What is everyone's thoughts on rear mounting a radiator? It would have to be leaned forward over top of my fuel cell so I could still see out my rear Window, then I would have to add a remote fill to my cell which I want to do anyway. That would save me having to rework my front winch mount for space.

I'm looking at moving mine back there just to get a better approach angle.

Good fans and its not a bad plan I would think.

Agreed. And trophy trucks and short course truck do it too. So even more street cred.

Move your cell back a couple inches and it vertical between cell and cab.

You can lay it flat all you want... Just needs fans to move air through it...


Better question yet what is your budget for this radiator fan setup? Cause a lot of drag guys who kept the radiator have them made with custom shrouds and they aren't too expensive by the time you all it all up... Almost same in price...

Here's how we set up my friend's truck. Don't know how well it works since it isn't done yet, but we figured having the radiator in back of the cell with the fan pointing out would limit the heat soak of the fuel tank.

His fuel tank was made to be tall and narrow from the side view so that it wouldn't take up much space in the truck bed.

Not trying to be a dick at all just giving you a heads up since I been down this road... Don't do it like that unless it will have tons of air flow...

I will be doing something like that, but my battery is behind my fuel cell so it has to but up higher. The fan in the picture is opposite of what you are describing right?

CTB2, the cell is too much work to move, I have to build around it or over it. I ordered that summit radiator, it is 19" tall so I should be able to only lean it a little and still see over it, put it just behind my fuel cell, maybe over the battery and cell? IDK yet.

So explain to us dummies what the problem is? Will the cell limit the air flow?

I had mine about 3-4"s off the back of the cab using a pusher fan mounted on the back side so it pushed air through the rad. and against the back of the cab. Never had any cooling issues because of it.

Bleeding all the air out can be a pita but not bad, only other issue I had was I once broke a strap extracting somebody and when it came back to the truck it hit the fan breaking it.

Easy I'm not calling anyone idiots or anything... We had a problem with a few different cars when a fuel cell or batteries when blocking airway to the radiator, the fans weren't operating at max proficiency...

Air in general is comfortable moving at a 45 degree angle from a point/edge/wall in general. So if u can hold it far enough back that air can pass the edge of the cell at a 45 degree angle and hit all of the radiator at any pointyou will be absolutely fine.
If you sharpen that angle to more than a 45, you will start to add additional pressure drop to the radiator fan causing more load etc..which will cause premature failure and a loss in overall cooling performance.

Just food for thought and im NOT calling anyone an idiot. .lol

Knowing kyle, he will make it fit there, operate and look as though it was supposed to be there from the factory.

Whats the dimensions of your radiator? You can add a safety factor, by making sure the radiator face area is equal to or greater than the cubic inches of your engine.

Woot!
Can't wait to see full hydro on this biotch!

I would have to look through my old build thread but I believe it was bones that warned me about running a radiator and fan on a 45 degree angle. He had a big problem keeping electric working. It was hard on the bearings or whatever being on an angle like that. It is the buggy build thread somewhere. I have no experience with it so I am just puking up somebody else's knowledge..

Yeah, either him or hose jockey.

After having serious discussion about it tonight, I may try to mount it in the front still. Winter project.
