Installation & Maintenance Recommendations
IMPORTANT: Professional Installation Recommended
Pre-Installation Checklist:
  • The tensioner must be installed at room temperature -- allow the engine and tensioner to stabilise to the same ambient temperature for proper belt tension adjustment
  • Inspect the serpentine belt for cracks, glazing, or wear. Replace belt simultaneously for optimal performance
  • Check all other idler pulleys and accessories for smooth operation
Installation Guidelines (Reference workshop manual):
  1. Disconnect the negative battery terminal
  2. Rotate the tensioner arm using a breaker bar or serpentine belt tool to relieve belt tension
  3. Remove the old serpentine belt from the pulleys
  4. Remove the tensioner mounting bolt (M10x60 12-point socket bolt)
  5. Remove the old tensioner assembly
  6. Clean the mounting surface thoroughly
  7. Install the new tensioner and torque mounting bolt to manufacturer's specified torque settings (refer to vehicle-specific workshop manual)
  8. Route the new serpentine belt according to the belt routing diagram
  9. Rotate the tensioner arm and slip the belt over the final pulley
  10. Start the engine and let it idle for 2-3 minutes to verify smooth operation and check for unusual noises
Maintenance Schedule:
  • Inspection: Every 50,000 km / 12 months. Listen for squealing, check belt condition, and inspect for visible damage
  • Replacement: Recommended at 160,000 km or earlier if symptoms appear
  • Note: Recommended to be replaced any time accessory belt work is performed
