Relocating the radiator

[FordGuy]

Rick, it will work fine. The trick is to make sure there is adequate space in front of the radiator so you fan can draw air without restriction, Hell if a 900HP Trophy Truck that weighs 6500lbs can stay cool in the rocks with outside temps reaching 110deg you should be good to go.

I would be concerned with loosing rear visibility, unless it's mounted very low. Like Rich says Trophy Trucks do it all the time but they are completely covered with shrouds......SANTA

There are some nice radiator, fan , shroud combinations out there right now.
When I put the Subaru engine into the sand car I was worried about rear visibility because how high I wanted to mount it. At least in the sand, it wasn't a problem.
The new cage will be designed to handle a rear radiator, but I won't be committed to it until later in the project.

This is going into a buggy build, so cab head is not an issue.

I dono about you Rick, but cab head is always a design issue for me :scottm:

Isn't the basic design of most cab's goin' to give her enough room anyway?

because it's not in the direct line of airflow. Like I said it's not right but it works.

You can run a bigger, rad, more fans, more cfm to compensate for non ideal design.

Sounds like you have already made your mind up and want to do it so go for it.

When you are crawling on the trail, is there really that much airflow going on anyway? :dunno:

He was just pointing out what the ideal location is.
I've seen a few radiators pushed into fans and winches before, so I'm
thinking that ideal air flow might just take a back seat to ideal protection.

Not sure if anyone pointed this out but think of all that extra coolant capacity. That would help keep it nice and cool. I saw a guy that used exhaust tube and just used hose to adapt it to the rad and engine.

In my limited experience I have only seen radiators pushed into mechanical fans when motor mounts failed. I assume the same could happen during a roll, but assuming you do put it in the back it would be much more protected by whatever body you have left/roll cage.

Have you thought about doing a Lexen "firewall" between the radiator and the seat backs?

Rick you shouldn't have any problems Jason is running his in the way back with the 4.0

 

[FordGuy]

That is a nice spot, low and away from the driver/passenger.

one if the things to remember is the radiator fill has to be higher than the highist point on the engine so you can bleed the system. and of you need more flow

you can always install a inline water pump to help the stock pump

Excellent Input!! I like this idea!

I was thinkin' I would need an additional pump (or just remove the stock pump and add the electric pump.)
There also won't be a problem with the radiator fill being higher than the engine....

I hate the sound of electric fans running behind me.

 

[kingmeirl]

I am a plumber and dealing with circulation pumps I can tell you that you will not need a new or bigger pump. You are pumping the fluid horizontally and no extra energy is required. The only reason you would need a bigger pump is if you wanted to increase the flow rate (gallons per minute) or if you needed to pump the fluid higher vertically (called head).

Don't worry buddy, mine will be in front of you!!

Maybe at the start, but I'll pass you when you flop!
