1. Run the engine until the fluid temperature reaches 50°- 80°C (122°- 176°F) in the reservoir tank. Keep engine speed idle.
   CAUTION: Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and add fluid as needed.
2. Turn the steering wheel to the right and left several times.
3. Hold the steering wheel at each "locked" position for five seconds to check for fluid leakage.
   CAUTION: Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibility that the oil pump may be damaged.)
4. If fluid leakage at a connection is noticed, loosen the connection and then retighten. Do not over-tighten connector as this can damage O-ring, washer and connector. Refer to Power Steering Oil Pump: On-Vehicle Inspection and Service  and Hydraulic Line: Removal and Installation .
5. If fluid leakage from the oil pump is noticed, check the oil pump. Refer to Power Steering Oil Pump: On-Vehicle Inspection and Service .
6. Check steering gear boots for accumulation of fluid, indicating a leak from the steering gear.
