BLEEDING OF POWER STEERING


1.Raise the front wheels using a jack, and support with a rigid rack.
2.Disconnect the starter connector
(Refer to GROUP 16 - Starter System).
3.
caution
  • Keep the fluid level at MIN or higher than that during the bleeding operation.
  • Since the air is atomised into the power steering fluid if the bleeding is performed with the engine running, be sure to bleed the system while cranking the engine.
While cranking the engine intermittently with the starter motor several times (within 15 to 20 seconds), turn the steering wheel fully in both directions five or six times.
4.Connect the ignition coil connector, start the engine, and let it idle.
5.Turn the steering wheel fully in both directions until no bubbles can be seen in the oil reservoir.
6.Make sure that the fluid is no longer milky and that the fluid level is between MAX and MIN marks.
7.Make sure that the power steering fluid level in the reservoir does not change significantly when the steering wheel is turned to the left or right side.

8.
caution
  • If the fluid level goes up rapidly after the engine has been stopped, the power steering system is not bled sufficiently.
  • If the bleeding operation is not performed completely, the fluttering or abnormal noise may be produced from the pump and/or flow control valve, causing the durability performance of the pump to be reduced.
Check the fluid level variation between two engine conditions (engine starting and engine stopped).
9.When the fluid level variation is 5 mm or more, the power steering system is not bled sufficiently. In this case, bleed the system again.
