Turning Effort

NOTE: Make sure that the front wheels are properly aligned and the tire pressure is correct before checking the effort.

1. Park the vehicle on dry concrete and set the parking brake.
2. Insert a thermometer into the power steering oil reservoir.
3. Idle the engine for two to three minutes. Turn the steering wheel from stop to stop several times to warm the fluid to 50-60° C (122-140° F).

CAUTION: Do not hold the steering wheel against the stops for more than three to five seconds at a time. Damage to the power steering pump will occur.

4. With the engine running, attach the Spring Scale to the rim of the steering wheel.
5. Measure the pull required to turn the steering wheel one complete revolution in each direction.
