The PK belt, also known as a serpentine belt or poly-v belt, is a type of belt used in various car models, including those manufactured by Renault. This belt is designed with a series of grooves that help it grip the pulleys of the engine components effectively. It drives multiple accessories, including the alternator, power steering pump, water pump, and air conditioning compressor. The PK refers to the belt's profile shape, which is designed to fit specific pulleys within the engine compartment.

A timing belt is a rubber belt that synchronizes the rotation of the crankshaft and camshaft. This coordination is vital because it ensures that the engine’s valves open and close at the proper times in relation to the position of the pistons. If the timing belt fails, the consequences can be catastrophic. An engine may misfire, and in the worst-case scenario, a broken timing belt can lead to serious engine damage, including bent valves, damaged pistons, and in some cases, a complete engine failure.
