Which connection do I use to recharge the AC on a 2003 Camry? There is one
near the firewall and on near the radiator.

Cold = Lowside = Carge side
Hot = High pressure side= DON'T CONNECT THIS SIDE FOR CHARGING.

If you con'tknow what you are doing, don't. My guess is that the low
pressure fitting is near the firewall and the high pressure fitting is by
the rad. If you can run it at all, feeling the lines to and from the
compressor will tell you quick enough. Compression makes heat, so it makes
sense that the high pressure side line would be hot coming from the
compressor.

Of course, a set of gauges completely solves the problem.

You'll want to use the low pressure side for charging. Should be the larger
of the two lines and have a plastic cap with a 'c' on it. Please be
careful, and consider having it evacuated and recharged with a machine.
These newer AC systems are very finicky and will not operate well without
the EXACT prescribed weight of refrigerant.

I second that opinion. Though in the past I've recharged a/c systems (both
R-12 and 134) I've become a little chastened by what "Ray O" , a very
experienced Toyota tech said recently on alt.autos.toyota.
He DOESN'T work on the a/c on his own car, and lets an air conditioning
professional do it. That's enough to warn me off.

the charges are so small on cars these days that those cans should not
be used anymore.
the car is so new that you should have the system serviced only by
toyota.
they may be costly but one screw up by you can be even more costly.
i have my own service equipment and i would not attempt any ac work
without it.
