2. Before installing new oil filter, clan the oil filter mounting surface
on cylinder block and coat the rubber seal of the oil filter with
a little engine oil.
3. Install oil filter.
When installing oil filter, screw it in until a slight resistance is
felt, then tighten an additional 2/3 turn or more.

Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never attempt to change
the coolant when the engine is hot.
1. Set heater ªTEMPº control lever all the way to ªHOTº position.
2. Remove radiator cap and engine under cover.
3. Disconnect lower radiator hose to drain coolant.
Remove reservoir tank, drain coolant, then clean reservoir tank.
Re-install tank temporarily.
4. Remove cylinder block drain plug located at left rear of cylin-
der block.
5. Drain coolant and then tighten drain plug securely.
IApply sealant to the thread of drain
:30-40N×m (3.1 - 4.1 kg-m, 22.1 - 29.5 ft-lb)
6. Connect lower radiator hose.
7. Fill radiator and reservoir tank with water. Re-install radiator
cap and warm up engine.
8. Stop engine and wait until cools down.
9. Drain water.
10. Repeat step 2 through step 9 two or three times, until clear
water begins to drain from radiator.
11. Fill radiator with coolant up to the specified level.
Follow instructions attached to anti-freeze container for mixing
ratio of anti-freeze to water.
Coolant capacity (with reservoir tank):
10.0(8-3/4 Imp qt)
Slowly pour coolant through coolant filler neck to allow air in
system to escape.

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

NOTE:
If SRS does not enter Diagnosis mode even though malfunc-
tion is detected in User mode, check the battery voltage.

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.
