I know the the theory of refrigeration but not the execution.
I find myself with three vehicles that need service. I have a case of duracool and a cheap 1.5 CFM vac pump.
Now what?
- last winter the ac compressor on the Expedition went out (at the bearing, no contamination) We installed a new compressor and left it until now.
- last week i had a small bump with hte Civic and cracked a line.
- If i'm successful with these two, i'll take on the coach.
Questions:
- did all the oil leak out with the R134 in the Civic? It was a small crack half way up the condensor?
- Absent a vac gauge, how long should the pump run to evacuate the system?
thanks
