Need to add a can of R134 to Toyota Camry - Microman - 06-20-2011
I have done it before.
If I remember correctly the hose will only go on the one side of compressor.
What was that LOW PRESSURE or HIGH PRESSURE side?
So you start the car after can is hooked up, and then start ac, then open can, and it sucks it in, right?
Can sits upright? Can gets cold, and emptys. Car AC is cold again.
Any other precautions?
Thanks.

Low. Low. Low. High pressure connection can result in exploding can. I'd so a search to see if you need to add r134 in gas (probably) or liquid form. Watch the sight glass so you don't overfill.

Read... The... Instructions.
And note.. AC systems are 'closed loop' systems. If you have to add R-134A, it means that sucker has a leak. Which means other bad stuff is happening, EPA, Federal law, ozone layer, yadda yadda yadda.
Most 'top up' kits nowadays include a nice cheap little gage that will tell you if you've got 'enough stuff' in there based on the LOW PRESSURE side. And a safety "Blow out panel" on the can if you accidentally hook it up to the high pressure. Which can still hurt you. So be careful.

What cbelt3 said. You need to fix the leak first.

I believe the high side and low side had different type of ports anyway (at least on Honda), so the refill hose should only fit on the low side.
I would suggest you buy just R134, not onr of those with "arctic" crap, I did so and damaged my AC. learn form my mistake.
I would also suggest to use the pressure gauge to check the pressure on the low side port, make note of what it is, and then add R134. Do not add too much. if in doubt, add just a little (a few PSI) and see if the AC runs better. If you add too much, then you have a whole different problem.
Yeas, you would be better off fixing that leak. My car was runnign fine for 10 years until one hose was damaged by a sharp edge which it was not supposed to touch (that's another story). the other car was running fine for 13 years until I tried to add some R134 left over from when I tried to fill the 1st car, and then I think i added too much and the compressor started to make a weird noise. I had to let some R134 out and now it seems better. No more noises.
Wear safety goggles and gloves.
good luck.
