The causes of belt noise during cold start are: 1. The belt tightens due to low temperature before ignition, resulting in noise; 2. Severe belt aging with its service life nearing the limit; 3. The belt is either too loose or too tight. The functions of the belt are: 1. Ensuring accurate intake and exhaust timing; 2. Synchronizing engine ignition with cylinder movement; 3. Ensuring smooth power output from the engine. The method for replacing the vehicle belt is: 1. Lift the vehicle and remove the right front wheel fender liner; 2. Remove the generator belt and the generator belt tensioner; 3. Loosen the crankshaft pulley screw; 4. Open the engine hood and remove the water tank; 5. Remove the engine mounting bracket and the protective cover on the belt; 6. Unscrew the generator fixing screw and remove the generator; 7. Remove the cylinder block mounting bracket and take off the crankshaft pulley; 8. Rotate the crankshaft to the top dead center position of the cylinder and mark it; 9. Remove the belt and the tensioner.
