Delphi a/c compressor warrenty
Some time ago it was mentioned that Delphi H-6 compressors appeared to be for R-134A only. Some time ago I sent a question in to Delphi on the subject. Here is that exchange:
My original question:
"The Delphi H-6 air conditioner compressor data sheet indicates that it is for R-134A refrigerant only.
Is there a reason R-12 is not listed for OEM replacements (e.g. it is pre-lubricated with incompatable lubricants) ? Is the warrenty voided if R-12 is used after a complete flush/lubrication replacement ?"
"We are unclear as to what you're inquiring about. This may be a compressor that was used in new vehicle production (indicated by a blue and white label on the compressor) or an older service compressor that was used for R-12 refrigerant systems.
However, if the label is orange and white, this is a service compressor that is compatible with R-12 and R-134a refrigerants.
The service compressors that do not have the orange and white label affixed to the compressor, were shipped with a mineral oil charge, for R-12 systems.
The compressors with the orange and white label are shipped without oil, and can be used on R-12 or R-134a. Lubricant will need to added to the compressor prior to its installation.
In any case, use of R-12 or R-134a will not void the product warranty, providing that proper air conditioning service procedures are used. (boldface mine).
