Question Need AC Refrigerant Capacity Info for my 2013 Please

Hello,

Apparently the A/C information sticker that was under the hood has either peeled off or faded completely for my 2013 Versa SL. I had the system pumped down and replaced the AC compressor but need the capacity information so I know how much R134A to replace.

Could someone reply with the capacity and/or add a picture of their sticker please?

Thanks so much

I don't know the capacity but you really need to go on pressure not amount.

Fill it to the required pressure. Run the unit for a few minutes and then check it again as you may have trapped some air in the lines.

You absolutely better NOT have ANY air trapped there or the work done by incompetents. The slightest amount of air then leads to acid creation in the system that eats parts and why you vacuum them down.

You DO charge to pressure but you absolutely cannot using just one pressure gauge like the cheap kits do, you use the standard two gauge setup the pros use, the ONLY way you can tell you have it right as the HIGH pressure is the key to knowing when to stop.

The capacity amount is WORTHLESS once the system is tampered with, the new compressor needed more oil and that likely will be an incorrect guess amount unless the oil in the other one was drained and measured 100% accurately. ANY guess there means your Nissan capacity number is no longer valid, that number only works if the exact amount of oil is KNOWN too be in the system still.

Why you charge to pressure, way too many overcharge or undercharge thinking they have to have a 'certain' amount there and then the system does not cool well. After 40 years of doing my own I can tell you by using pressure it does not matter how much goes in, it can actually be too little by a few ounces and still freeze your butt off with the end result.
