Refrigerant Circuit Pipes And Hoses
WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.
The mixture of refrigerant oil and refrigerant R134a corrodes certain metals (such as copper) and alloys and dissolves some hose materials. Therefore use original replacement parts only.
Pipes and hoses are joined by threaded connections or by special connectors.
NOTE:
Note the tightening specification for threaded connections and use the appropriate release tools for connectors.
