'12 Ram 2500 Noise/Smoke

[bills122500]

I have noticed twice now on my 2012 Ram 2500 6.7 that if it is idling with the A/C on max occasionally there will be what sounds like a electronic solenoid kick on & off and a puff of white smoke come out from under the front of the truck. It has no odor and dissipates quickly. Has anyone else experienced this problem???. It doesn't do it all the time

Not sure if the rams have it but I've seen this before when the high side pressure in the AC line gets too high. It's a "relief valve" so to speak and is like a last resort for the pressure being to high. It's just a brandade though, I'd get your AC system checked. Something else would be causing the problem.
