1. Check the power steering fluid level (see page 17-
21) and pump belt tension lsee page l7-20).
2.Start the engine, allow it to idle, and turn the steer-
ing wheel from lock-to-lock sev€ral times to warm
uo the fluid.
Attach a spring scale to the steering wheel. With the
engine idling and the car on a clean, dry floor, pull
the scale as shown and read it as soon 8s the tires
begin to turn,
il. The scal6 should read no more than 33 N (3.4 kgf,
7.5 lbf). lf it reads more or less, ch€ck the gearbox
and pump.

NOTE: Perform rack guide adjustment with the wheels
in the straight ahead position.
Loosen the rack guide screw locknut with the spe-
cialtool, then loosen the rack guide screw.
Tighten the rack guide screw until it compresses the
spring and seats against the .ack guide, then loosen
it.
Retighten the rack guide screw to 3.9 N.m {0.4
