I have to replace my left side coolant hose - the A/C compressor jumped out and bit it! I'm having a shop do it for two reasons: 1.) because I don't have a way of catching coolant at home and 2.) as a means of meeting a new mechanic in case I need something bigger performed locally in the future. I do not have a self bleeder. Question: what advice should I be giving this mechanic regarding how to replace the hose with the least amount of coolant loss and, how to bleed the system afterward? Thank you.
