9. Install the core in the reverse order of removal, and note these items:
-
If you're installing a new evaporator core, add (POE) refrigerant oil (SANDEN SE-10Y). Using the wrong refrigerant oil can be a safety
hazard.
-
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, dispose of any remaining oil in the container, due to moisture absorption and short shelf life.
-
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.
