Dayco® developed the first POLY-V BELT® or Multirib belt for the Ford Mustang in the USA in 1979. Today as in 1979 this belt sets the industry standard.

• Better belt to pulley contact - for less slippage than conventional V-belts.
• The Grooved Design - provides flexural stress relief for increased flexibility in both normal and backside bending. The grooves also render the belt less susceptible to environmental factors such as dust and splash induced slip.
• Rubber Impregnated Fabric Backing - that maximizes load carrying capability and minimizes noise often associated with competitors belts.
• The cord is saturated with a specially formulated treatment that ensures length and belt stability for the life of the belt.

Eliminate the need for matching and allows for controlled slippage in overload situations, such as when an A/C compressor engages.

Cracked or split - check for cracks or splits on the bottom sides of the belt as it flexes.A cracked and or split
belt can fail at any time.

Glazed - A belt with slick,hard sides doesn¡¯t function
properly.This can cause a radiator or other components to overheat.

Grease - Grease build up causes the belt to soften,deteriorate and fail.
Ribs chunk out - This belt can fail at any time.

Peeling - When the undersurface of a belt peels,it becomes uneven,causing rough operation and failure.
