12.4 Expert practices
The maintenance and repair of the A/C loop must
be considered as an operation on the whole system.
The failure of one component can have a serious
impact on the rest of the loop so it is important to
combine certain operations in order to guarantee
the performance and reliability of the replaced
parts.
Take the compressor, for example. In order to
extend the Valeo warranty to the new part, the
operator must perform the following operations:
g
Flush the loop to eliminate any metal residue
from the components
g
Replace the receiver drier
