The PK belt is a type of drive belt that transmits power from the engine to various components within the vehicle, including the alternator, power steering pump, air conditioning compressor, and water pump. Unlike traditional V-belts, which are usually designed for one single purpose, the PK belt features a series of grooves along its length, allowing it to effectively grip multiple pulleys at once. This design not only improves efficiency but also saves space and weight in the engine compartment.

Ci sono alcuni segnali che possono indicare un problema con la cinghia di distribuzione. Uno dei principali è un rumore di clic o di sfregamento proveniente dal motore. Questo può essere un'indicazione che la cinghia è allentata o che sta subendo un'usura anomala. Altri segnali possono includere perdite di olio nel motore o vibrazioni insolite. È fondamentale prestare attenzione a questi segnali e far controllare il veicolo da un meccanico qualificato se si notano anomalie.

A timing belt is a reinforced rubber belt that connects the crankshaft to the camshaft in an internal combustion engine. Its primary function is to synchronize the rotation of these shafts, ensuring that engine valves open and close at the correct times during each cylinder's intake and exhaust strokes. A double timing belt, as the name implies, features two sets of teeth or tracks, which provide improved engagement with the gears it drives. This design enhances stability and reduces the risk of slippage, which is crucial for maintaining optimal engine performance.
