electric fan install any tips/ideas to get my setup mounted to the radiator?

[JeffP1167]

it is a GM aluminum/plastic tank radiator that I want to mount 97 camaro LT1 fans to.

I have it all electrically setup to use two GM weatherpack relays and thermostatically controlled for 228on 204 off. This will going into my 82 vette.

One idea I have is to bend some small 90degree tabs and pop rivet them to the upper and lower core rails and then pass s crew through the shroud into the tabs. woul this area of the core be strong enough to hold the fan assembly?

Lets hear some of your ideas.

I have that exact fan shroud. I wouldn't use the core to support the fans. There are 4 lugs on the sides of the fan shroud (2 on each side). Try to attach to them, preferably into the radiator support.

In another thread I described how I did my Spals....tied into the rear tabs of the U shape core supports with angle aluminum going laterally side/side top and bottom, bolt the shroud to that support, never touches the radiator, I be super scared for that thin aluminum and plastic tank rim to support a flea, let alone those fans.....

How about this, you can see in this picture my original upper radiator retainers, they have a place to bolt what I think was originally the fan shroud.



What about say brackets that attach at these points on the shroud or a flat piece that runs across the shroud and ties to both upper mounts?

Then any space between the the radiator and shroud could be sealed with lowes foam weatherstripping

Jeff, I still think it's easier to just catch the plastic shroud at several points with washers to back up the bolt head/nutz....it seems like they counted on the shroud to support the fan weight, from appearances I can see, sort of like evenly distributing the load/flex for road vibrations....you concept maybe work well too, I just dunno from pix....
All I know is my fans been there for maybe 6? years now, and they fine....

Because the radiator doesn't have the catches for those tabs

OK, I forget about later sharks...over the years...worked on many of them, but can't keep the players straight without a score card....

I know my '72 had some fairly heavy steel U's to catch the rubber mounting, and the rad floated top and bottom on them, putting a hole was easy, adding the struts for the fans....

on your setup, it maybe not work so good, I dunno,.....thought it was the same as mine....

I know on my V6 97 camaro the fans are mounted with the tabs. I'm wondering if a LT1 radiator will fit in my 82 vette.

Here are brass replacement core size. I put the camaro radiator sizes due to that is what these fans came from. I suppose I could move the lower radiator cushions in a bit and mod the upper mounts. However the upper radiator hose is mounted much lower on the tank then what this vans radiator is.
