A fan belt adjuster, commonly referred to as a tensioner, is a device that maintains the proper tension on the fan belt. It ensures that the belt remains adequately tight to prevent slippage during operation. Proper tension is essential not only for the optimal performance of the accessories powered by the belt but also for the longevity of the belt itself. If the fan belt is too loose, it can slip off the pulleys, leading to a complete failure of accessory operations, while a belt that is too tight can cause excessive wear on both the belt and the components it drives.

The primary function of the internal timing belt is to synchronize the rotation of the crankshaft and camshaft. This synchronization is essential for the timing of the engine's valve openings and closings in relation to the position of the pistons. When the crankshaft rotates, the timing belt transfers that motion to the camshaft, which controls the intake and exhaust valves. Proper timing enables the engine to run smoothly, improve fuel efficiency, and increase overall performance.

The internal timing belt is a critical component of an engine's internal mechanics, playing a vital role in ensuring that the engine operates smoothly and efficiently. It is an essential part of the engine's timing system, which coordinates the movement between the crankshaft and the camshaft. This synchronization is crucial for optimal engine performance, as it guarantees that the engine's valves open and close at precisely the right times during each cylinder's intake and exhaust strokes.
