Freon use was stopped in 1994.

I picked up a piece of metal that punctured a hole in my condensor and had
to add 134a once I removed, repaired and replaced the condensor.

There is a pressure switch in the system that will not allow the
compressor to engage if the system 134a is low.  All you need to do is get
a low pressure gauge with a filler port.  The port is where you screw on
the can of 134a.  You can get the deluxe set of high and low pressure
gauges, but the high pressure gauge is only needed if you are trying to
determine if you compressor is going bad. Once you add the first can of
134a, the pressure climbs and closes the switch.  Turn the car on and
select the coldest temp and the maximum airflow.  My car is digital
control, so I just set it to 'Auto' and turn the temp down to 60 degrees.
Just monitor the gauge and remember to keep the can right side up so you
are suckin' 'air' and not 'liquid.

When you add the 134a lubricant, you will invert the can so that the 'oil'
will flow directly into the low side.  You may notice the car run rough at
this point as the compressor is chewin' on the oil.  You shouldn't need to
add lubricant unless you have a major leak.  Just follow the directions.
You really can't screw it up.  The low pressure gauge and filler will only
fit on the low pressure side and the only bummer is that on the Intrigue
the low pressure filler valve is on the firewall area right behind the
engine, so you will be working over a running hot engine.  The small
consumer cans also 'freeze' up especially in high humidity.  You may need
to fill the system until no more flow and then disconnect the can.  The
134a will not spray out unless you unscrew the can.  The quick disconnect
will keep the 134a in the gauge.  Once the can warms back up, then you can
start again.  To be honest, I never did get enough 134a into the system to
reach the 'normal' arc on the gauge.  Didn't matter tho.  2nd coldest car
I ever owned.  Best cooling car was a Ford LTD with a 351M/400 cu in. Eng.
9 mph :-(  Good luck!
