3. Check for abnormal noise from the tensioner pulley.
If you hear abnormal noise, replace the tensioner pulley.
4. Remove the drive belt.
5. Move the auto-tensioner within its limit with the belt tension release tool in the direction shown.
Check that the tensioner moves smoothly and without any abnormal noise. If the tensioner does not move smoothly or you hear abnormal noise, replace the auto-tensioner.
6. Remove the auto-tensioner.
7. Clamp the auto-tensioner (A) by using two 8 mm bolts (B) and a vise (C) as shown. Do not clamp the auto-tensioner itself.
8. Set the torque wrench (D) on the pulley bolt, and align it as shown.
9. Align the indicator (El on the tensioner base with center mark (F) on the tensioner arm by using the torque wrench, and measure the torque. If the torque value is out of specification, replace the auto-tensioner.
NOTE: If the indicator exceeds the center mark, recheck the torque.
Auto-tensioner Spring Torque: 32.5-39.7 N*m (3.31-4.05 kgf*m, 23.9-29.3 Ibf*ft)
