Hi all - thanks in advance to the helpful input to follow.

I have a 2014 Town & Country with dual A/C. Recently, it underwent a catastrophic A/C hose breach (compressor high pressure/liquid line to condenser) which caused loss of refrigerant and PAG oil. In my case, the system was still fully functional from the factory; never needed to be serviced, so we assume it was properly charged. The hose breach was due to road debris when the A/C system was not running. I do not need to replace any other components; the compressor is still good.

Frequently, manufacturers have in their service manuals specific recommended estimates of partial oil quantities to add back into the system in the event of just such a loss. One reference I have found says the TOTAL SYSTEM CAPACITY is 5.07 of PAG-46, meaning this is the amount you put into a new system when fully charging it from new. Proper oil charge is critical. Too much oil and you risk sub-par performance and, at worst, potential hydraulic damage to the compressor. Too little oil and you risk starving the compressor leading to an agonizing compressor death.

My question is: what is the estimated amount of PAG-46 to put back into the system when recharging it? Please indicate your source for the information.

Some details to note: I have done A/C system repair, evacuation, and recharging many times. I have all of the tools needed (e.g., gauges, vacuum pump, etc.) to do the job properly. I will, of course, be using a new hose.

 

Anyone have any input?

Still hoping someone has some information on this query.....
