Well those spring arms, went right through the front of the cooler! I have had this hood down like this before and it never did this. hell, it almost took out my radiator too. The hood was not that far down, no where near 90*. Oh well, how difficult is it to replace that cooler?

It looks easy enough to remove the unit itself, but I crawled underneath and was looking at the plumbing where the cooler attaches. How does that attach to the lines? Is there soldering involved or are they more like a hydraulic line?

HELP!

When I replaced my CAC, I removed the front plastic grill (3 screws and some clips) from the outside of the hood. I then removed the hood shock from the top of it and rested the hood itself on a 55 gal drum. The hood does not like going all the way to 90 degrees!. I then took the boots off the CAC and removed the condenser for the A/C and gently rested it up on top of the motor without removing any of the lines. I took out the screws for the coolant reservoir tank, then removed the CAC unit itself. It took 2 people to carefully wrangle it to one side of the truck, but it was not heavy at all. Like you said, it is small.

I would not mind making a video of it for a prostar with someone some time. I think it would be good to talk about replacing one, why they fail, and all the things to watch out for when installing the new one, etc.

That is what I did, pulled the grill and did as you did, on a garbage can, but I think my can was a bit to short. Pissed me off, as I have done this before, but with a taller can. I did not realize those hood thingies went in that far. Live and learn. Good thing those coolers are inexpensive when compared to the other parts. How does that thing remove? Are there wire clips holding the lines on like on a car?
