Electric fan mounting

Hello everyone. I have what is basically a Ron Davis 1-50MU6566T radiator with the outlet on the opposite side for a 5.0 conversion. I'm trying to mount this fan on it and am limited on space.

https://www.amazon.com/dp/B000FKBR6G..._yuNcDbB2N0J34

Because I'm so limited, Id like to mount it through the radiator with these.

I just talked to Ron Davis and he said people do it but he doesn't recommend it. Anyone ever do this with an aluminum radiator? It was expensive so I'd rather not destroy it, but to mount it any other way I'd have to cut and modify my core support.

What year Mustang? Why is so tight? Are you also running a engine-driven fan?

You could always get an electric fan that acts as a pusher for the front of the radiator. They aren't as efficient, but the right one can be enough.

I've used those straps on a copper radiator before, the trick is to make sure they stay tight. The same would apply for the aluminum one. If the fan loosens up and starts moving a bit, that's when it'll get ugly, but shouldn't fundamentally hurt anything but the look of the cooling fins around the straps.

Its a 66. Electric fan only. I have 3" between the radiator core and the snout on the water pump.

Can you run a shorter water pump? Mount the fan, with brackets to the radiator support? Either way, I wouldn't hesitate to run those straps... if you're concerned, just keep an eye on them for the first few weeks...

I ran a 16" electric fan mounted with that type of strap for about 5 years and never had an issue. I'm not saying it's the best way, but it didn't cause any problems. In fact, the straps outlasted the fan motor. I'm still using the same radiator BTW.

Well, I tried. Going to have to try something else. May try to shave down the water pump nub and get some lower profile bolts. Really don't feel like going though the pita of moving the engine back for less than 1/4"...

You know you can mount the fan on the front of the radiator and just wire it backwards to blow.

Looks like there's some room to modify the radiator support and move the radiator forward a bit.

There is even less room in the front.

There is a bunch of room for that. The first thing I'm going to do is trim the edges of the shroud so the fan fits completely flush on the radiator. If that's not enough I will either grind down the nub on the WP or move the flange on the radiator.

I had a car where I used those mounts years ago- through vibration it eventually wore a pinhole in one of the radiator tubes. I'd never do that, unless it was an emergency.

What kind of fan? I used this in my build- its only 2.05" thick and worked for me. I had similar room.

This company also sells a thin pre-made mounting solution that worked for my car.

I didnít want to use those either (read a few stories of holes in rads) so I made some simple brackets out of 1Ē aluminum stock. I bolted the fan to the bracket and then ran the rad mounting bolt through the other end of the bracket when I bolted in the rad.
