2. Disconnect the injection hose.
Note: Make a match mark before disconnecting the hose.
3. Connect the pressure gauge as shown.
- Tightening torque - 29-44 Nm
4. Bleed the system to remove air (see section "Bleeding the power steering system").
5. Fully open the pressure gauge valve.
6. Start the engine, to warm up the liquid to 50-60°C, turn the steering wheel to the right and left several times until it stops.
Attention: if you hold the steering wheel in the extreme position for more than 5 seconds, this will lead to a sharp increase in fluid temperature and damage to the pump.
7. Completely close the pressure gauge valve.
Caution: Leaving the pressure gauge valve in the closed position for more than 5 seconds will result in a sharp rise in fluid temperature and damage to the pump.
8. Bring the engine speed to 1000-1500 rpm, measure the fluid pressure developed by the hydraulic booster pump.
- The minimum allowable pressure is 9.3-9.8 MPa
If the measured pressure is lower than the set pressure, repair or replace the power steering pump.
9. Measure fluid pressure with gauge valve open.
A) Open the valve fully again and bring the engine speed to 1000-1500 rpm.
b) Turn the steering wheel all the way to the right and all the way to the left and measure the developed pressure.
Attention: if you hold the steering wheel in the extreme position for more than 5 seconds, this will lead to a sharp increase in fluid temperature and damage to the pump.
- The minimum allowable pressure is 9.30-9.79 MPa
If the measured pressure is lower than the specified pressure, replace the steering gear assembly.
10. Remove the pressure gauge, connect the pressure hose.
- Tightening torque - 31-47 Nm
11. Bleed the system to remove air (see section "Bleeding the power steering system").
