DIY recharge A/C: how much different (if any) Is procedure on Leaf than regular ICE?

Wed Jul 29, 2020 12:22 pm

>> From your description, it sounds like it may be low on refrigerant

Sorry if this has been asked before.

Our 2015 base model Leaf with 52K miles is not putting out any cold air from the cabin vents. I thought I would try using a recharge kit with R134+ that includes sealant before taking the vehicle to the dealer.

I've watched several YouTube videos, and the procedure seems doable (famous last words?). However, I thought I would first check on this forum to see if the procedure is different, since there isn't an engine running that is turning the compressor.

Thx ...
2015 Leaf S. Bought 2 year lease turn-in with 14,500 miles. Drive about 14k miles/year. Most charging from 'free juice' at nearby ChargePoint or Nissan or other free L2 public chargers within walking distance. ICE is rarely driven pickup truck.

I would not use conventional "sealant" in the system because the compressor is hermetically sealed and runs on traction battery voltage so the refrigerant and lubricating oil must be compatible and have adequate electrical insulating qualities to avoid battery ground isolation issues. The system in the LEAF is more like a high-efficiency, variable-speed home system except the supply voltage is about 400 volts DC instead of 240 volts AC.

My understanding is that the Leaf does not use r134a, but uses ND11. You would absolutely not want to put the wrong refrigerant in the car.

My 2013 S model uses R134a refrigerant and AE10 oil.

I looked under the Leaf's hood, and found a decal indicating the A/C uses HFC134a refrigerant and AE10 non fluorescent oil

S uses AE10 oil while SV and SL (with heat pump system) use ND11 oil. Both systems use HFC134a refrigerant. I would not use leak detecting dye and/or sealant because they could reduce the dielectric strength (electrical insulation) level of the refrigerant system.

Idallan- best let a shop handle the a/c charge.
Reason being they will at the same time check for any leaks and repair if necessary.
In addition they will recharge with the correct amount of Freon and oil.
Something that you can't accomplish with the DIY can.

I would pull out all the refrigerant and then charge it.
The leaf doesn't like to be over charged.
