hopefully someone out theres got pictures or can take pictures of a few things so i can install my new under bed trans cooler this weekend.

i need pictures of how the cooler mounts under the bed, and plumbing from the trans to the cooler etc.

also i have a question. when a truck came with the under bed cooler and fan assembly, was there a small core cooler mounted up front also? beause i bought one and its not the one i have in my truck now its like half the size and has 2 lines coming out of it like mine does. i have the U shaped one that has a small dent for the hood latch to close.

also whats the best, simplest way to operate the fan on the under bed unit? besides a switch that is, idont have my gauge in yet so im not qutie sure what to do as far as a thermostat etc

I have the dealer installed auxilary cooler under the bed. I have a aftermarket transmission temp. gauge, so I decided to rig a toggle switch under my seat to manually turn on the electric fan. The electric fan seems to help a little bit. I have a picture of my auxillary cooler, I will have to check and see.............

If you have a brand new Mopar underbed cooler it will have a temp switch built in it at the cooler itself. I installed one of these on one of my dads trucks. Its super easy if its new you will have detailed instructions. You have to drill 4 holes into the cross beams under the bed. Then to splice into the factory line you simply cut it right in front of the pan (I believe its been a couple yrs). You install elbows with a brass fitting (supplied in the kit) and run the 2 rubber hoses over to the frame and run them right back towards the cooler. Its seems like alot but it really isnt that bad. Took me about 2.5 hours taking my time. It was an immediate improvement!!! In this truck you could watch the temp guage rise then when the fan kicks on you can watch the guage fall back down. Very nice inhancement. I just wish he would have installed it when he bought it new. Along with a dash mounted tach

Firstgenfanatic- can u take more pics of how its mounted?

Freight train- what did you need to tap in your lines? And what did u use for hoses?

The brackets on the cooler go to the rails on the bed, mine has a thermostat inline that kicks the fan on at 190. This is the best I can do with the truck tore apart.

canyon express. thanks i got a general idea of where you at with the cooler. i was looking and im thinking im going to cut the OEM plugs off the cooler and put pig tails one beasue i dont have the factory wiring harness with the plugs.

also is there any notifications of the IN and OUT of the lines to the cooler?

DNR Customs, good idea with the grate.

Check out BC847. He did an install and write up. That might help you out.

I actually forgot that I have a copy of the original factory installation instructions. Hope this helps some folks on here.
