Ok, I have done the install and will post my results.
I followed the directions from coolerman with the advice from OffroadX to tilt the radiator back. I prefered to have it mounted only on the A/C condenser rather than ramming the rods through the radiator. It worked great, except for the fact that I have large arms and I scraped the crap out of them between the top of the radiator and the body while reaching to the rods at the bottom. As you can tell from my previous post, I used the Imperial 243007 from Advance Auto. It is the same as the Hayden 677. I mounted it with both nipples facing down so I had more open space above it and more room for the hoses to go under the radiator mount. I don't do much rock crawling so crushing them isn't a big concern.
Other than just giving the horn bracket a slight bend to keep it away, everything fit fine and went well, EXCEPT for the hose clamp at the return side of the radiator! I could
not get a screw type clamp tightened on there! There is no easy way to get a screwdriver or anything else in there. I finally broke down and used the factory "spring" type against my better judgment, but I had messed with it for an hour already with no luck.
After installing it and test driving, I didn't find any leaks and am quite happy with it and ready to tow a trailer next week.
Work time total= 2 hours (one of which was on one hose clamp)
Price= $49 for the cooler $1.50 for the fluid
Difficulty level= 2 (out of 5) not very difficult
