Multi rib belt or also called as serpentine belt is a drive belt that is primarily used to transfer the torque from the engine to its external parts such as the water pump and ac compressor. It is called as serpentine belt because of the way it is being mounted on the pulley on the engine compartment wherein it fits snugly like a snake. This multi rib belt has a wider belt compared to an ordinary v-belt, significantly eliminating the use of multiple thinner belts to promote higher tension capabilities without stretching. When you gain a higher tension rate, this increases the life of the belt and reduces occurrence of slippage. All these gains on your vehicle will also result to lesser load that the engine needs to carry and more horsepower available to drive your wheels farther. Multi rib belts are also easier to maintain and replace as it eliminates the use of two or more belts, thus there's only one that needs to be changed. Nonetheless, inspecting the condition of your belt in regular intervals would be necessary as to recognize any worn out part earlier. It is also advised that replacement of your stock multi rib belt must be after every 50,000 miles of mileage as this is the time that the belt starts to slip. Excessive belt slippage can result to lower tension rate, causing the engine to drag higher load capacity. This will also be one of the reasons why those external parts of the engine fail prematurely.
