Power Steering System
- Disconnect pressure hose from power steering pump and connect Pressure Gauge (MB990662-01) and Adapter (MB990993 or MB990994) between pressure hose and pump. Start engine and turn steering wheel until fluid temperature reaches 122°F (50°C). Set idle RPM.
- Slowly close pressure gauge shut-off valve to increase fluid pressure. Ensure RPM increases 200-250. Fluid pressure should be 213-284 psi (15-20 kg/cm2
). Slowly open valve and ensure engine speed returns to idle. Fluid pressure should be 100-284 psi (7-20 kg/cm2
). Remove pressure gauge and tighten fitting to 10-15 ft. lbs. (14-21 N.m). Bleed power steering system.
