Note: To perform the replacement procedure, you will need a special tool: a device for reducing the tension of the drive belt (Snap-on YA9317 or other similar parts available on the market).
1. Turn the ignition switch to the "ON" (II) position and make sure the air conditioner switch is in the "OFF" position. Turn the ignition key to the "OFF" position.
2. Check the position of the auto-tensioner indicator needle. Start the engine, then check the auto-tensioner position again with the engine idling. If the indicator moves or fluctuates greatly, replace the auto-tensioner.
3. Check for increased noise levels in the tensioner pulley area. If unusual noises are present, replace the tensioner pulley.
4. Remove the drive belt.
5. Move the automatic tensioner within its range of movement using the drive belt tension release tool in the direction shown. Check that the tensioner moves smoothly without excessive noise. If the tensioner does not move smoothly or abnormal noise is heard, replace the automatic tensioner.
6. Remove the automatic tensioner.
7. Clamp the automatic tensioner A using two 8mm bolts B in a vice C as shown in the figure. Do not clamp the automatic tensioner body itself.
8. Place torque wrench D on the pulley mounting bolt in the direction shown.
9. Align the indicator E on the tensioner base with the center mark F on the tensioner arm using a torque wrench to determine the torque. If the torque is outside the range specified in the specification, replace the automatic tensioner.
Note: If the indicator goes beyond the center mark, check the torque again.
