Re: 2004 Frontier AC stopped working today

Today (Arizona) I stopped at Walmart to pick up some pure R134a cans at $4.88 each; I noticed that most cans had a new self-sealing feature I hadn't been aware of, that apparently need a special/new type of can adapter. I found behind these cans some old cans that were of the sealed style, so I ...

Re: Cant add refrigerant

Wanted to addd a can of gas but suction line wll not suck in. Maybe its the connection valve on the line on the guages. Can I now test to see it it is a bad pin on the valve? Can I depress it with a eraser from a pencil? The can is now punctured, so I can not simply unscrew the end connected to the ...

Re: Can PAG and mineral coexist in old R12 system?

GM brochure GM-0011 indicates that removal of mineral oil during retrofit (mostly paraffinic in GM's case) is not recommended.

Can you attach or scan or link such brochure, I'd like to see it.

Actually, I'm surprised that GM would even address such conversion to R134a, figured their official ...

Re: over charged, undercharged I dont know.

Yeah I was talking about blow out the condenser just to see if it had a blockage of any kind. Doubtful.

Yeah the 2.5 cans if my notes was correct, was working, but who knows if that was correct. I have learned so much since then.

Today this afternoon, it was just not cooling all that well and it ...

Re: over charged, undercharged I dont know.

However in my notes when I first did the 1988, I seems that I wrote down that I used 2.5 cans. That would be over charging but it sure did cool well if that was correct. I am not wanting to try that now as the pressures on the high side get crazy high.

2.5 cans is too much !!!


Maybe I should ...

Re: over charged, undercharged I dont know.

I can't see why a new compressor could be a source of higher temperatures or too-high pressures.

At this point I think I'd recover refrigerant, pull good vacuum, and add refrigerant by weight, to make sure that you're not overcharged. What year are your B2200s? It seems that these can have ...

Re: over charged, undercharged I dont know.

Did you backflush the condenser with solvent to flush out any particles? And use a new drier?

Re: 2004 Frontier AC stopped working today

It is all import parts anyway, and the 2004 Nissan was the end of the V belt compressor. So by now any new compressor is an import from a 3rd party supplier - and WHO you buy it from is more important than where it was made. If you buy from a reputable supplier that will be there tomorrow, they are ...

Re: 2004 Frontier AC stopped working today

The good news: the AC idler pulley is fine, the AC clutch is fine, the Gates AC belt is fine.

The bad news is that the compressor is locked up tighter than a drum. This Frontier uses a DKV14C Compressor; and since the condenser is parallel path type, that will need to be replaced too, as any ...
