5. Remove the bolts, then remove the A/C condenser by lifting it up. Be careful not to damage the radiator or the A/C condenser fins when removing the A/C condenser.
6. Install the A/C condenser in the reverse order of removal, and note these items:
- If you're installing a new A/C condenser, add refrigerant oil (DENSO ND-OIL 8).
- 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.
