Timing belts come in various tooth configurations, and the choice of a 129-teeth belt often reflects optimal design for specific engine setups. The number of teeth determines the belt’s length and, subsequently, how it interacts with the pulleys designed to accommodate it. An exact match in teeth count is crucial; too few or too many teeth can lead to improper timing, which can cause severe engine damage.

The new serpentine belt is essential for maintaining engine performance and ensuring that key components like the alternator, water pump, and air conditioning compressor function seamlessly. Unlike older multi-belt systems, serpentine belts use a single loop of the rubber ribbed belt to drive multiple accessories, making them more efficient and easier to maintain.

If a timing belt breaks, it can cause severe damage to both the engine and the surrounding components. In interference engines, a broken timing belt may lead to the pistons striking the valves, resulting in bent or broken valves, damaged pistons, and potentially a complete engine overhaul. Thus, the importance of maintaining the timing belt set cannot be overstated.

1. Serpentine Belt Most modern vehicles use a single serpentine belt that integrates all the functions of the accessories mentioned above. Its design allows it to be more efficient and take up less space than multiple separate belts.

The Myvi 1.5, a popular model amongst Malaysian drivers, relies on its V-belt for optimal operation of key engine components. In this model, the V-belt connects the crankshaft to various accessories. An effectively functioning V-belt leads to
