1. Jack up the front wheels and support them by using a
rigid rack.
2. Manually turn the oil pump pulley a few times.
3. Turn the steering wheel all the way to the left and to
the right five or six times.
4. On vehicles with a petrol engine, disconnect the
high-tension cable. On vehicles with a diesel engine,
remove the fuel cut valve connector attached to the
injection pump.
Caution
Be careful not to position the high-tension cable near
the delivery pipe.
5. While operating the starting motor intermittently, turn the
steering wheel all the way to the left and right five or
six times (for 15 to 20 seconds).
Caution
(1) During air bleeding, refill the fluid so that the level
never falls below the lower position of the filter.
(2) If air bleeding is done while engine is running,
the air will be broken up and absorbed into the
fluid; be sure to do the bleeding only while
cranking.
6. On vehicles with a petrol engine, connect the high-tension
cable. On vehicles with a diesel engine, connect the fuel
cut valve connector attached to the injection pump. Start
the engine (idling).
7. Turn the steering wheel to the left and right until there
are no air bubbles in the oil reservoir.
8. Confirm that the fluid is not milky, and that the level is
up to the specified position on the level gauge.
9. Confirm that there is very little change in the fluid level
when the steering wheel is turned left and right.
10. Check whether or not the change in the fluid level is
within 5 mm when the engine is stopped and when it
is running.
11. If the change of the fluid level is 5 mm or more, the
air has not been completely bled from the system, and
thus must be bled completely.
Caution
(1) If the fluid level rises suddenly after the engine
is stopped, the air has not been completely bled.
(2) If air bleeding is not complete, there will be
abnormal noises from the pump and the
flow-control valve, and this condition could cause
a lessening of the life of the pump, etc.
