Ideas for attaching electric fan shroud?

[JustJohn]

This has been sitting a while and it's time to resolve it. I wasn't happy with what I previously had and was wondering what others thoughts would be.



You can see the flanges I have available and where it sits. I was thinking about a couple of strips welded to the radiator with studs but that would push the shroud a little further out and I'd need to figure out seals...

I could also just have it welded directly to the radiator. Not sure how I feel about that for the long term.

My .02 is that I would weld brackets to the shroud that go down to the radiator and match the radiator mounting holes so you can use the same bolts to hold the shroud and the radiator to the core support.
Brackets would be kind of "Z" shaped.

That is actually what I had previously. The current pictures are just after I took everything apart. What I didn't like about it was that it was a pain in the *ss to install and remove the radiator at the same time.

I stared at it for a while last night and think maybe I'm going with the idea of having a couple of pieces of bar stock welded to the rear facing flats and using studs/acorn nuts to hold it on. It's the cleanest thing I've thought of so far.

I'm using a Cold Case BB radiator and I designed my own fan shroud. The CC has a hollow upside down "U" channel across the top and bottom, so when I designed the shroud, I extended the top section forward to cover that channel and then added a small 3/8" return. So the shroud sorta hooks on over the top of the radiator and it locates the shroud exactly where it needs to be. To ensure it doesn't move, I added a couple of rivnuts to the channel and I have nice finished threaded screws/washers up top. On the bottom, I simply added two straps and again used rivnuts to locate the straps. In the picture below you can see the top & return.



In the next shot you see it all mounted up top.



So to remove the entire shroud with fans attached, I go below and remove two (2) screws from the straps, then remove the two (2) top screws. Once I disconnect the power plugs to the fans, I simply lift the entire assembly up and tilt (yeah its tight in there) and it comes out and the radiator is still mounted.-Mike

Here's what I ended up doing. Happy with the result short of an entirely new shroud.

John… How’s the dual Spal fans and shroud working out?
