QuestionThe AC system has a slow leak and was converted to R134. I think the high side and low side aftermarket fitting were switched. There is a fitting(now marked HIGH) on the drivers side next to the top of the front shock tower. The other fitting (marked low) is behind the compressor. Are the fittings marked correctly?
Also, what does the book say is the time alloted to change that oil pan gasket seal?
Thanks for your time and effort.

AnswerHi Gene,
Today, you've caught me in my weak area. I keep saying I should learn about air conditioning, so I can fix it on my wife's car, and not go thru every summer hearing about it. But other priorities always seem to get in the way. And there's some special equipment only really useful for a/c systems that I should buy first.
All that's a long way of saying I don't know about your fittings. What I can say is that the compressor has both high and low pressure lines leading to and from it. Often these lines are sized differently because of the significantly higher pressures run on the high side.
So, the high pressure side, where you'd expect to see a high pressure fitting is somewhere in the line between the compressor, the condenser (the second radiator, if you will), and the evaporator (inside the passenger compartment). When the evaporator sends the r-134 back to the compressor again it's at low pressure.
Once you track these lines it should be obvious if the fittings are switched.
As for the oil pan...I don't have any use for the "book". If I had charged my self an hourly rate for all my work I'd be a rich mechanic, but I would have been fired at some point for being too slow.
