Jeesh, I can't keep CAC's in this damn truck! I've had this truck since new, 12/09. The first CAC lasted 3 years, and since then it's been every 2 goddam years! Almost like clockwork.

make sure all your bushings are good and that things are not over tightened. That whole front structure needs to have a bit of give to it. Also when installing new, don't force any screws into their holes if they do not align up perfectly. Grind out the hole in the frame instead so that no stress is applied to the CAC or radiator.

Lastly, when opening your hood, don't let it slam open. This will kill a CAC in a hurry and I see lots of guys do this at the truck stops while shaking my head every time.

You also haul heavy. There is likely some twist in the frame when pushing things hard so make sure your lower front structure bushings are in good shape/not bound as well.

I always use new bushings when putting them in. I've actually found the OEM bushings are crap and don't last 6 months, so I use neoprene glad hand bushings IPO on the four collars. Four hook bushings come in the universal kit, and I only have 2. They never show wear, but I change them anyway.
I NEVER slam a hood, and I'd be right beside you shaking my head too when I see that.
This T800W rad and CAC is ridiculously wide, and I think that it's actually too wide. The C-500 uses the same rad, but vertical. They use a different CAC that won't work for me, and the sister company has many of them, and they just last forever. But they have the same trouble with the 2 WH's they have.
Because I'm usually under torque, twist is just a fact of my life. I've just gotta live with it or find a different truck.
This stupid CAC on this thing is my version of the Prostar A/C. It's the flaw that is my Achilles heel unfortunately.
