Installing The New Belt
Replacing your accessory belt is a key part of vehicle maintenance. Installing the new belt correctly ensures your vehicle runs smoothly. Follow these steps to install it properly.
Aligning The Belt

Place the belt on the pulleys. Make sure it fits into the grooves properly. Check all pulleys to ensure the belt is seated correctly.
Tension Adjustment
Next, adjust the tension of the belt. Proper tension prevents slipping and ensures the longevity of the belt.
Use a tension gauge to measure the belt tension. Refer to the vehicle’s manual for the correct tension specifications.
