(5) Position locating pin on power steering pres-
sure hose banjo fitting so it is against power steering
pump mounting bracket (Fig. 4). While holding locat-
ing pin against power steering pump bracket, torque
banjo bolt to 34 N·m (25 ft. lbs.).
POWER STEERING PUMP SUCTION PORT SEAL
The power steering pump does not require removal
from the engine for removal and replacement of the
suction port O-Ring seal.
REMOVE
(1) Remove power steering fluid supply hose from
power steering pump suction port fitting (Fig. 6).
(2) Remove bolt (Fig. 6) attaching power steering
pump suction port fitting to the power steering
pump.
(3) Remove the suction port fitting (Fig. 6) from

REMOVAL AND INSTALLATION
POWER STEERING PRESSURE SWITCH
On vehicles equipped with power steering, a power
steering pressure switch is used to improve the vehi-
cle's idle quality. The pressure switch improves vehi-
cle idle quality, by controlling engine idle speed when
required.
The pressure switch functions by signaling the
power train control module, that the power steering
system is putting additional load on the engine. This
type of condition exists when turning the front tires
of the vehicle, when the vehicle is stationary and the
engine is at idle speed. When this condition is sensed
by the power train control module, through a signal
from the power steering pressure switch, engine idle
speed is increased. This increase in engine idle speed
compensates for the additional load, thus maintain-
ing the require engine idle speed and idle quality.
The power steering pressure switch (Fig. 7) is
mounted directly to the power steering gear on vehi-
cle's requiring its usage.
