Time for A/C Rebuild

Some of that may just be from running down from above.  But it does look bad.

What did the A/C shop say?

Went to Diesel Parts (they do custom A/C lines, hydraulics, etc…..)

They said the line they created was not crimped properly.  So they recrimped the line and gave me new o rings—no charge.  They thought it was leaking from the top, and squirreling around the fitting and dripping on the metal line.

Anyway, filled with 2 cans yesterday until the compressor remained ON.  I stopped there.  Pressure was 35 on low and 200 on high, steady.  

I have no sticker so I am guesstimating here.  The 1979 truck with same setup at the pic-pull said 2.75 on it’s sticker.  So I am thinking with the 80% that is correct?  80% of 2.75 is 2.2.  If I have that calc correct then I am in the field of range.

The proof of this is I went out this late morning and turned on truck and A/C.  The compressor kicked right on and engaged and never cycled off like it has in the past.  Cold air blew right away and consistently.  

I would say this is fixed…I hope.  Time will tell!

Have to say, I am quite a believer in the dye method over the electronic sniffer.  Mine was blowing false positives all over.

I've always filled to the correct pressures and not worry about how many cans or weight.

But if you have cold air, then you are doing well.  Hope it doesn't leak this time.

You may have already seen these, but there are all kinds of charts online for the pressures at the temperature.

Thank you Grumpin!  I am for the moment all within spec on pressures.  What a relief.

Started up the Yellow Rose today…..cold air blows, and it is a beautiful thing!!!!!

Excellent!!!

Awesome! Hope it keeps on cooling!
