A/C System Repair Information
| An A/C system made for refrigerant R12 must not be filled
with refrigerant R134a without making modifications to the
refrigerant circuit. Refer to
→ Chapter „Refrigerant Circuit, Converting R12 to R134a and
Servicing“. |
| The refrigerant oils specifically developed for R134a and
R12 refrigerant circuits are never to be mixed. |
| Service stations which come in contact with the refrigerant
are only to be used for the intended refrigerant. |
| Components of R134a refrigerant circuits can be identified
by their markings, green labels or design (such as different
threads) to prevent interchanging with components designed for
refrigerant R12. |
| A label indicating the refrigerant used is provided in the
engine compartment on the lock carrier or in the plenum chamber. |
| Different refrigerants are never to be mixed. |
 Note
| When working on the refrigerant circuit, always heed the
information given in the sections on “Safety measures”. Refer to
