If you're installing a new evaporator core, add refrigerant
oil (PAG OIL).

•
|
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 or
R-1234yf to avoid leakage.

|
Immediately after using the oil, replace 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.
