A/C system hoses and lines
The mixture of refrigerant oil (PAG oil) and
refrigerant R-134a attacks some metals and
alloys (for example, copper) and breaks down
certain hose material. Use only factory specified
replacement hoses and lines.
Hoses and lines are fastened together with
threaded couplings/fittings and are retained (to
bodywork or components) with specially isolated
hose clamps.
Notes:
During servicing, all couplings, fittings and
related fasteners must be torqued to
specifications Page 87-89
Ensure that only special tools (as specified) are
used while servicing.
