cooling fans

[dukdogz]

I want to get rid of my mechanical fan on the motor, hoping someone can give me some insight on what electric fan set up to use junk yard or new. Normal 75' bronc 302, factory radiator. There is just no room between the pulley and radiator and I do not want to cut the thing up to make stuff fit unless I have to.

Curious..., what precipitated this change..? What exactly needs cutting...if it's stock..? Is there an overheating issue..?

Is the shroud in place.? Are the rad. brackets properly placed..?

I believe there's pusher electric fans that mount on the front of the rad. available, if you prefer elect. Orange Crush went thru all of this a while back ... give him an email/pers. message. (PM)

Also, some waterpumps have to long a nose... :^o is this your situation..?

mechanical fans don't work so well in deep water/mud, I was not aware of a shorter nosed water pump that may be the ticket. never had an overheat issue, has a fan shroud and the radiator is all factory works great but i am looking to "waterproof" a little more and free up a little more power. I have not found a pusher, or puller that moves enough cfm to keep things cool unless I want to start hacking up the core support. to make things fit. I know someone out there has to have done it though.

We had a fairly long discussion of this recently, take a look at this, read through the whole thing http://broncozone.com/forums/index.php?sho...ncoln+Mark+VIII

Good luck,

I see., check SummitRacing.com they have a pretty good selection. B)

They also have electric/hi-flow water pumps that might work for you..

Listen to SeaBronc. We just went thru all this so the thread is fresh. If you're having probs due to deepwater be advised that electric fans do even worse, at least the mechanical/clutch fans keep going, water of almost any depth stops electric fans dead in their tracks. I've seen guys have problems after a long clims and a reasonably short ford across mid-to-high water that stopped their fans but didn't quite reach high enuf to cool the radiators itself (full-size, not EB). Clutch fans actually work well in this situation because they stop with the high-water (the clutch) but keep cooling whenever it drops and the spray cools the radiator. The electric fans just don't have the juice to spin thru the water and they just plain stop. A strictly mechanical fan w/no clutch and a flex-fan worked well foe me in this situation, sprayed a lot of water under the hood but it worked and never failed. There are a lot of fan choices to be made depending on just what you plan to DO with the truck.

Some of them can actually be dammaged by water. That is why they have to be shut off when fording deep water.

Good luck,

the idea is to also wire in a switch to shut the fans off

works great on my buddies 75 but he put a 5.3 chevy

in his and set the motor further back

I think if you read the post I gave you a link to you will see that we agree. My last post was to Broncobill. As you can see from my signature, I'm all for electric fans. Just get a good one.

You also need control in the cab to force it on if for some reason your sensor fails and if you are doing any off road driving, then you need to be able to turn it off when going through water that may come up to the fan level. That can be accomplished by installing an ON/OFF/ON switch in the cab.

Good luck,
