Engine off AC off


Engine on AC on



After running rpm to 2000 momentarily not much change




Engine still running AC off




Disclaimer: I don't know anything

It looks to me though like a restriction in the system. However doesn't it look like the low and the high are trying to equalize somewhat quickly?

Watching videos etc I thought if the expansion valve was stuck closed it the high and low side pressures would take a while to equal back out.

Any suggestions welcome thanks

 

Oops sorry

2015 gas super duty 6.2

 

you are very low on charge. engine off and engine running ac off readings mean nothing.
i charge by this chart:

 

Yes sir thanks I think I will try to add a can if you think it's a good idea

 

my bet is it will take 2-3 cans.
AND the compressor clutch must be engaged, or it will not take any refrigerant.

 

Yes sir thanks

 

Thanks Boss

Put in one can

Sorry that's all I got before I saw your reply




Hope it doesn't leak out.

I guess time will tell.

 

those look good. hopefully you do not have a leak.
