So i was driving my car around back from the mall its like a 15 mins trip. i turned it off for like 45 mins and started it again. It was about 85-90 ourside. When i started it i here this PSHHHHHHH sounds just like a NO2 purge and then a white cloud comes out from under the car. The cloud does not smell like any thing and is just white. It comes from i think under the right front part of the car. I think it may be r34 the stuff for ac. But i had one of thoes blow up at me at work and it was a yellow cloud. if some one could tell me what this is or have another guess at it that would be great.

The fisrt time it was yellowish because the lubricant was blown away with the refrigerant. Apparently no lubricant was added when the system was recharged after the hose belew off, so the second time the hose blew, the only thing that came out was straight refrigerant.

well the AC is still working so now i dont know waht to think. except to get the levle checked
