Volkswagen Polo Service & Repair Manual: Refrigerant Circuit Pipes and Hoses
Caution
Non-approved tools or materials such as leak sealing
additives can cause damage or malfunctions in the
system. |
Only use tools and materials approved by the
manufacturer. |
The warranty is voided if non-approved tools or
materials are used. |
|
All components of the refrigerant circuit submitted for
quality observation are always to be sealed (use original
sealing caps of original part). |
Replace damaged or leaking components of refrigerant
circuit. Refer to
→ Chapter „Components, Replacing“. |
To date, the original parts (compressor, reservoir,
receiver/dryer, evaporator and condenser) have been filled with
nitrogen gas. This charge is being gradually discontinued. There
is little or no pressure equalization when removing the sealing
plugs from the original part. |
The mixture of refrigerant oil and refrigerant r134a
corrodes certain metals (e.g. copper) and alloys and dissolves
some hose materials. Therefore use original replacement parts
only. |
Pipes and hoses are joined by threaded connections or
special plug connectors. |
Note
Observe specified torque for threaded connections, use
appropriate release tools for plug connectors. |
