If the AC is still working then chances are it still has some refrigerant in the system . That needs to be recovered before you change the compressor , you cant just vent it to atmosphere .
You need recovery equipment , dry nitrogen, the correct oil and amount , a vacuum pump capable of pulling less than 250 microns , refrigerant gauge manifolds and the knowledge of how to use all the equipment .
thank you for your input.
my friend has equipment and I will ask him if he knows how do do all theses.
as far as oil goes it seems like it comes pre filled with oil and leak dye. See attached photo , there is epoxy like clear material on slot for philips flat head screw driver. To me it seems like during b manufacturing process they fill the oil, tighten the scre plug and put a drop of epoxy on it so it can’t be open easily
a new oem AC compressor for my 2001 dodge ram (if i ever needed one, which i don't) costs about 250. so i assume there is no good reason why it should cost more to make one for an aston martin. it's not as if it needs to possess some sort of aesthetic quality, or chicks ask you to lift the hood so they can check out your compressor (!). cold air will cool an aston cabin as well as the bog standard, bread truck white, bench-seated, standard transmissioned, 20 year-old one in my pick-up. so if i found one for about somewhere around 250 i wouldn't hesitate to buy it. anyway, 800/250? that's about the normal ratio.
Well finally got around to open and remove AC compressor
it was leaking at AC Controll valve
I removed the snap ring and was able to pull out AC control valve there are multiple o rings and those were probably the culprit.
I have new compressor as back up at hand but I love to fix things so I am going to find o rings then fill up with pag46 oil and install the old compressor , new receiver drier with all new o rings every where , vaccine the system and recharge it then see
Speaking from my 40yr commercial AC tech background . Chances are the compressor will come labelled as to if it needs oil or not and the type required .
However once you have installed the compressor how will you pressure test , properly evacuate and recharge the system with the correct amount of refrigerant .
This is not a DIY job and if done incorrectly that 800$ compressor will by a 2$ paperweight .
that's why when i punctured the refrigerant line in my sailboat's expensive 12v marinized freezer unit the least of my problems was finding and installing a new unit. it would be, i was convinced, someone to come out with the knowledge to re-install the refrigerant for the unit at a reasonable price so i punted... and converted my chart table into a space for a 120 dollar 110v refrigerator from walmart. after a couple of years now, there are times that an entire day goes by that i don't kick myself for punching a hole in that coolant line...
