A friend of mine runs a 5.0L Ford V8 runner,he tried several different electric fans,radiators ect. none kept it cool during slow speed wheelin here in Az. A factory V8 Explorer fan clutch and radiator solved the problem. Electric fans dont seem to pull enough air. Dont even mess with any Toyota
Radiators. Even the V6 was no help.

Running a 1370 (17 inch) flex-a-light fan off of the water pump. Howe 19x21.5" alum rad.with custom shroud, and stays cool ok. Hot 90 degree pluss days with air on and as long as I am moving stays around 185 - 195 degrees.

It only wants to creep up is when the possitive pressure under the hood makes it less efficent. When moving there is enough vacume to cause better air flow. I might cut some out of the wheel wells and put a blower under the hood to suck the hot air stuck in there from the hood being closed. My radiator is under sized for the motor I have. This fall will look into getting something with more surface area exposed to incomming air.
But no I have not had this motor go over 208 degrees.

Brandon, if you have a pic of yours mounted in/on the flatbed, could you post a picture por favor??? Also, how did you plumb the lines? If you have or could get a pic of the lines I would be interested in seeing that as well, I have seen pics of others and they seem like they could get damaged fairly easy by rocks....maybe not though.
Thanks

pvstoy,

Where did you get that shroud made? or did you make it yourself? I tried to make a shroud using instructions in one of the "off-road" magazines, but it didnt turn out too good. I like your design alot better.

just re-read and you said the lines - the copper is above the frame so I think it is safe and I found this cool tape to patch as well as epoxy..

So you are using copper pipe, like from a house??? (atleast thats what it looks like to me, my bad if I am ingnorant about that) I didn't know you could use that for a vehicle, well, never really thought about it either I guess. Cool idea, if it works.

As far as the radiator itself, is it getting any air-flow where it is mounted other than from the fan? Looks good.

I have a 350 chev in my truck with the regular fan and a three-core radiator out of a camaro.. the only problem is that we had to do some cutting to move the radiator away from the motor. Because of this we lost the latch and all that crap to hold the hood down so I use pins on each end...but that's just what I did... electric fans are a waist of money if you ask me

Sure it does, vacuum effect when driving down the road and on the trail it will get a LOT more air than one stuffed behind a grill and a winch..

Tell ya the truth I have not even needed the fan yet though, with so much tubing/hose and that big rad it hasn't got hot..
