Should be right on the compressor.
Follow the low side hose back to the compressor.
If it has not been converted from PAG-46 refrigerant you will need to flush and refill.
If it HAS been converted to R-12 or 134a already - you will have to unbolt the compressor to charge - as there isnt enough clearance with the adapter installed to get the coupler on.... and it is charged on the HIGH side in this scenario... since the car is not on.
- Hookup gauge set to high side, low side, and vacuum pump.
- Open valves and run vacuum pump for 30 minutes, to boil off all
- Close valves and make sure vacuum is held. If not, there is a leak.
Then Fill with R-134a
- Jumper low-pressure cutoff switch (next to left headlight)
- Hook up R134 can to hoses (purge air from line)
- This is a good time to add oil, if needed. Pour some in the hose, the R134
will push it into the system.
- Open high-side (red) valve. This will let some of the R134 go into the
- Once you've got as much as will go in there (putting the can in warm water
helps), close the high-side valve.
- This is very important. If you don't close the high-side valve before you
start the car, the can might burst. That would be bad.
- Start the car and press the a/c switch.
- Open the low-side valve (the one going to the compressor) and let it s uck in
the R134. S uck s uck s uck.
is the TSB for conversion if you're interested.
