I had my 92 mx6 re-gassed for the first time since I bought her she was unconverted and still running r12 or not as when it was tested the system had no pressure.. Anyhow the guy vac tested it and filled it with a compatible gas?
To my delight I heard a click under the bonnet and freezing air pumped into the cab I was chuffed as sh1t. The following morning I heard a disturbing clicking coming from the ac pump that evening it stopped working. I had a place called coolit in winterbourne abbas look at it.
He was able to not only tell me but show me the various leaks of oil coming out of the system at the front the dryer and something else maybe the exchange anyway he said it'd cost £340 quid to fix.... Too much for the 20 days a year it's hot enough to use it
This guy btw used to work for Mazda and knew a hell of alot about my 6 he was telling me about an early recall with the 6's causing trouble because people wern't fitting the rear vcg back properly! Can't remember what the recall job was though.. Shame he doesn't do other work on em' Only charged me £25 quid to diagnose.
