color=#0000ff size=2>I have a 1,150 CFM fan behind my radiator and it's located
near the top of the radiator. I chose that position because the
temperature gradient is greater at the top, due to the hot water entering from
the top. With a greater temperature differential, more heat is shed from
the radiator with every CFM that passes through the
radiator.</FONT></SPAN></DIV>

color=#0000ff size=2>Mounting - I brazed studs to the outside of the
radiator. I also brazed a coupling on the front of the radiator, just
above the top of the core, for a modern OEM style fan speed switch to
control the fan. I put it on the front of the radiator, so it would not be
seen. It's easy to change it through the grill
opening.</FONT></SPAN></DIV>

<DIV>Am rebuilding a 55 TR2 and will be installing a Flex a Lite 1050 cfm, 9 amp
load, 10 blade, 12" diam. electric fan with variable speed control kit and
manual on/off switch on an aluminum radiator without crank hole. Radiator
effective area is 11 1/2" wide x 18" high x 2 1/2" deep. Stock Tr2-3b
radiators were about 17" x12" x3" and the crank hole was up from the bottom of
the fins about 6 1/2" and the stock fan appears to span the entire width of
the stock radiator, some 13" diameter, so it is pulling air into the bottom
2/3's of the radiator. The grill opening on the 2 starts just under the
crank hole and has an opening at the radiator face of about 11" high and
averages 13" in width. It appears as if the fan is pulling half
its air from under the front apron lower skirt (the 6 1/2" below the crank
hole) and the other half from the lower portion of the grill opening. It
then seems that the "ram" effect of air being forced thru the upper 70% of the
radiator when under way completes the cooling tasks.</DIV>
<DIV> </DIV>
<DIV>Given that the fan I will be using is slim enough to be positioned at any
height behind the radiator (puller) without interference from the cross brace
connecting the spring towers, where would you think would be the most desirable
location to install the fan.<BR> </DIV>Planning & Development
