Deflection Method: Inspection

Apply a force of 98 N (10 kgf, 22 lbf) and measure the deflection between the power steering pump pulley (A) and the crankshaft pulley (B).
Deflection:
1. Used Belt 13.0 - 16.5 mm (0.51 - 0.65 in )
2. New Belt - 8.5 - 11.0 mm (0.33 - 0.43 in )
If you installed a new belt, run the engine for 5 minutes, then readjust the belt to the used belt specifications.
