Installation Notes
- Safety first: Switch off the engine, disconnect the battery where appropriate and allow all components to cool before starting work.
- Inspect the existing installation: Record the original belt routing and check the pulleys, tensioning components and surrounding parts for wear or damage.
- Remove the old belt: Release the applicable belt tensioning mechanism according to the engine service procedure and remove the belt without forcing it over the pulleys.
- Install the replacement: Route the new V-belt exactly as shown in the engine service information. Make sure the belt sits correctly in each pulley groove and is not twisted.
- Check tension and alignment: Set belt tension according to the engine manufacturer’s specification. Do not rely on a generic tension setting when a model-specific procedure is available.
- Final inspection: Rotate the system by hand where safe to confirm smooth movement and correct seating. Reconnect the battery and check belt tracking during a brief test run.
