6A – 2IPOWER STEERING SYSTEM
DAEWOO V–121 BL4
DIAGNOSIS
POWER STEERING SYSTEM
PRESSURE TEST
Tools Required
KM–354–B Pressure Test Gauge Kit
Check the fluid pressure as follows to determine whether
the trouble is in the pump or the gear unit.
Test Procedure
1. Check the power steering fluid level and the power
steering pump belt tension. Refer to ”Checking and
Adding Fluid” in this section and Section 6B, Power
Steering Pump.
2. Disconnect the high pressure line at the pump. Use
a small container to catch any fluid.
3. Connect the hose of the pressure test gauge kit
KM–354–B to the power steering pressure hose
from the power steering pump.
4. Place the gear selector lever in PARK (automatic
transaxle–equipped vehicles) or NEUTRAL (manual
transaxle–equipped vehicles). Set the parking
brake.
5. Open the gauge valve fully.
6. Start the engine and let it idle.
7. Turn the steering wheel from lock to lock several
times to warm the fluid to operating temperature.
8. Increase the engine speed to 1,500 rpm.
Notice : The power steering pump could be damaged if
the valve is fully closed for more than 5 seconds.
9. Close the gauge valve fully, and read the pressure.
The pump pressure with the valve closed should be
between 8,330 kPa to 8,820 kPa (1,208 psi to
1,279 psi). With electronic variable orifice, the pres-
sure should be between 8,500 kPa to 8,960 kPa
(1,233 psi to 1,299 psi).
10. Immediately open the gauge valve fully.
11. Turn the steering wheel all the way to the left and
the right. If the pressure is within the specified lim-
its, the problem is not in the pump. Check the pow-
er steering gear for leaks.
POWER STEERING SYSTEM LEAK
TEST
General Procedure
Inspect the following:
S The fluid reservoir for overfill.
S Fluid for aeration and overflow.
S The hoses for loose connections.
S The torsion bar, stub shaft and adjuster seals for
leaks.
S The component sealing surfaces for damage.
Important : Verify the exact point of the leak. The point
from which the fluid is dripping is not necessarily the point
at which the system is leaking. When service is required,
clean the leak area upon disassembly, replace the leaking
seal, check the component sealing surfaces for damage
and reset the torque bolt to specifications, where required.
External Leak Check
The purpose of this procedure is to pinpoint the location of
the leak. In some cases, the leak can be easily located, but
seepage–type leaks may be harder to find. To locate seep-
age leaks, use the following method:
1. With the engine off, wipe dry the complete power
steering system.
2. Check the power steering fluid level in the pump’s
reservoir. Adjust the fluid level as necessary. Refer
to ”Checking and Adding Fluid” in this section.
Notice : Do not hold the steering wheel at a stop for any
length of time as this can damage the power steering
pump.
3. Start the engine. Turn the steering wheel counter-
clockwise and clockwise from stop to stop several
times.
4. Find the exact area of the leak and repair it.

6C – 12IPOWER STEERING GEAR

9. Remove the outer tie rod nuts and disconnect the
tie rod ends from the strut assembly using the ball
joint remover KM–507–B.
10. Remove the crossmember assembly. Refer to Sec-
tion 2C, Front Suspension.
11. On vehicles equipped with an automatic transaxle,
remove the transaxle center bracket. Refer to Sec-
tion 5A, Automatic Transaxle.
12. On vehicles equipped with a manual transaxle, re-
move the bolts securing the transaxle center brack-
et to the transaxle and the engine. Move the trans-
axle center bracket out of the way.
13. Remove the nuts and bolts from the steering gear
mounting bracket.
14. Remove the return line from the clip on the cross-
member.
15. Disconnect the rack and pinion assembly from the
crossmember assembly.
Installation Procedure
1. Install the rack and pinion assembly on the cross-
member. The steering gear must be in a straight–
ahead position, and the steering wheel spokes
must be vertical and pointing to the left. Align the
marks on the shafts to ensure proper positioning.
Seat the stub shaft into the intermediate shaft.

LITHING SYSTEMS 9B – 47
DAEWOO V–121 BL4
BACKUP LAMPS
The backup lamps are located in the rear combination
lamps They will come on when the transaxle is shifted into
reverse. On a vehicle with an automatic transaxle, the
backup lamps are activated by the neutral safety backup
(NSBU) switch. On a vehicle with a manual transaxle, they
are activated by a reverse switch which is part of the trans-
axle.
