Wells Maintenance Tutorial — Timing Belt
The timing belt is a critical component of the engine’s valve‑train system and serves as a drive element. Its function is to ensure precise timing of the intake and exhaust strokes by connecting to the crankshaft and operating at a specific gear ratio. During engine operation, the timing belt keeps the piston’s stroke, the opening and closing of the valves, and the ignition timing in perfect synchronization.
Most people are familiar with timing belts, but there’s still a small group who aren’t quite sure—or even unaware—whether their vehicle is equipped with a metal chain or a rubber belt.
