How often should the Swift timing belt be replaced?
2 Answers
The Swift timing belt should be replaced every 100,000 kilometers. Below is a partial introduction about timing belts: 1. Definition: The timing belt (Timing-belt) is an important component of the engine's valve system. It connects to the crankshaft and operates at a specific gear ratio to ensure the accuracy of intake and exhaust timing. 2. Function: The timing belt plays a connecting role. The upper part connects to the timing pulley on the engine cylinder head, while the lower part connects to the crankshaft timing pulley. The timing pulley is connected to the camshaft, which has cams. The contact point is the small rocker arm, which generates pressure through the power transmitted by the timing belt, thereby lifting the valve.
I've been driving my Swift for over ten years, and timing belt maintenance is a big deal. I remember the first replacement was at 75,000 kilometers, and the manual recommends changing it every 80,000 kilometers or six years. If you delay too long, the belt can age, crack, and snap, potentially causing engine valve damage, which could cost thousands to repair. A friend of mine waited until 90,000 kilometers to replace it, and the belt snapped on the highway, costing over 10,000 yuan in repairs—a huge loss. So now, I check the belt condition every five years or around 70,000 kilometers, looking for surface cracks and tooth wear. Stop-and-go city driving accelerates aging, so you need to be more diligent. The replacement cost isn't too high—an OEM belt plus labor is only about 700-800 yuan. As an experienced driver, I suggest not exceeding 80,000 kilometers for replacement—safety first, peace of mind, and cost savings.
