1. Make certain that the clearance between the actuator idle con-
trol lever pin and the injection pump control lever is within the
specified limits.
2. Adjust idle speed to specified rpm without the air conditioner
operating.
3. Then check the idle speed when the air conditioner is operat-
ing and make sure it is correct.
Unit: rpm
Idle speed (Air conditioner: ªONº) 850 50

2. Set theGmark of the filter body to the top position and dis-
charge the oil.
IReceive the oil discharged from the drain hose in a tray.
IAbout 500 cc (17.6 Imp fl oz) of oil will be discharged in about
3 minutes.
IThe oil is discharged from the oil catcher to under the vehicle
through the drain hose.
3. Remove the filter body, and then remove the oil filter element.
CAUTION:
IIf the engine oil gets on the engine or vehicle, thoroughly
wipe it off.
IThoroughly wipe off the oil remaining in the oil catcher.
(This is to prevent misidentifying oil leaking from the oil
catcher as oil leaking from the engine.)
4. Remove the O-ring from the filter body.
IPress the O-ring in any direction with your finger, and pull on
the portion of the O-ring separated from the filter body to
remove it.
CAUTION:
Because wire and screwdrivers may cause damage to the fil-
ter body, do not use such tools.
INSTALLATION
1. Thoroughly remove foreign matter adhering to the inside of fil-
ter body and O-ring mounting areas (of the body and oil cooler).
2. Install the oil filter element and O-ring to the filter body.
ISecurely press the oil filter element into the filter body.
3. Install the filter body.

4. After warming up the engine, check that no engine oil leaks.
Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
ÐDRAINING ENGINE COOLANTÐ
1. Move heater TEMP control knob all the way to HOT.
2. Remove undercover and disconnect lower radiator hose to
drain coolant.
3. Remove radiator filler cap.

4. Remove cylinder block drain plug located at left center of cyl-
inder block.
5. Remove reservoir tank and drain coolant.
ÐREFILLING ENGINE COOLANTÐ
6. Install reservoir tank, radiator drain plug, and cylinder block
drain plugs.
IApply sealant to the thread of cylinder block drain plug.
Cylinder block drain plug:
:24-26N×m (2.4 - 2.7 kg-m, 18 - 19 ft-lb)
7. Move heater TEMP control knob all the way to HOT.
8. Fill radiator with coolant up to the filler neck.
For coolant mixture ratio, refer to MA-19.
9. Fill reservoir tank with coolant up to the MAX level.
Coolant capacity (With reservoir tank):
10.6(9-3/8 Imp qt)
Reservoir tank capacity (for MAX level):
0.75(5/8 Imp qt)
Pour coolant through coolant filler neck slowly to allow air in
system to escape.
10. Install radiator cap.
11. Warm up engine to normal operating temperature.
12. Run engine at 2,000 rpm for 10 seconds and return to idle
speed.
IRepeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
13. Stop engine and cool it down.
ICool down using a fan to reduce the time.
14. Remove the radiator cap and check coolant level.
IIf necessary, refill radiator up to filler neck with coolant.
15. Refill reservoir tank to Max line with coolant.
16. Repeat step 9 through step 15 two or more times.
17. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 2,000 rpm with heater tempera-
ture control set at several positions between COOL and HOT.
ISound may be noticeable at heater water core.
18. If sound is heard, bleed air from cooling system by repeating
steps 11 through 17 until coolant level no longer drops.
IClean excess coolant from engine.
Checking Cooling System
CHECKING HOSES AND CLAMPS
Check hoses and clamps for proper attachment, leaks, cracks,
damage, loose connections, chafing and deterioration.

System Description
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to alternator terminal 4 (S) through:
I10A fuse (No. 31, located in the fuse and fusible link box).
Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage
is controlled by the IC regulator at terminal 4 (S) detecting the input voltage (ZD30DDTi engine models). The
charging circuit is protected by the 100A (A/T models) fusible link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
Ithrough 10A fuse [No. 12, located in the fuse block (J/B)]
Ito combination meter terminal 28 for the charge warning lamp.
Ground is supplied to terminal 2 of the combination meter through terminal 1(L) (TD27Ti engine models) or
3(L) (ZD30DDTi engine model) of the alternator. With power and ground supplied, the charge warning lamp
will illuminate. When the alternator is providing sufficient voltage with the engine running, the ground is opened
and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.
CHARGING SYSTEM
SC-23

Checking Hydraulic System
Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve, then bleed air. (Refer to ªBleed-
ing Hydraulic Systemº, ST-5.)
2. Run engine.
Make sure temperature of fluid in tank rises to 60 to 80ÉC (140
to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, oil pressure in oil pump will
increase to relief pressure, resulting in an abnormal rise in oil
temperature.
3. Check pressure with steering wheel fully turned to left and right
positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
Oil pump maximum standard pressure:
TD27Ti engine
8,800 - 9,200 kPa (88 - 92 bar,
89 - 93 kg/cm
2, 1,276 - 1,334 psi)
ZD30DTi engine
9,800 - 10,500 kPa (98.0 - 105.0 bar,
99.96 - 107.10 kg/cm
2, 1,421 - 1,523 psi)
4. If oil pressure is below the maximum pressure, slowly close
shut-off valve and check pressure.
IWhen pressure reaches maximum pressure, gear is damaged.
IWhen pressure remains below maximum pressure, pump is
damaged.
CAUTION:
Do not close shut-off valve for more than 15 seconds.
5. If oil pressure is higher than maximum pressure, check oil
pump flow control valve.
6. After checking hydraulic system, remove Tool and add fluid if
necessary, then completely bleed air out of system.NST033
