A ribbed belt is a power transmission belt featuring lengthwise grooves. It operates from contact between the ribs of the belt and the grooves in the pulley. Its single-piece structure offer an even distribution of tension across the width of the pulley where the belt is in contact, serpentine drives (possibility to drive off the back of the belt), long life, stability and homogeneity of the drive tension, and reduced vibration.

• Its excellent bending and straightening ability makes it suitable for small belt wheel and inversed
• Good transmission efficiency
• Low noise

If a serpentine belt breaks, a car won't be drivable and will have to be towed. If the engine runs without a serpentine belt, it might overheat as the water pump will no longer work. A broken belt can also damage other parts. We have seen broken radiator shrouds and ripped coolant hoses that were damaged by a ripped belt.

Symptoms of a broken serpentine belt include loud slapping, squealing or knocking noises coming from under the hood. The battery-shaped charging system warning light might also come on because the alternator will stop charging the battery. If a car has a hydraulic power steering pump, the steering will become stiff.
