Detailed Description

Dayco 15400 is an accessory drive belt engineered for vehicles that use a narrow V-belt profile in accessory drive applications. The top-cog construction helps the belt conform around pulleys, which is important in systems that drive the alternator, power steering pump, fan, water pump, or air pump. This belt is listed across many fitments, including Volvo 740 and Volvo 940 alternator and power steering applications, as well as Chevrolet Caprice, Camaro, and Firebird power steering applications.

This part cross-references Gates 7400 for the same application. If you are searching for a Dayco 15400 belt for a Volvo 940 alternator or a Chevrolet Chevette fan and alternator setup, verify the position and notes against the vehicle listing before ordering.
