recommended oil ISUZU KB P190 2007 Workshop Repair Manual

0A-2 GENERAL INFORMATION
GENERAL REPAIR INSTRUCTIONS
1. Park the vehicle on level ground and chock the front or rear wheels before lifting the vehicle.
2. Raise the vehicle with a jack set against the axle or the frame.
3. Support the vehicle on chassis stands.
4. Use covers on the vehicle body, seats, and floor to prevent damage and/or contamination.
5. Disconnect the grounding cable from the battery before performing service operations.
This will prevent cable damage or burning due to short circuiting.
6. Handle brake fluid and antifreeze solution with great care.
Spilling these liquids on painted surfaces will damage the paint.
7. The use of the proper tool(s) and special tool(s) where specified is essential to efficient, reliable, and safe
service operations.
8. Always use genuine ISUZU replacement parts.
9. Discard used cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts at disassembly.
Normal function of these parts cannot be guaranteed if they are reused.
10. Prepare new cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts for installation.
11. Keep the disassembled parts neatly in groups. This will facilitate smooth and correct reassembly.
12. Keep fixing nuts and bolts separate. Fixing nuts and bolts vary in hardness and design according to installation position.
13. Clean all parts before inspection or reassembly.
14. Clean the oil ports and other openings with compressed air to make certain that they are free from dirt and obstructions.
15. Lubricate the rotating and sliding faces of all moving parts with oil or grease before installation.
16. Use the recommended liquid gasket to prevent leakage.
17. Carefully observe all nut and bolt torque specifications.
18. W hen removing or replacing parts that require refrigerant to the discharged from the air conditioning system, be sure to use the Vehicle Refrigerant Recovery and Recycling Equipment (VRRRE) to recover and recycle R134a,
to promote the aim of the protection of the ozone layer covering the earth.
19. Check and recheck your work. No service operation is complete until you have done this.

3B-8 POWER-ASSISTED STEERING SYSTEM
6. Fully close the shutoff valve. Record the highest
pressures.
・ If the pressure recorded is within 9800-10300 kPa
(100-105 kg/cm
2/1422-1493psi), the pump is
functioning within its specifications.
・ If the pressure recorded is higher than 10300 kPa
(105 kg/cm
2/1493psi), the valve in the pump is
defective.
・ If the pressure recorded is lower than 9800 kPa
(100 kg/cm
2/1422psi), the valve or the rotating
assembly in the pump is defective.
7. If the pump pressures are within specifications, leave the valve open and turn (or have someone
else turn) the steering wheel fully in both directions.
Record the highest pressures and compare with the
maximum pump pressure recorded in step 6. If this
pressure cannot be built up at either side of the
power steering unit, the power steering unit is
leaking internally and must be replaced.
8. Shut the engine off, remove the testing gauge.
9. Reconnect the pressure hose, check the fluid level and make the needed repairs.
10. If the problem still exists, the steering and front suspension must be thoroughly examined.

Maintenance
The hydraulic system should be kept clean, the fluid
level in the reservoir should be checked at regula
r
intervals and fluid added when required. Refer to
Recommended Fluids and Lubricants in General
Information section for the type of fluid to be used and
the intervals for filling.
If the system contains some dirt, flush it as described in
this section. If it is exceptionally dirty, the pump must be
completely disassembled before further usage. (The
steering unit cannot be disassembled.)
All tubes, hoses, and fittings should be inspected for
leakage at regular intervals. Fittings must be tight. Make
sure the clips, clamps and supporting tubes and hoses
are in place and properly secured.
Power steering hoses and lines must not be twisted,
kinked or tightly bent. Air in the system will cause
spongy action and noisy operation. W hen a hose is
disconnected or when fluid is lost, for any reason, the
system must be bled after refilling. Refer to Bleeding the
Power Steering System in this section.
・ Inspect gear for looseness or damage.
・ Inspect hoses to insure they are not touching an
y
other parts of the vehicle.
・ Inspect fluid level and fill to the proper level.

Fluid Level
1. Run the engine until the power steering fluid
reaches normal operating temperature, about 55 °
C (130 °F), then shut the engine off.
2. Check the level of fluid in the reservoir.
3. If the fluid level is low, add power steering fluid as
specified in General Information to the proper level
and install the receiver cap.
4. W hen checking the fluid level after the steering system has been serviced, air must be bled from
the system. Refer to Bleeding the Power Steering
System in this section.

Bleeding the Power Steering System
W hen a power steering pump or unit has been installed,
or an oil line has been disconnected, the air that has
entered the system must be bled out before the vehicle
is operated. If air is allowed to remain in the powe
r
steering fluid system, noisy and unsatisfactory operation
of the system may result.

Bleeding Procedure
W hen bleeding the system, and any time fluid is added
to the power steering system, be sure to use only powe
r
steering fluid as specified in General Information.
1. Fill the pump fluid reservoir to the proper level and let the fluid settle for at least two minutes.
2. Start the engine and let it run for a few seconds. Do not turn the steering wheel. 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. Raise and support the front end of the vehicle so that the wheels are off the ground.
6. Start the engine. Slowly turn the steering wheel right and left, lightly contacting the wheel stops.
7. Add power steering fluid if necessary.
8. Lower the vehicle, set the steering wheel at the straight forward position after turning it to its full
steer positions 2 or 3 times, and stop the engine.
9. Check the fluid level and refill as required.
10. If the fluid is extremely foamy, allow the vehicle to settle for a few minutes, then repeat the above
procedure.

Flushing the Power Steering System
1. Raise and support the front end of the vehicle off
the ground until the wheels are free to turn.
2. Remove the fluid return line at the pump inlet connector and plug the connector port on the pump.
Direct the line toward a large container to catch the
draining fluid.
3. W hile running the engine at idle, fill the reservoi
r
with new power steering fluid. Turn the steering
wheel in both directions. Do not contact or hold the
steering wheel to the wheel stops. This will cause
the pump to go to pressure relief mode, which ma
y
cause a sudden fluid overflow at the reservoir.

5. Crankshaft Thrust Bearing
Apply an ample coat of engine oil to the thrust bearings
before installation.
Install the thrust bearings to the crankshaft center journal.
The thrust bearing oil grooves must be facing the sliding
faces.
















6. Crankshaft Bearing Cap With Lower Bearing
Before the crankshaft bearing installation, select the
appropriate bearings in accordance with the description in
CRANK BEARING SELECTION of INSPECTION AND
REPAIR.
1. Apply the recommended liquid gasket or its equivalent to the No. 5 crankshaft bearing cap cylinder body fitting
surfaces at the points shown in the illustration.
NOTE:
Be sure that the bearing cap fitting surface is
completely free of oil before applying the liquid
gasket. Three bond 1207B Do not allow the liquid
gasket to obstruct the cylinder thread holes and
bearings.
ThreeBond 1207B is a fast-drying liquid gasket.
Tighten the bearing caps immediately after applying
the gasket.









2. Install the bearing caps with the bearing cap head
arrow mark facing the front of the engine.The bearing
cap numbers must be facing up.
3. Apply engine oil to the crankshaft bearing cap bolts.















4. Tighten the crankshaft bearing cap bolts to the
specified torque a little at time in the sequence shown
in the illustration.
