Thanks Carl. The radiator is built by US Radiator, sold by Rick's (and others). I picked for that reason. I had thought they had a pretty good reputation.
The radiator looked good, mounted perfectly (so I thought). It was just too close to the fan clutch.
The fan blades are almost 1/2 way in the shroud on the bottom and 1/4 inside on the top.
I had drilled another hole on the shroud to pull it closer to the radiator on top. After I moved the radiator closer to the support, there was ~3/8" gap on top. The radiator is also 1/2" closer to the pass side to center it in the support opening to get it flush. This twisted the shroud a bit using the stock hole. Didn't like the look of that.
Now that I've measured top and bottom, I guess I pulled the top of the shroud in too close. I can move it back a bit and live with the gap if that will make the fan work better.
My "adjustment" is probably not mounting the radiator perfectly parallel with the support either. Looks even tho'.
Didn't think this would such a pain! Replacement radiators should be just that!
At least it will be running soon!
I also mounted the external tranny cooler on brackets in front of the radiator rather than use the ties through the new core. Don't know how thick the tubes really are and didn't want to risk wearing a hole in one.
Thanks again. This is a great place!
