Yeah, this is the age-old issue with Early Broncos. Just not enough room between the radiator and water pump snout for a decently powerful fan. And without power, you don't get good cooling in the poor aerodynamic environment under a Bronco hood either.
Result is overheating in many cases.
A pusher fan is not as efficient as a puller, but even to use a pusher you would need more room than a Bronco has between the grille and the core support.
All in all its just not a good place for an electric fan until you make more changes.
Some have gone to the point of cutting the core support and moving the radiator forward enough to fit the fan. But either moving the radiator forward or using a pusher fan means you lose your hood latch and have to go to hood pins instead. Which some, including me, would rather not do.
The most common solution so far is to convert the front accessory drive system on your engine to the '97 to '01 Ford Explorer V8 serpentine system. Doing so will net you almost an inch more room in the front. Then you can install a Ford Taurus V6, or Lincoln Mark VIII electric fan and most find this a happy medium.
Many of us have swapped over to the Explorer serp setup even without using an electric fan. Since the Xploder's mechanical fan is so good, it has not been an issue.
And speaking of an issue... Why is it that you are wanting to change your fan to electric? Reason I ask is not to tell you it's not a good option, because I like the idea of electric too. But to show you how much work you need to go through to get there and see if it's really worth the trouble to get what you want.
For most the results were less than stellar. But if you have an overheating issue already, it might not be the old fan unless it's been changed to some aftermarket setup. And if going electric you need the very powerful fans.
We sell some that have worked out well (
https://www.wildhorses4x4.com/category/Bronco_Cooling_Fans) but also the Taurus fan has worked well. But whatever fan you choose needs to put out some serious CFM before it's considered a good candidate to cool a Bronco.
There is a Jaguar fan clutch and some odd setup that has worked well for some here as well. There are discussions about it you can find if you google the subject and add "site: classicbroncos.com" to the search. OR something like that.
Good luck. And welcome to classic too!
You new to the Bronco world? Or have had it a long time now?
