Mishimoto web site (
link) says the cooler in my truck is "integrated with the AC condensor".
This was apparently introduced for 2014 in the spirit of (forgive my sarcasm) "pay more, get less" or engineering "optimization" when cost is king.
Regardless, Chevy has no option for me.
Derale does make a deep pan with cooling tubes so I'll ask the dealer about that also.
