1. |
Disconnect the negative (-) battery
terminal. |
2. |
Recover the refrigerant with a recovery/
recycling/ charging station. |
3. |
When the engine is cool, drain the engine
coolant from the radiator. |
4. |
Remove the expansion valve cover
(A).

|
5. |
Remove the bolts (A) and the expansion valve
(B) from the evaporator core.
Plug or cap the lines immediately after
disconnecting them to avoid moisture and dust
contamination.
Tightening
torque :
7.8 ~ 11.7 N.m ( 0.8 ~ 1.2 kgf.m, 5.7 ~
8.6 Ib-ft)
|

|
6. |
Disconnect the inlet (C) and outlet (D) heater
hoses from the heater unit.

Engine coolant will run out when the
hoses are disconnected; drain it into a clean drip pan. Be
sure not to let coolant spill on electrical parts or painted
surfaces. If any coolant spills, rinse it off
immediately. | |
7. |
Remove the crash pad (Refer to BD group-crash
pad). |
8. |
Disconnect the connectors from the temperature
control actuator, the mode control actuator and the evaporator
temperature sensor. |
9. |
Remove the cowl cross bar assembly. (Refer to
BD group-cowl cross bar) |
10. |
Remove the heater & blower unit after
loosening 3 mounting bolts.

|
11. |
Remove the blower unit (B) from heater unit
after loosening 3 screws.


|
12. |
Loosen the mounting screw and then remove the
heater core cover(A).

|
13. |
Loosen the heater unit lower case mount screw
and then remove the heater unit lower case (A).

|
14. |
Remove the evaporator core (A).

|
15. |
Be careful that the inlet and outlet pipe are

16. |
Installation is the reverse order of
removal. |
17. |
Installation is the reverse order of removal,
and note these items :
A. |
If you're installing a new evaporator,
add refrigerant oil
(ND-OIL8). |
B. |
Replace the O-rings with new ones at
each fitting, and apply a thin coat of refrigerant oil before
installing them. Be sure to use the right O-rings for R-134a
to avoid leakage. |
C. |
Immediately after using the oil, replace
the cap on the container, and seal it to avoid moisture
absorption. |
D. |
Do not spill the refrigerant oil on the
vehicle ; it may damage the paint ; if the refrigerant oil
contacts the paint, wash it off
immediately |
E. |
Apply sealant to the
grommets. |
F. |
Make sure that there is no air
leakage. |
G. |
Charge the system and test its
performance. |
H. |
Do not interchange the inlet and outlet
heater hoses and install the hose clamps
securely. |
I. |
Refill the cooling system with engine
coolant | | |
