Marvin,
Many thanks that’s such helpful clear info, just what I need !
I’ve been using the local ATS place to recharge a few cars for me – they have been ok and reasonably knowledgeable - when the V70 is reassembled they will pressurize it with nitrogen so I can check for leaks (using my gauge set) over a week or so before refilling with refrigerant. I asked the guy if the machine can add extra oil and he said yes – but when I explained I wanted 60cc extra to allow for new condenser/drier he said that was way more than he’s ever added (they only ever put in 10cc for a gas recharge). He was reluctant to put in more than 20cc total which left me once again concerned about how to get this bit as right as I can.
FWIW the system leaked down slowly so I think my oil loss will be minimal from this perspective.
Yes you are right some sources on the net show PAG 100 for P2 volvos – thanks to you I now know this is incorrect.
I didn’t ask ATS but I guess their machine would only have one type of oil to inject – I suspect they would use the most popular (whatever that is) and if you’re lucky you get the right viscosity and if not then tough ?!
I was pleased when my Nissens dryer turned up with plugged ports - I will expose it to the atmosphere for as short a time as poss when fitting.
Some internet info has said dryers arrive with the ports unplugged, and, if so, you need to boil off the absorbed moisture by evacuating the system for 30 mins – other sources say you cannot dry a dryer using this method – I don’t know which is correct on that one – just find it so frustrating at how much contradictory info there is out there !
