A poly V belt, also known as a multi-ribbed belt, is designed with multiple grooves running along its length. This design allows for a larger surface contact area between the belt and the pulleys it engages with, leading to improved grip and reduced slippage. The poly V belt is often made from high-quality materials like neoprene or EPDM rubber, which provide excellent flexibility, durability, and resistance to temperature fluctuations. The 135 in the 135J6 designation refers to the belt's overall length in millimeters, while J6 corresponds to its specific profile and rib design.

The primary purpose of the timing belt is to ensure that the engine's valves open and close at the proper times in relation to the position of the pistons. This synchronization is crucial; if the timing belt fails and the camshaft and crankshaft fall out of alignment, it can lead to severe engine damage. Such a malfunction could cause the pistons to collide with the valves, resulting in bent valves, damaged pistons, and potentially, a catastrophic engine failure.
