Charger V8 6.6L, the 1975-1977 Chrysler Town & Country V8 6.6L and the 1967-1968 Chrysler 300. It is a direct-fit replacement for these vehicles, and all three take two.
