- '93 XLT
I am finally getting around to fixing the A/C on my old gal. 93 XLT.
I am replacing the compressor as it grenaded some 4 years ago. And converting to 134a while I'm at it.
I plan to:
Flush the system with A/C flush from Autozone and compressed air
Replace accumulator, new orifice tube, new compressor (hopefully don't need a new condenser- we shall see) and 134a valves
Evacuate with an electric pump for 1 hour at least
Check for good vacuum using gauges
Add 28 oz. 134a (85% of 32 oz. R12)
I already have everything: New compressor, orifice tube, accumulator, PAG oil, refrigerant, vac pump, gauges, etc.
My haynes manual has been little help so far, but I did learn a few things.
I have read just about every post I could find about how to do this process, and have gotten thus far: I have removed the old compressor, and begun taking things off to get to the condenser and accumulator.
I now read that I need a 'spring lock coupling tool' to get one of the lines off the accumulator as well as the condenser. Can you use anything else?
Also, do I need to remove the condenser from the truck to flush it? That involves draining and removing the radiator. Do you have to flush the evaporator as well?
I have read many posts about how to flush the system, but nothing that answers these questions.
I'm stuck without the coupling tool, and I would really not like to have to drain and remove the radiator.
On a side note, I was able to "rent" the electric vacuum pump and gauges from Autozone. I paid a $200 deposit for the pump and a $100 deposit for the gauges, which are both fully refundable if I bring them back within 90 days.
Any help would be awesome!
