Designed for OE multiple groove pulleys, Dayco® Banded V-Belts are specifically designed for applications where original equipment pulley drive design requires the use of two v-belts joined together by a tie band. The belt's Raw Edge® construction, 3-ply laminated fabric and neoprene compounding ensures superior gripping power while the bottom cog construction provides extreme flexibility and cooling. By combining two belts utilizing the tie-band process, the Dayco® Banded V-Belt greatly reduces the tendency for single belts, when subjected to fluctuating load tensions, to come off or turn over in multiple belt pulley drives.

Customer Questions
Can a serpentine belt cause smoke?
Yes, a serpentine belt can cause smoke. A serpentine belt is an essential component of a vehicle's engine system. It drives various accessories such as the alternator, power steering pump, water pump, and air conditioning compressor. If the serpentine belt becomes worn, damaged, or misaligned, it can cause friction and generate smoke.
Why is my serpentine belt squealing?
The serpentine belt can squeal due to various reasons, including tension issues, worn-out belt, or a problem with the belt's pulleys.
Is my serpentine belt too tight?
If your serpentine belt is causing issues like excessive noise or accelerated wear on the pulleys, it may indicate that the belt is too tight.
Why did my serpentine belt come off?
Serpentine belts can come off due to factors such as belt wear, improper tension, misaligned pulleys, or a faulty tensioner.
