For precise fitment, consult the vehicle’s service manual or Dayco’s part number cross‑reference guide. The APV2424 is available in multiple variants to accommodate different belt widths and engine layouts.

Installation Procedure

1. Preparation: Disconnect the battery, remove any protective covers, and ensure the engine is cool before starting work.
2. Belt Removal: Loosen the existing tensioner or use a belt‑pulling tool to release tension on the timing belt. Carefully unwind the belt from the pulleys.
3. Remove Old Tensioner: Detach the mounting bolts securing the old tensioner. Note any alignment marks or orientation indicators that may be present.
4. Install APV2424: Position the new tensioner in place, aligning it with the engine’s pulley system. Secure it using the supplied bolts and torque to manufacturer specifications.
5. Belt Re‑installation: Route the belt around all pulleys, ensuring proper alignment on each tooth. Use a belt tension gauge or the built‑in tensioner adjustment feature to achieve correct tension.
6. Final Checks: Verify that the belt runs smoothly without rubbing against any components. Reconnect the battery and perform a short engine run to confirm proper operation.

Maintenance Tips

• Inspect the tensioner regularly for signs of wear, such as bearing noise or uneven belt contact.
• Clean the pulley housing with a mild solvent to remove oil and debris that could affect performance.
• Replace the tensioner if any component shows excessive play or if the belt begins to slip during operation.
