NOTE :
Extremely cold temperatures may cause power steering fluid aeration. The air should work its way out of the system
as the fluid warms.
CONDITIONPOSSIBLE CAUSES CORRECTION
Low Fluid Level With Visible Leak · Loose power steering hose fittings
or connections.
· Damaged or missing O-ring at
power steering hose tube nuts.
· Power steering line or hose failure.
· Power steering component leaking
(reservoir, pump, gear).· Check torque on all tube nuts (at
gear and pump). Inspect clamps at
all rubber hose connections for
correct position, damage and
tension. Tighten tube nuts to
specifications as required.
Reposition or replace clamps at
hose connections. Clean joints and
reinspect for leaks.
· Remove tube nut and inspect
O-ring. If damaged or missing,
replace O-ring. Clean joints and
reinspect for leaks.
· Clean fluid from around suspect
areas. Run vehicle and inspect for
leaks. Look inside reservoir to see if
air is being ingested. Replace hoses
if necessary.
· Clean fluid from around suspect
areas. Run vehicle and inspect for
leaks. Look inside reservoir to see if
air is being ingested. Replace power
steering component if necessary.
Aerated Fluid · Low power steering fluid level.
· Air leak at power steering supply
hose, reservoir or pump.· Check fluid level and fill to proper
level if necessary. Check for leaks.
Make sure all air is bled from
system.
· Inspect components. Place a hand
vacuum pump with reservoir and
verify that system can sustain
vacuum. System should not lose
more than 1 psi in 2 minutes (make
sure vacuum pump is sealed well to
the reservoir). Replace steering
component if necessary.

Power Steering Filling and Flushing
Filling
1. Fill the power steering fluid reservoir to the proper level and let the fluid settle for at least two minutes.
2. Start the engine and let run for a few seconds, then turn the engine off.
3. Add fluid if necessary.
4. Repeat the above procedure until the fluid level remains constant after running the engine.
5. When the steering fluid temperature is relatively high, the steering fluid level will approach to the “MAX” level.
6. When the steering fluid cools down, the steering fluid level may approach to the “MIN” level.
NOTE :
If the steering fluid is extremely foamy or milky looking, allow the vehicle to stand a few minutes and repeat the
procedure.
Flushing
1. Raise and support the vehicle.
2. Remove the steering fluid reservoir release cap.
3. Siphon out the contaminated power steering fluid from the power steering liquid reservoir.
4. Remove the return hose clamp (1) from the power steering return hose.
5. Install a plug to the return hose fitting on the fluid reservoir.
6. Insert the power steering fluid return hose into a container for the discharged power steering fluid.
7. Fill the power steering fluid reservoir.
8. Start the engine and idle.
9. Let the engine idle until the return hose discharges clean power steering fluid.
10. Stop the engine and remove the plug from the power steering reservoir.
11. Reinstall the power steering return hose to the power steering reservoir.
12. Fill the power steering system (See Filling Procedure in Power Steering Filling and Flushing in Section 11 Steer- ing).
NOTE :
Approximately 1.0L of power steering fluid should be needed to fully flush the power steering reservoir. DO NOT mix
other fluids in the power steering fluid.

1. If the power steering fluid level is low, inspect the entire power steering system for potential leaks.
CAUTION:
DO NOT operate the vehicle with foamy steering fluid for an extended period. This may cause
pump damage.
2. Perform the following to inspect the power steering fluid reservoir level:•Park the vehicle on a level surface.
• Start the engine.
• Turn the steering wheel several times to heat the power steering fluid to 50°- 60°C.
• With the engine running, turn the steering wheel left and right to the wheel stops and repeat this several
times.
• Check the power steering fluid reservoir to see whether there is foam or milky fluid present. Check the
fluid level difference between engine off (2)
and engine running (1). If the fluid level varia-
tion exceeds 5 mm, air is in the system and
the air should be bled from the power steering
system.

There is some noise in all power steering systems. One of the most common is a hissing sound. Hiss is a high
frequency noise similar to that of a water tap being closed slowly. The noise is present in all valves that have a high
velocity steering fluid passing through an orifice. There is no relationship between this noise and steering perfor-
mance. The hissing sound is commonly heard during the following operations:
•Evident at a standstill
• At park with the engine running
• When the steering wheel is at the end of its travel

Description
The steering gear used is the rack-and-pinion type with power assist. It is mounted on the front suspension sub-
frame. The outer ends of the outer tie rods attach to the front knuckles.
NOTE :
The power steering gear should not be serviced or adjusted. If a malfunction or steering fluid leak occurs with the
steering gear, the complete steering gear needs to be replaced.
Operation
The steering wheel turns the pinion. The rack is a long flat bar with geared teeth on one side. The rack teeth mesh
with the teeth on the pinion gear. Rotation of the pinion moves the rack from left to right and right to left. The tie rod
then causes the wheels to turn to the left or right.

Description
The power steering pump is a constant flow rate and displacement vane type pump. The pump reservoir is detached
from the pump body. The pump is connected to the steering gear by the pressure and return lines.
Operation
The power steering pump is mounted to the engine and driven by the engine accessory drive belt. Power steering
fluid enters the pump from the reservoir. The power steering fluid is then trapped between the pump vanes and
moved to the high-pressure side of the pump creating a flow of steering fluid. The restriction of this flow by the
steering gear creates the pressure that provides the steering assist.
CAUTION:
•Operating the power steering with a low steering fluid level will damage the power steering sys-
tem.
• Holding the steering wheel in the full lock position for more than 3 seconds will damage the
power steering system.
