MAINTENANCE AND LUBRICATION 0B-9
1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug (1) to drain coolant.
3) Remove reservoir and drain.
4) Tighten plug securely. Also reinstall reservoir.
5) Fill radiator with specified amount of coolant, and run engine
for 2 or 3 minutes at idle. This drives out any air which may
still be trapped within cooling system. STOP ENGINE.
Add coolant as necessary until coolant level reaches the
filler throat of radiator. Reinstall radiator cap.
6) Add coolant to reservoir so that its level aligns with Full
mark. Then, reinstall cap aligning arrow marks on reservoir
and cap. CAUTION:
When changing engine coolant, use mixture of 50% water
and 50% ANTIFREEZE/ANTICORROSION COOLANT for
the market where ambient temperature falls lower than –
16°C (3°F) in winter, and mixture of 70% water and 30%
ANTIFREEZE/ANTICORROSION COOLANT for the market
where ambient temperature doesn’t fall lower than –16°C
(3°F).
Even in a market where no freezing temperature is antici-
pated, mixture of 70% water and 30% ANTIFREEZE/ANTI-
CORROSION COOLANT should be used for the purpose
of corrosion protection and lubrication.
1. Reservoir
2. Reservoir cap
3. FULL level marks
4. Arrow marks

1A-6 HEATER AND VENTILATION
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Drain engine coolant and disconnect heater hoses (1) from
heater unit.
3) Remove heater unit mounting nut (2).
4) Remove instrument panel by referring to “INSTRUMENT
PANEL” in Section 9.
5) Disconnect blower motor and resistor couplers from heater
unit.
6) Remove bolts (1), nuts (2) and screws (3) as shown.
7) Remove cooling unit (4) and heater unit (5) from vehicle.
INSTALLATION
Reverse removal procedure to install heater unit noting the follow-
ing instructions.
When installing each part, be careful not to catch any cable
or wiring harness.
Adjust heater control cable by referring to “HEATER CON-
TROL LEVER ASSEMBLY” in this section.
Fill engine coolant to radiator.

1A-12 HEATER AND VENTILATION
AIR INLET BOX
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Remove glove box.
3) Disable air bag system by referring to “DISABLING AIR BAG
SYSTEM” in Section 10B. (if equipped)
4) Disconnect fresh air control cable (1) from air inlet box.
1. Resistance board 4. Fresh air duct packing 7. Air inlet door 10. Cable clamp
2. Air inlet case
: Apply sealant 99000 - 31160 to hatched part “A”
5. Door link 8. Clip : Do not reuse
3. Fresh air duct case 6. Heater unit packing 9. Dash packing
NOTE:
If vehicle equipped with A/C, refer to “COOLING UNIT” in
Section 1B.
