What Are the Consequences of Incorrect Timing Belt Installation?

[Iris]

If the timing belt of a vehicle is installed incorrectly, it can lead to two scenarios: 1. The first scenario: If the timing belt is installed one tooth off the correct timing point, it will cause the engine malfunction light to illuminate, difficulty in starting the vehicle, and the engine control unit will report a timing-related fault code. 2. The second scenario: If components such as the timing belt, timing belt tensioner, or timing belt tensioner pulley are not properly installed, or if there is a significant misalignment in the number of teeth, it can result in the timing belt breaking. This will prevent the camshaft from operating normally, leading to a collision between the valves and pistons, causing severe engine damage. The only reliable solution is to strictly follow the manufacturer's standards and requirements when replacing the timing belt to avoid unnecessary losses.
