Aircon problem led to car overheating

Actually automotive technicians here are trained this way. To remove and replace.
Maybe you are fortunate to have a section that will calibrate, certify, and re certify parts.
How many mechanics have proper training in metrology?
You are very lucky you have access to proper instruments that you can repair a part
back to reliable use.
As for us out there, we remove and replace and that is it.
Surplus or oem, so long that it still works.

nope, all we had was ordinary mechanics' tools. we tried to fix parts that we could, so we can use them again. you know... clean, solder or weld, un-bend, bend, adjust clearance, sandpaper, re-paint.. nothing major. no, we did not re-manufacture them. and we did it for two reasons: first, because it was challenging and fun; and two, we didn't have money to buy new parts. heh heh.
