Hi guys i finally got my eletric fan all hooked up and running the cause of it not working was the ground hand to much paint on the car so i scraped it off now it works like a charm.

Qustion how did all of you mount your eletric fan? :shrug:




:hail2: :hail2: To all the people that helped me the las two days.
 
Not sure what type of fan you are running but I just drilled some holes in the top of my SN-95 fan and bolted it to the radiator on top and went to the auto parts store and bought some electric fan straps, (the ones that go through the radiator), for the bottom.
 
They come in a red box at autozone and are called radiator pull thru straps or something.. they look like tie straps but are black usually and have a circular end. If your fan has existing holes, just pull them through, or drill some new holes and use them.
 
Here is how I mounted mine.

Those pull-through ties were made for securing something lightweight, such as an anxiliary cooler, to your radiator. Do NOT secure something as heavy as an electric fan to your radiator. The weight, plus the start-up torque of the heavy fan puts a lot of force on those ties -- and in turn stresses the radiator capillary tubes. This will lead to stress on your radiator, and eventually your radiator will start leaking.

Support the weight of your radiator with something that mounts to the tabs at the bottom and to the slotted part across the top (like the stock fan shroud). That is the only reliable, safe way to do it.

I'm going to disagree with you. My Taurus fan weighs about 5 pounds if that, and with the DCC unit doesn't start up suddenly and torque around. Those pull through straps are plenty to hold something like a fan on. They are standard issue on transmission coolers/oil coolers, and they weigh just as much if not more when filled with liquid, as an electric fan.
 
Disagree if you want. But there's no 100% guarantee that those nylon straps will properly support the fan w/o damaging the radiator.

I toasted a brand new radiator using those damn nylon ties to secure a taurus fan.. One of the nylon ties pushed down on the tubes until it split. I surely will never use that method to secure an electric fan.

It's up to the original poster if he wants to take the chance...
 
I dont recommend the nylon ties that go throught the radiator, I punched a hole in a rad tube once with them. I have always found it easy to use 3 or 4 flat metal straps or similar items to make fan and cooler mounts.

My current e fan in the 82 is mounted with 3 wire ties, and has worked for a year. I did put a small rubber pad left over from somewhere, to keep it from rubbing the fins. I was going for easy to remove and service, and min weight.
 
While those straps pass through the radiator, all the ones I've seen have pads on both ends that are designed so that the load is distributed on the fins -- the strap itself isn't supposed to be hanging on the fin-tube.

Nevertheless - I agree 100% with biggeley. You'd have a better design if the load of the fan were placed into the frame of the radiator - not the fin-tube coil.

That's how I mounted mine - 6 aluminum tabs (3 top, 3 bottom) that secure the shroud to the frame of the radiator. So the fin tube coil is unstressed by the fan/shroud assembly. Picture at the link....

I mounted my fan on the top with bolts that screw right into the top of the radiator, using the same bolts and tabs that held the factory fan shroud on.

Then at the bottom I used the pull through straps to hold the bottom of the fan to the radiator. There was no stress on the tubes as the top bolts held the weight of the fan, the bottom straps were just there to hold the fan from blowing away from the radiator.
I had it like that for 5 years and never had a problem, but the bracket idea from the bottom sounds even better.
 
dang

I already mounted the fan but i was extra carfull when putting the straps truoght the rad. I hope it causes no probs ill look into that sheet metal i was thinking of somthing like that but ill do it to my new rad ill eventually get a aluminam rad. :banana: :banana: :banana:
