Installation Overview

1. Remove Old Pulley: Loosen the alternator shaft bolt using a Torx driver. Carefully detach the existing pulley, noting any alignment marks.
2. Prepare New Pulley: Clean the mounting surface and apply a thin layer of anti‑seize compound to the M16 threads.
3. Mounting: Align the 588001 pulley with the alternator shaft, ensuring the six channels match the shaft’s keyway. Tighten the bolt to the manufacturer’s torque specification (typically 70–80 Nm).
4. Check Alignment: Verify that the pulley rotates freely and that the alternator belt engages correctly without slippage.

Benefits of Choosing VALEO 588001

• Precision Fit: Exact dimensions prevent belt misalignment and reduce noise.
• Easy Replacement: Identical thread size (M16) and bolt pattern mean no additional hardware is required.
• Reliability: Proven performance in high‑RPM engines, ensuring consistent alternator output.

Maintenance Tips

• Inspect the pulley annually for cracks or surface wear; replace if any damage is observed.
• Keep the mounting area free of oil and debris to maintain a clean interface.
• Use a calibrated torque wrench when reinstalling to avoid over‑tightening, which can strip threads.
