RHA807H
1. Drain the cooling system. Refer to LC-17 (QG), LC-43 (YD),
“Changing Engine Coolant”.
2. Discharge the A/C system. Refer to HA-77.
3. Disconnect the two heater hoses from inside the engine com-
partment.
4. Remove the blower unit. Refer to HA-89.
5. Remove the steering member assembly. Refer to BT-25, “Instru-
ment Panel Assembly”.
6. Remove the heater unit.
7. Separate the heater & cooling unit case, and remove the
heater core.
INSTALLATIONNJHA0194Install in the reverse order of removal.
When filling radiator with coolant, refer to LC-18 (QG), LC-43
(YD), “Refilling Engine Coolant”.

A/C Evaporator
REMOVALNJHA02041. Use refrigerant collecting equipment (for HFC-134a) to dis-
charge refrigerant.
2. Disconnect the low-pressure flexible hose and the high-pres-
sure pipe from the evaporator.
CAUTION:
Cap or wrap the joint of the low-pressure flexible hose and the
high-pressure pipe with a suitable tool such as a vinyl tape to
avoid the entry of air.
3. Hold expansion valve and move it slightly upward. Push
