6. Install the core in the reverse order of removal, and
note these items.
• II you're installing a new evaporator core, add
refrigerant oil (KEIHIN SP-10) (see page 21-6).
• Replace the G-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.
• Charge the system (see page 21-551.
