Installation Guide

1. Ensure the engine is off, cool to the touch, and the battery is disconnected for safety.
2. Locate the power steering pump and identify the old V-belt that requires replacement.
3. Loosen the tensioner pulley or the pump's pivot bolts to release tension from the belt.
4. Carefully slide the old belt off all pulleys, noting its path.
5. Compare the old belt with your new one to confirm it is the correct size.
6. Route the new V-belt around the pulleys, following the diagram for your specific engine.
