10) Check the fluid leakage at flare nuts after turning
steering wheel from lock to lock with engine running.
CAUTION:
Before checking, wipe off any fluid on flare nuts and
piping.
In case the fluid leaks from flare nut, it is caused by
dust (or the like) and/or damage between flare and
tapered seat in piping.
So remove the flare nut, tighten again it to the speci-
fied torque after cleaning flare and tapered seat. If flare
or tapered seat is damaged, replace it with a new one.
11) Inspect fluid level on flat and level surface with engine
“OFF”by indicator of filler cap.
If the level is at lower point or below, add fluid to keep the
level in the specified range of the indicator. If at upper point
or above, drain fluid by using a syringe or the like.
