I have been planning this spring to reseal my fan motors and now to reinforce my
my radiator and fans, so I'm watching what you are doing Scott. When I am doing
the fans I am planning to send out my trans cooler and have it cleaned and checked.

I am working on a driveshaft deal with Summit Racing. Was browsing their FAQ section and ran across this about radiators, found it interesting and thought I'd share.

My new radiator looks like it's been cut with a saw!

Our CAC have the same reliefs. The CAC also is hung off the radiator adding even more weight

So finished install. About a 8 on the pain scale. Suspect each one would have to be a fitted unit. Added about 5/8 of a inch to the rear but is well protected now. Will address fan mount and transmission cooler at a later date. Fans will need resealing this year so I'm going back in anyway

I am looking at bracing my radiator and is it just the bottom part that need bracing or
do I need to go up to the hangers.

I bolted to bottom of the mount bracket on each end. Keiths new radiator came with a very robust mount and radiator was bolted to in sides and bottom. It also left 10 mm gap at the end of the radiator for expansion. I should of taken some pictures, didn't. See photos 3 and 4 for how I tensioned upward

I bet you could buy just the cradle/mount from Atlas Radiator, but I sure wouldn't want to do that job just to swap the mount.

Thanks Scott, somehow I missed reply 28. They are great pictures. I will build it the same
way. The tubing you used was it 5 x 2 and how thick.

3/16 box with 1/8 verticals and the ends were 1/4. Forward one was a pain to fit around my mount.

Thanks Scott, your tension bolts are a great idea. As soon as I saw the pictures of them
I saw how easy it will be to get the pressure that will be needed on the bottom of the
rad support.

Peter I still need to sort out a cooler hanger to replace hanging off the radiator. Was hoping to upsize the cooler at the same but the price is a lot. I did add a supplement temporary cargo strap around cooler to frame, but still need to make a support system that can be hung off the frame for radiator free support. Keiths 2003 is completely different with the cooler next to the retarder accumulator, mounting it much father forward.

I was out looking at the cooler and I agree it should be hung off the frame. Not an easy
thing to do. When I reseal the fan motors I'm servicing the transmission so I will have
the cooler checked out.

Absolutely agree with holding off till fan motors reseal, I'm doing the same

I bought the steel yesterday and I have the two end hangers made and got the tubing
cut. It sure makes easier following Scott as I didn't need to plan as much. I looked at
my cooler and as I have a Jake I don't think I will do anything with my cooler except have
it serviced. Still know idea how I will make the cooler hanger. When it's out being serviced
and and the fans are out of the way it may be easier.

Dang Peter you are hard to keep up with. So I was planning on hanging off the frame rails from above. So on my 2001 the retarder accumulator is ahead of the cooler. On the 2003 they are side by side having the cooler much father forward out of all the mess. I don't want to change the radiator lines to accomplish this and was going to work around the fans and main radiator to support. I'm thinking that it actually could hang off the top of the frame but that would mean only being on one side. Another idea was to saddle around the frame rail and have a couple of pinch bolts on top of it in shear, would be real strong, could do a post installation I think, but it has to shaped to clear fans and lines. Lot of stuff in that area. I really like the idea of being able to adjust to match cooler location as you are installing, IE several parts that fit together and are adjustable. I hope to be able to make a couple extra and would like them to be installable and adjustable in the field. I all to often make this stuff one off custom and would really like it to be more generic so as I can reproduce a viable mount. I'm glad you got ahead of this. Hopefully I'll be following soon. Build to fit and remove to build jig to build others? Hopefully we will come up with a viable mount.
Curious on what a shop can do to your welded cooler. Please update as you go. And pictures.

The Allison Dealer here is awesome and I was going to ask them where they send there
coolers to be checked.

Well it quit raining here so I got out this afternoon and got the tension bolt holes
tapped. Taking the outside bolts out took a while to get them out. I ended cutting about
1/8th of an inch off the side of a 3/8 drive socket and using a 1/4 drive ratchet I got them
out. Tomorrow I will pull the trans cooler and start the fan resealing. I will open a new
post for the resealing.

Took a picture of the socket I had to reshape so I could hold the 2 bolts that were
too tight to get a socket on. The bolts just needed to be held as they would spin

Took the cooler to a radiator shop this morning and got the cooler brackets made and
will wait for the cooler to get back to figure out where I will place them on the frame.
I have almost got the new rad support finished.

So I was daydreaming about this still. Was thinking a saddle hooked on top of the frame rail projecting out to center of radiator with a couple of large turnbuckles would suspend and be easily adjustable. Would need to figure out a 80-100lbs isolator similar to the radiator mounts. This wouldn't completely support cooler. Use add the needed uplift to take tension off radiator core. Have it attach to the top center of the oil cooler. Just thinking

I finally got the radiator support finished. I followed Scott's design and it works great.
The cooler support I screwed up in the measurements. I have the cooler too high. The supports work great. I will fix it and
post the proper dimensions.

On the radiator supports you can see the 2 pilot holes they will end up being 3/8
for the two 3/8 bolts I will use. I will tap into the frame.

So is the cooler now free and clear of the radiator? Yes there are many variables and that is why I was thinking if you could adjust in place it could be tuned for the installation. I originally thought of the rigid mount but now thinking just added support if that makes sense and leave attached to radiator support. That is why I mentioned needing it's own vibration dampener similar to the radiator two. Mine was going to be two Bronco body mounts I'm swapping out for new. Looks similar.

I wasn't going to use and mount but maybe I will make up something. When I took the
cooler in the guy there said they don't make them like them anymore. He said the cooler
should be more efficient.
