anybody else have this going on? is it normal for the 2nd gen trucks?
i looked at the setup of the radiator, intercooler and condensor and notice dthat since we have only one engine driven fan, it may be too hard for it to pull air all the way through 3 cores; enough to drop the temp in the condensor enough while sitting.
i was considering a 14" pusher fan on the outside to help drop the temp/pressure of the condensor.
comments?

Mine does the same thing, but when it wants to. when i back off the throttle it will begin to stop cooling or when i am idleing it will do it then to. when i begin to put the motor under a load it will begin to cool again. when it did it one time i popped the hood and looked at the compressor and the clutch was not engaged. i think some compressors have faulty clutches and disengage and engage at random times. i haven't done anything about, it just does it on its own. you make have a bad clutch and just depends when it will fail?!

Alot of times the Low side pressure falls to low and the compressor dis-enages or that the low side pressure gets to low and the evaporator starts to freeze up and the low temp switch shuts it down... Either way low presure does cause these problems...

viscous fan clutch is the problem. I have seen this way to many times. dont waste any time or money on anything else untill you replace it.

good tips. i'll hook up the gauges and check, but i'm 99% sure everyting is operating normally.

very possible. i'll go check that too. if i have to replace it though, i'm just going with dual electric fans.
