** NOTE: To evaluate this condition, it may be nec-
essary to disconnect the coupling at the base of the
steering column. Turn the steering wheel and feel or
listen for internal rubbing in steering column. To
avoid damaging the column clockspring, note the
following. Before disconnecting coupling, place
tires in the straight-ahead position and center steer-
ing wheel. Once disconnected, DO NOT rotate
steering wheel more than one revolution in either
direction and place steering wheel in original loca-
tion before reconnecting coupling. If this position is
lost, the steering column clockspring must be
recentered following the procedure found within the
procedure for steering column installation in the
steering column section.
POWER STEERING FLUID
CONDITION POSSIBLE CAUSES CORRECTION
LOW FLUID LEVEL WITH
VISIBLE LEAK.
1. Loose power steering hose
fittings.
1. Tighten the fitting to its specified torque.
2. Damaged or missing fitting seal,
gasket, or O-ring.
2. Replace as necessary.
3. Power steering fluid cooler
leaking.
3. Replace power steering fluid cooler.
4. Power steering pump or power
steering gear leaking.
4. Repair or replace the leaking component
as required.
AERATED FLUID. 1. Low fluid level.* 1. Fill power steering fluid reservoir to
proper level.
2. Air leak between power steering
fluid reservoir and pump.
2. Inspect for proper sealing. Replace the
power steering pump (with reservoir).
3. Cracked power steering pump
housing.
3. Replace the power steering pump.
RESERVOIR FLUID
OVERFLOW AND FLUID
THAT IS MILKY IN COLOR
1. Water contamination. 1. Drain the power steering fluid from the
system. Flush the system with fresh clean
power steering fluid, drain, then refill to the
proper level.
* NOTE: Extremely cold temperatures may cause
power steering fluid aeration if the power steering
fluid level is low.
DIAGNOSIS AND TESTING - SPEED
PROPORTIONAL POWER STEERING
Electronic diagnosis of the variable-effort speed-
proportional power steering system is done using the
DRBIIIt scan tool. Refer to Appropriate Diagnostic
Information to properly test and diagnosis this steer-
ing system.
