Any A/C gurus out there?

Fwiw I've got 63 ambient and 48 at the vent.

Oh, nevermind!!!! Just went and drove it hard. Came home, it took the rest. Compressor stays on. The FSM doesn't recommend pressures at 60F but I'm at 30 low and 150 high which jives. Oh, and now it's 39 at the vent.

Low side pressure should be around 28psi off to 38-42 back on, you look like your good.

, I have considered that they may have been counting on some of the heat gained through the uninsulated lines in the engine compartment, which I recently insulated. There's no other explanation I can find for putting 3 feet of 2-phase line (between the orifice and the evaporator) through an engine compartment

I have often wondered this too, I have seen many passenger cars with the orfice near the condenser where trucks and vans seem to be in the inlet of the evaporator. I don’t know if this is packaging or due to evaporator size.
