Hydraulic System Pressure Test
- Disconnect pressure line at pump and connect pressure gauge and shut-off valve. Gauge must be between valve and pump. Open valve, check fluid level, and run engine for about 5 seconds.
- Check fluid level and restart engine. Turn steering wheel lock-to-lock several times to expel air from system and bring fluid temperature up. Check pressure quickly with wheel turned to full lock position (both left and right).HYDRAULIC SYSTEM PRESSURE
