Power Steering

NOTE: 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 engine for five minutes.





WITH BELT TENSION GAUGE
1. Attach the belt tension gauge to the belt, and measure the tension of the belt. Tension:
^ Used Belt: 390 - 540 N (88 - 120 lbs.)
^ New Belt: 740 - 880 N (170 - 200 lbs.)

NOTE: Follow the manufacturer's instructions for the tension gauge.

2. Inspect the pump belt for cracks or any damage.
3. Replace the belt with a new one if necessary.





WITHOUT BELT TENSION GAUGE
Apply a force of 98 N (22 lbs.), and measure the deflection between the power steering pump and the crankshaft pulleys. Deflection:
^ Used Belt: 14.5 - 17.0 mm (0.571 - 0.669 inch)
^ New Belt: 10.5 - 12.5 mm (0.413 - 0.492 inch)
