Valeooscope - Air Conditioning System Thermal comfort loop

12. Why regular A/C servicing?

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
