Ed Klepeis,

Can you modify this one pass  Howe rad to a two pass for me?
The tough part is welding the partition between the tubes.

The in and out necks are 1-1/2 inch hose barbs.
The rad will be horizontally mounted under the engine so the barbs
should be all the way over to the right in each section
to simplify the water pump plumbing.

The front end needs a 30 degree chamfer on both ends to fit under the
cowl better.

I'll do a 3D for you in a day or so.

OK Ed here is the 3D I'll ship it out Second Day Air UPS tomorrow.

The rad will be horizontally mounted under the engine so the barbs
should be all the way over to the right in each section....

Made a mistake there. The hose barbs should be on the LEFT side from
the tractor pilots perspective. That is the side of the Mazda water pump
inlet and out let. 1-1/2 inch hose barbs.

This core is 15 by 24 by 2-1/4 for those that might be interested.
810 cubic inches. Just in case I need it for the turbo engine.
If this doesn't cool at 110 F ambient there is no justice :)

This is also the same core I used in the Dodge Caravan test rig and core air
flow
is about 40% of forward velocity using a simple Kays & London wedge shaped
duct.
Intake opening area was about 25% of core area or 15' wide by six
inches high. The stock Mazda oil cooler will be mounted along side
this core.

Paul, how about an air bleed  or drain petcock? Just to make sure you are
not forgetting it.
Bulent

Good point. I did forget it. Thanks Bulent. Can you had a small bung 
on the front end for air bleed. Ed? 

I did not get it shipped today. First thing tomorrow morning.
