PREPARATION
- Ensure belt tension is correct. Disconnect power steering pump pressure hose. Keep hose end raised to prevent fluid loss. Connect Pressure Gauge (J-5176-D) hose to power steering pump fitting. Connect other hose from valve side of tester to steering gear inlet.
- Open valve. Run engine until fluid reaches normal operating temperature of 150-170°F (66-77°C). Check fluid level. Add fluid (if necessary).
PRESSURE TEST
- Note pressure reading with valve open and engine idling. Pressure should be 80-125 psi (6-9 kg/cm 2 ). If pressure is above 200 psi (14 kg/cm 2 ), check hoses for restrictions and poppet valve for proper assembly.
- Completely close and reopen gate valve 3 times. Record highest reading each time. DO NOT close valve longer than 5 seconds. Readings should be within specifications. On "G", "P" and "R" & "V" Series (Scheme 1) On all other models, see PRESSURE TEST SPECIFICATIONS TABLE.
- If readings are within specifications and within 50 psi (4 kg/cm 2 ) of each other, pump is operating properly. On "G", "P" and "R" & "V" Series (Scheme 1) On all other models, see PRESSURE TEST SPECIFICATIONS table.
- If readings are higher than specifications and not within 50 psi (4 kg/cm 2 ) of each other, flow control valve in pump is sticking. Remove and clean or replace flow control valve.
- If pressure is constant but more than 100 psi (7 kg/cm 2 ) below specifications, clean or replace flow control valve in pump. If readings are still low, replace pump.
- If pump is within specifications, open valve, and turn steering wheel from right to left stops. Record pressure. DO NOT hold wheel against either stop longer than 5 seconds.
- Pressure should be within specifications. On "G", "P" and "R" & "V" Series (Scheme 1) On all other models, see PRESSURE TEST SPECIFICATIONS TABLE. If pressure is low, steering gear is leaking internally and must be repaired.

SERVICE INTERVALS
Check fluid at every oil change.
CHECKING FLUID LEVEL
Check fluid with engine stopped and fluid hot or cold. Fluid level must be at FULL-HOT or FULL-COLD mark on dipstick. On models with remote reservoir, fluid level must be .5-1.0" from top of reservoir with wheels turned fully left.

RECOMMENDED FLUID
REFILLING & BLEEDING SYSTEM
- Fill reservoir to correct level. Let oil settle 2 minutes. Start engine, and run it 4-5 seconds. Check reservoir. Add fluid (if necessary). Repeat procedure until level in reservoir remains constant.
- Raise vehicle so both front wheels leave ground. Start engine, and increase engine speed to 1500 RPM. Turn wheels right and left, lightly contacting stops. Check fluid level. Add fluid (if necessary).
- Lower vehicle. Turn wheels right and left. Check fluid level. Add fluid (if necessary). If fluid is foamy, proceed to step 4).
- Turn off engine. After letting vehicle sit for a few minutes, repeat steps 1) through 3). Check fluid for air in system. If fluid level is low and air is apparent, repeat complete procedure.
