How's the aluminum rad holding out?

Is it a Behr or ?

Last spring when I replaced my radiator in my 83 diesel, I went with the newer Alum. It seemed very strong, and looked just like the original at 30% the weight. Aluminum has a much better heat transfer coefficient than any of the yellow metals to. > Anyways when I pulled the radiator, I took out the fan shroud to clean, inspect, and repaint. Looking at this fan I just though technology has come along way with these electric fans since 83. So I started to do some research. > I seems there were two fan types. The 83-85 all used the 2 speed fan. The low speed ran about 200 watts or 16.6 amps. The high speed is around 300 watts or 25 amps. The other fan went into any 86 and later with A/C, this was a switched 3 speed that draws 450 watts or 37 AMPS! > After researching the new fans. I decided on a 12" Diameter, 10 blade pancake style that pulls 1650 Cfm and draws only 7.5 Amps or around 90 watts. Then I cut off the 3 supports that held the old fan on leaving and perfect mounting area. After a little trimming and 4 -1/4" S.S. bolts my fan was mounted. This fan tucks perfectly under the shroud tunnel. > The next step was controlling the fan. I went with a adjustable fan control kit. This uses a sending unit that is a radiator probe, that just gets pushed into the fins in the middle and around 4" down. This has a control box that I mounted inside behind the glove box for easy access. The control knob adjusts to turn the fan on any where between (170 - 210 F) This way you can change settings from summer and winter. The control unit also comes with and override switch. I always use these so if you are pulling a big hill you can flick on the fan and get ahead of the curve. > The other advantages are that is much more quiet, weighs less, pulls more air, as the blades span the whole shroud opening. Plus it uses about 30% of juice than a stock fan!
