Honda CR-V: Evaporator Core
Replacement
1. Recover the refrigerant with a recovery/recycling/ charging station.
2. Remove the bolt from the A/C line clamp, and
remove the receiver line (A) from the clips (B).

3. Remove the nut, then disconnect the A/C lines (A)
from the evaporator core.

4. Remove the stud bolt.

5. Remove the blower unit.
6. Disconnect the connectors (A) from the evaporator
temperature sensor and the power transistor, then
remove the connector clip (B). Remove the
self-tapping screws, the expansion valve cover (C),
and the seal (D).

7. Carefully pull out the evaporator core (A) without
bending the lines, then remove the plate (B).

8. Remove the clips (A) and the evaporator
temperature sensor (B).
NOTE: At the factory, the evaporator temperature
sensor is installed at the 11th fin from the left side.

9. When the evaporator temperature sensor (A) is
reinstalled, set the evaporator temperature sensor
in the 12th fin from the left side.

10. Install the core in the reverse order of removal and
note these items:
- If you're installing a new evaporator core, add refrigerant oil (SP-10).
- 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 correct O-rings
for HFC-134a (R-134a) to avoid leakage.
- Immediately after using the oil, reinstall the cap
on the container, and seal it to avoid moisture
absorption.
- 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.
- Make sure that there is no air leakage.
- Charge the system.
