Removal

  1. Remove the drive belt.
    1. Using a wrench, turn the drive belt tensioner (A) counterclockwise.
    2. Disconnect the drive belt (A).
    3. Remove the drive belt tensioner (A), then remove the drive belt (B).

Inspection

  1. Inspect the belt for maintenance and abnormal wear of the ribs. Replace if necessary.
    • Do not bend, twist, or turn the drive belt inside out.
    • Do not allow the drive belt to contact oil, water, or steam.
  2. Visually inspect the belt for excessive wear, frayed cords, etc. If any defect is found, replace the drive belt.
    • Cracks on the belt ribs are acceptable. If any rib sections are missing from the belt, replace it.
Drive Belt Tension Measurement and Adjustment

Belt Tension Measurement

Measure the belt tension using a mechanical tension gauge or a sonic tension meter. Belt tension - New belt: 637.4 ~ 735.5 N (65 ~ 75 kgf, 143.3 ~ 165.3 lbf). Used belt: 441.3 ~ 539.4 N (45 ~ 55 kgf, 99.2 ~ 121.3 lbf)
  • If the engine has been running for 5 minutes or more, adjust the belt tension as for a used belt.
  • When installing the poly-V belt, make sure all pulley grooves are covered by the belt ribs.
  • A loose belt causes slipping noise.
  • An excessively tight belt may damage the alternator and water pump bearings.

Using a mechanical tension gauge (type BT-33-73F, BTG-2)

  1. While pressing the handle (A) of the gauge, insert the belt (B) between the pulley and the pulley (or idler pulley) into the gap between the spindle (C) and the hook (D).
  2. Release the handle (A), then read the value on the scale indicated by the pointer (B).

Using a sonic tension meter (type U-505/507)

  1. Enter the belt specifications into the tension meter (A).
    Belt Type Measurement Point Input Data
    M (Mass, g/m) W (Width, ribs) S (Span, mm)
    With A/C Crankshaft pulley to A/C compressor pulley 14.1 006.0 187
    Without A/C Crankshaft pulley to alternator pulley 14.1 006.0 Actual measured value

    • Measurement S (range): Calculate the average value after measuring the distance 3-4 times.
  2. Position the microphone (B) closer to the center of the belt (A) and tap the belt with your finger 2-3 times. Read the value on the display. [With A/C]
    [Without A/C]

Installation

  1. Install the drive belt.
    1. Install the drive belt (B), then install the drive belt tensioner (A). Torque: Center bolt: 29.4 - 41 N·m Mounting bolt: 39.2 - 49 N·m
    2. Using a wrench, turn the drive belt tensioner (A) counterclockwise.
    3. Connect the drive belt (A).
    4. Remove the wrench.
