I finally converted my A/C, how cold should it be?

It wasn't spraying that hard, it was a very faint hissing. Tried it today and it'* totally empty. Yesterday the compressor didn't cycle at all, today it was ON OFF ON OFF ON OFF about that fast. Oh well i tried. Back to good ol' 4/60 cooling. Lol

No it wont cause any damage if it leaks out. And since it was the r134a it is not even supposed to be that bad for the environment either.

The only thing is that your compressor will do exactly what it was, it will turn on to try and get pressure, but if the freon is low then it will turn off. Then when it gets too low, it will just stop cycling all together.

I'm a day late & a buck short, but....
I made a gauge to attach to the low port & check pressure for mine. It all started when I fixed a leaky line. I replaced that & got one of those conversion kits. It had 3 cans of R134 & 1 of oil. I put it all in & it just didnt seem cool enough. I added 2 more cans (the bigger ones with stop leak in them) because I figured I didnt have enough R134 in there (it was 100% empty to start with). Well, the air really sucked them! I had wayyyy too much in there....

I used a old fuel pressure gauge (0-100psi) & a extra recharge hose I had. Just cut off the "can" side of the hose & attach the gauge. Plug it into the low side port & start the engine. What your aiming for is about 35-40psi when the a/c is on full blast. I'm not sure if this is where its "supposed" to be at, but I cheated & looked at the more expensive R134A cans with the little gauge on them & 30-40psi was the "good" zone.

I've used this method on my car & two friends cars, they all blow nice cold air now Anything over 40psi and it doent work at idle. Below 30psi & you compressor is going off & on constantly.
