(16) Align center take off on steering gear with the
tie rod assemblies. Install tie rod attaching bolts and
washers into steering gear assembly. Be sure wash-
ers are installed between tie rods and steering
gear (Fig. 28). Tighten the tie rod to steering gear
bolts to a torque of 100 N·m (74 ft. lbs.).
CAUTION: After tie rod attaching bolts are torqued,
bend the retaining plate tabs against heads of the
attaching bolts (Fig. 12).

(17) Install the vacuum hose for the power brake
booster on intake manifold vacuum port. Install hose
clamp on vacuum hose.
(18) Install the master cylinder on the power
brake vacuum booster. Install the two nuts attaching
the master cylinder to the booster. Tighten the mas-
ter cylinder mounting nuts to a torque of 28 N·m
(250 in. lbs.).
(19) Connect wire connector to the brake fluid
level switch on the side of the master cylinder fluid
reservoir.
(20) Install the in-line resonator and inlet hose
(Fig. 9) on the throttle body and air inlet hose com-
ing from the lid of the air cleaner housing.
(21) Install the cowl reinforcement on the vehicle
(Fig. 8). Install the eight bolts attaching the rein-
forcement to the strut towers. Install the bolt attach-
ing the wiper module to the reinforcement.
(22) Install the covers (Fig. 7) over the wiper mod-
ule and the cowl. Install and securely tighten the
attaching screws.
(23) Install the wiper arms (Fig. 6) on the pivots.
Install and securely tighten the wiper arm to pivot
attaching nuts. Install the caps on the wiper arms
covering the pivot nuts.
(24) Install the intermediate shaft onto the steer-
ing column shaft. Install steering column coupler
pinch bolt (Fig. 5) and tighten to a torque of 28 N·m
(21 ft. lbs.). Install the pinch bolt nut retaining pin in
pinch bolt.
(25) Remove the holding clamp from the steering
wheel (Fig. 4).
(26) Install the battery ground cable onto the
ground stud on the shock tower.
(27) Perform Power Steering Pump Initial Opera-
tion procedure to properly refill and bleed power
steering system. (Refer to 19 - STEERING/PUMP -
STANDARD PROCEDURE)
(28) Lower vehicle.
(29) Adjust front toe. (Refer to 2 - SUSPENSION/
WHEEL ALIGNMENT - STANDARD PROCEDURE)
SPEED PROPORTIONAL
STEERING SOLENOID

DESCRIPTION - SOLENOID CONTROL VALVE

The solenoid control valve is mounted on the speed
proportional power steering gear housing (Fig. 2).

OPERATION - SOLENOID CONTROL VALVE

Variable-effort power steering is provided by con-
trolling power steering fluid pressure at the power
steering gear. A solenoid control valve located on the
steering gear (Fig. 2) is used to control power steer-
ing gear return fluid pressure. The pressure is con-
trolled by varying the size of an orifice.
The variable-assist speed-proportional solenoid con-
trol valve is controlled by the Body Control Module
(BCM). The BCM receives the vehicle speed signal
sent from the Powertrain Control Module (PCM).
Upon receiving the vehicle speed signal from the
PCM, the BCM converts that speed signal into an
electrical current usable by the solenoid control valve
for controlling the variable effort of the power steer-
ing system.
The solenoid control valve is a serviceable compo-
nent of the variable-effort, speed-proportional power
steering gear assembly.

REMOVAL - SOLENOID CONTROL VALVE

(1) Disconnect the solenoid control valve electrical
connector from the wiring harness at the power
steering gear end cap below the brake master cylin-
der (Fig. 29).
(2) Unclip the connector from the gear end cap.
