Electric Radiator Fan Shroud

[TOOLEAN]

Hello all, I would like to trim the large stock fan shroud and mount the fan directly onto the back of the radiator.  I want to do this because I need space for a waterfall hood (aka radiator extraction duct).

Has anyone trimmed their stock fan and mounted it on the back of the radiator?

Thanks, Nate

I guess it is two pieces not one...

And I will probably try to secure using something simple like this...

I think you're on the right track. I trimmed the shroud for my E30 by using a cordless circular saw with the blade on backwards. I intend to install a Volvo fan, but I'll use metal brackets. Nothing wrong with the plastic tie rods you linked to as far as I know.

The problem I am running into now is that the stock electric fan does not have a flat face to mount against the back of the radiator, it's got a large boss for the fan motor.  I will keep working on this and try to get some pictures up....

The fan blades require space in front to quietly and effectively move air. By flush mounting its only going to cool the center of the radiator and run much longer.

You need to fabricate a slim (3/4 to 1 inch deep) aluminum shroud to mount the fan, any machine shop should be able to do this if you give them the measurements. I can't find the link but a few companies build this for e36.
