This is a LONG story that I'm going to try and cut short.
Last week I blew out all lines with air and solvent(front and rear evap, all lines to/from rear)
Put in a new fan clutch (aftermarket brand)
Followed that up with vacuum test - all good
Filled with 60oz and 8oz of oil(assumed that there was 1.5 in compressor and 1.5 in condenser)
COLD AS ICE.
3 days in use, it was 88 degrees and I'm sitting in the cul-de-sac waiting to pull into my garage and the pressure relief valve starts blowing refrigerant
Not that this is totally relevant, but this behavior has happened before. Prior to all that I described above the compressor grenaded and I followed that up with a complete rebuild of the system. (all new components top to bottom) and after I got everything up and running, the pressure relief valve started doing the same thing. So I evaluated everything, then the tranny went bad and it sat for 3 years. New R&R on the tranny, new dryer, and start over with my opening "Last week I blew out all the lines..."
Could this just be an issue where the fan clutch is not cooling enough because it's aftermarket? Could there be a blockage in the condenser somehow? Faulty expansion valve? It's hard to reproduce...it doesn't always happen the same way every time, but it always stops as soon as I turn off the A/C.
