Alternator Belt Inspection and Adjustment
ALTERNATOR BELT INSPECTION AND ADJUSTMENTNOTE: When using a new belt, first adjust the deflection or tension to the values for the new belt, then readjust the deflection or tension to the values for the used belt after running engine for five minutes
Deflection method:
Apply a force of 98 N (10 kgf, 22 lbf), and measure the deflection between the alternator and crankshaft pulley.
Deflection
Used Belt: 8.5 11.5 mm (0.33 0.345 in)
New Belt: 5.5 8.0 mm (0.22 0.361 in)
NOTE: If the belt is worn or damaged, replace it.
Belt tension gauge method:
Attach the belt tension gauge to the belt and measure the tension. Follow the gauge manufacturer's instructions.
Tension:
Used Belt: 340-490 N (35-50 kgf, 77-110 lbf)
New Belt: 690-880 N (70-90 kgf, 150-200 lbf)
NOTE: If the belt is worn or damaged, replace it.
If adjustment is necessary:
1. Loosen the adjusting bolt(A) and the lock bolt(B).
2. Move the alternator to obtain the proper belt tension, then retighten the nuts.
3. Recheck the deflection or tension of the belt.
NOTE: For the power steering pump belt and A/C compressor belt adjustments.
