NHTSA site says 0 unrepaired recalls for the VIN. Not sure how to find closed recalls. I recall a couple but not what they were.

Re: Replacing AC condenser on a 2016 Leaf S

Curious on the AC Oil. Label on inside of hood states "oil: AE10 - refrigerant: HFC134a 0.45kg"

https://www.mynissanleaf.com/viewtopic.php?t=25931 states "I believe my 2014 Leaf uses ND-11 type compressor oil. Nissan calls it AE10"

https://supercool.ac -> "Resources" -> "Lubricant Specification Guide" "2016 Leaf S" -> "ND-11 (POE)"

[I believe this following may be bad info?] https://www.mynissanleaf.com/viewtopic. ... 16#p587816 states "S uses AE10 oil while SV and SL (with heat pump system) use ND11 oil."

https://supercool.ac -> "Resources" -> "Lubricant Specification Guide" "2016 Leaf SV and SL" -> "Type R (PAG) 100"

https://pdf4pro.com/cdn/ac-lubricants-i ... -1dcca.pdf also seems to claim that AE-10 and ND-11 both equate to "POE 80" and "Airstal 113-0087" "Di-electric strength 75kV per 2.5mm"

That is what it says in my 2015 owners manual, but the service manual shows ND11 for both heat-pump AND non-heat-pump systems. My 2012 owners manual specifies "ND-OIL11" also. There was no heat-pump that year.

I noticed you're still working with polymers.

Re: Replacing AC condenser on a 2016 Leaf S

The factory service manuals for both 2015 and 2016 show ND-OIL11 for both systems (with and without heat pump). According to those service manuals, oil volume is 140 ml for heat pump system and 150 ml without heat pump. Also, the service manual for 2011 shows 150 ml of ND-OIL11 for the air conditioning system. The label under the hood of my 2019 SL Plus with heat pump also shows ND-OIL11.

Anyways my bad I should have read the service manual. Thanks

Re: Replacing AC condenser on a 2016 Leaf S

Well shoot.

I'd not looked closely before. Only noticed it when I was poking around assessing how hard the condenser removal would be.

Pretty confident I didn't do it.

Either:
a) failed after I got it back from the dealer (coincidence)
b) the dealer damaged it [after their diagnosis]
c) that it's the actual cause of the leak [their diagnosis that there was a crack in the input line of the condenser - they quoted me a new condenser, not a new high pressure pipe - was badly wrong] I guess it's worth running a vacuum test with the old condenser still installed after I replace the high pressure pipe to confirm this before I go replacing the condenser (I bought a replacement condeser already).

What is also odd is that the high pressure cap is missing off the high pressure pipe, they're the only dealer to every work on the a/c and the dye/R134a should have been applied into the low pressure side (I can see remains of dye on the low pressure connector).

Pipe was easy to get off, new one is $83 from the local Nissan dealer (15% discount): Nissan part# 92440-3NK0A

I'm a bit surprised that there isn't a second stabilizing arm for the high pressure pipe closer to the condenser I wonder if this cracking is a common issue?

I'm also thinking now I'll do the whole job myself. Plenty of people have done so on the Prius forum. I can get ND11 at my local auto parts house.

My only question is how much oil to add. The top of page 89 of HA.pdf has the following table:

Replace evaporator 35ml
Replace condenser 15ml
Replace liquid tank 5ml
Refrigerant leakage is detected
- Large amount leakage 30 ml
- Small amount leakage — ml
Lubricant amount that is recycled together with refrigerant during recycle operation [alpha] ml

I'm assuming that puts me around 30ml (large amount leakage) plus 15ml (if I replace condenser).

The other option is to drain the compressor and follow the formula at the bottom of page 89, Obviously there is no R134a in the system so [alpha] would be 0.

Thoughts?

Re: Replacing AC condenser on a 2016 Leaf S

I would drain/evacuate the whole system since it has been leaking (open to atmosphere) for some time. Then you can just put the full amount of oil and R134a into the system to be properly filled.

It too recommendeds "If you are operating on a system that has sat idle and without refrigerant for a long period of time (like a project car), the entire system should be flushed before attempting to recharge the system". Looks,like I can borrow the flushing tool from AutoZone.

Reading the above it seems it assumes you'll be replacing the compressor. I was hoping mine is still ok. The Autozone video states to never attempt toflush the compressor. Per the Leaf service manual there is always some old oil remaining in the compressor even after draining it.

Re: Replacing AC condenser on a 2016 Leaf S

I don't think you will have enough oil left in the compressor after pulling vacuum for extended time to worry about. Just use the correct amount for filling an empty system. A little extra oil may slightly reduce the cooling capacity, but probably not noticeable on the LEAF. The main thing is to get the leak repaired and the system fully clean and dry. Are you planning to replace the accumulator? It might be a good idea since the system was open so long. Good luck with your repairs.
