Fluid Pressure Inspection
1. Set the SSTs as shown in the figure.
KL ENGINE
49 G 0 3 2 351
49 G 0 3 2 3 53
49 G 0 3 2 352

3. Bleed the air from the system.
4. Open the gauge valve fully. Start the engine and
turn the steering wheel fully left and right to raise the
fluid temperature to
50— 60 °C (122— 140 ’ F}.
Tightening torque
40— 49 N m (4.0— 5.0 kgf-m, 29— 36 ft-lbf}
2. Disconnect the pressure pipe from the oil pump,
and connect the SSTs.
Caution
•
If the valve is left closed for more than 5
seconds, the fluid temperature will
increase excessively and adversely affect
the oil pump.
5. Close the gauge valve completely. Increase the
engine speed to 1,000— 1,500 rpm and measure
the fluid pressure generated by the oil pump. If the
pressure is not within the specification, repair or
replace the oil pump component.
Oil pump fluid pressure
FS engine: 7.9— 8.3 MPa
{80— 85 kgf/cm2, 1138— 1208 psi}
KL engine: 8.4— 8.8 MPa
{85—90 kgf/cm2, 1209— 1279 psi}

Caution
• If the steering wheel is kept in the fully
turned position for more than 5 seconds,
the fluid temperature will rise excessively
and adversely affect the oil pump.
