Checking Power Steering Oil Flow
IMPORTANT
• Use the instruction with the flowmeter when you use the
flowmeter.
• While testing, do not close the flowmeter loading valve
completely.
1. Disconnect the power steering controller hose (Inlet) (1) from
the power steering pipe (2).
2. Fix the inlet flow meter hose to the power steering pipe (2) and
the flow meter as shown in the photo.
3. Fix the flow meter return hose to the transmission fluid filling
port and the flow meter as shown in the photo.
4. Measure the flow volume of power steering.
The flow volume of pump is 8 L (2.1 U.S.gals, 1.8 Imp.gals) or
higher and verify the content below when the engine revolution
-1
is 1500 min (rpm).
5. If the flow volume varies from the specification, replace the
priority valve then take measurement again.
6. After measuring the flow volume, remove the flow meter then
reassembling the hydraulic pipe to the original position.
Condition
• Engine speed:
-1
1500 min (rpm)
