70. I'll reconnect gauges when it's 80+ air temp and report back.

Thanks again!

I have no idea if it's correct at this point. I got the full 12oz of the first can in and 3oz of the second can. Compressor was running most of the time.
I don't recall what the gauges were reading. Should I hook them up again? What should I expect to see?
A/C seems to be working fine, at least ...

I doubt it was the valve. The compressor shutting off could have been due to the thermistor on the evaporator sensing that the evap was approaching freezing. Also, once the system pressure reaches about 70 PSI with the compressor off, the refrigerant will stop flowing out of the can because the ...

They do almost always ship the compressor filled with the required oil amount for the full system. But 1st startup in the assembly plant is usually very special, takes place with the ECM being controlled at end of line tester, and they start the compressor with a sequence that gently, slowly ...

Right...presuming you now have the full 5 ounces of oil installed, assemble the system, pour in the dye in the proper amount and in a convenient place (like into a hose end, then reconnect same), evacuate the system well, verify that it holds vacuum, then charge it to specs, check pressures and ...

If it's an all-in-one unit, the electric motor that drives the compressor is housed within the same case, which means that you won't find an external shaft or flange to rotate as you would on a clutch-type compressor. The former is what I thought it might be.

No worries. I appreciate the ...

Thanks for the help.

Yes I was concerned about the ability to add all the oil in via the yellow charge hose. It seemed impractical/messy etc.

When I had the compressor removed I don't recall seeing any way to turn the compressor by hand but I will recheck. To remove it the right front wheel has ...

I've read the Evacuate and Charging procedure here.

I have a Nissan Leaf S electic vehicle (no heat pump). All the R134a has escaped.

I'm replacing the condenser (it has built in dryer) which had supposedly developed a crack but I have my doubts (but the system has been open to atmosphere for ...
