Motor Swap - Step 7: Cooling

I did a bit of research on this subject and decided that it was obvious that I was going to need a new radiator...so I searched and researched, and found a great deal on an aluminum 3 core (.75" thick cores) radiator from "RAND" on ebay.. I figured it was only a couple hundred bucks so i would give it a try, I called and emailed a couple other people that I knew that had bought these for their Jeeps and Pickups running big V8 motors and asked them about it and they ALL said it was a great buy and they never had problems.  So, I dropped the coin and got the unit... from initial inspection, it looked great to me, we'll see in the long run how it holds up to this 375 HP 5.3L I'm putting in my rig. Here is what I did to get it mounted, and what I used to help with cooling for this shiny new addition.

If you read the "82 CJ-7 Buildup" section, then you know that I purchased a Ford Taurus electric cooling fan for my Jeeps motor...  Well, I never was really happy with the way that I had chosen to mount the fan (hayden radiator holding zip ties). I decided that when I got my new radiator, I was going to use that fan again, but mount it to where it was much more stable and would NOT ever move around so as to damage the fins on the new aluminum radiator...

Before I could actually mount the fan to the radiator/grill, I had to put the fan where I wanted it to sit on the radiator...here's approximately where it ended up:

Now that I had it placed, it looked like it would be pretty easy to mount it with a couple of pieces of bent sheet metal using the same bolts that mount the radiator to the grill.  I headed to Lowes to grab a piece of sheet metal and cut out a couple of pieces to match on each side...one side I bent by hand:

The other side I marked up and gave to a buddy of mine to bend on his familys sheet metal break... then I took both sides and painted them black to match the fan and not stick out like a sore thumb....bolted it all together, PERFECT!

and the FINISHED PRODUCT!

If you came here looking for information about how to "wire" your Taurus fan, using a controller circuit or something similar... please checkout my Taurus Fan Install page to get the specifics of how you can wire this fan up in your Jeep, especially useful if you're trying to wire it up in a stock type 6-cylinder motor, and using a Hayden Imperial fan controller circuit.  

I plan on using the PCM with my new Chevy motor to actually decide when to turn on this fan... but I'm going to use it in conjunction with the imperial circuit relay system so that I have the ability to manually turn it off and force it on if I so choose.

On to step eight...
