Flow Rate Test
- Connect Power Steering Analyzer (J-25323) into system. Fully open analyzer valve. Run engine until fluid reaches normal operating temperature. Check fluid level. Add fluid if necessary. Record pressure and flow rate.
- Close valve partially until pressure is 700 psi (49 kg/cm2 ), and then record flow rate. Subtract flow rate from that measured in step 1. If flow rate drops more than one gallon (3.8L) per minute, replace ring, rotor and vanes in pump. If flow rate does not drop one gallon (3.8L) per minute, go to next step.
- Increase engine speed to 1500 RPM, and record flow rate. Subtract flow rate from that measured in step 1. If difference between flow rates is more than one gallon (3.8L) per minute, remove and clean flow control valve. If not, go to next step.
- Turn steering wheel from stop to stop. Flow rate should be less than one gallon (3.8L) per minute at each stop. If flow rate is not as specified, check rack and pinion assembly for leakage.
- Turn engine off. Remove tester. Reconnect high pressure hose to pump. Check fluid level. Bleed hydraulic system. See HYDRAULIC SYSTEM BLEEDING under LUBRICATION.
