How to install timing belt
The timing belt is a vital component in the engine, responsible for coordinating the synchronous operation of the crankshaft and camshaft. If installed improperly, serious damage to the engine may result. This article will detail the timing belt installation steps, precautions, and recent hot topics related to car maintenance.
1. Timing belt installation steps
| step | Operating Instructions |
|---|---|
| 1. Preparation | Disconnect the negative battery terminal, remove the hood, and clean the work area. |
| 2. Remove the old belt | Loosen the tensioner pulley, remove the old timing belt, and inspect the pulley for wear. |
| 3. Alignment marks | Make sure the timing marks on the crankshaft and camshaft are aligned to avoid misalignment. |
| 4. Install new belt | Install the new belt in the direction specified by the manufacturer, making sure that the tooth grooves match perfectly. |
| 5. Adjust the tensioning wheel | Use special tools to adjust the tension wheel to the specified tension to avoid being too tight or too loose. |
| 6. Inspection and testing | Manually turn the crankshaft two turns to confirm that the marks are aligned and there is no abnormal noise. |
2. Installation precautions
1.Timing mark alignment: Misalignment will cause the valve to collide with the piston, causing engine damage.
2.Belt tension: Too tight will accelerate wear, and too loose may cause tooth skipping.
3.Tool selection: Use special tools (such as a tension gauge) to ensure precise operation.
4.Regular replacement: It is recommended to replace it every 60,000-80,000 kilometers or 5 years (subject to the vehicle manual).
