Ac temperature differential, what should it be?
Hey everyone,
I'm heading home from my cousins in my 420sel from Columbus and its 91-95 outside here according to my outdoor temp sensor.. My dial temp gauge in the center vents reports 60..were doing about 60-70 mph.. Is that a reasonable differential? Or should it be wider? I added a bit of r12 before leaving as I suspected it was a bit low based on my readings. It was about 85f, aux fan on, low side was about 22, high side was 150-165. This was all at a high idle. I wonder if the txv could be fault? High side seems a bit low for r12 with those ambients..
