Radiator fan debacle....

[DirtDonk]

Mine does the same, the thing just can't breath trapped in a sardine can at idle or stop n go.

used to be very common to see Broncos crawling around on the trails in summer, with their hoods completely removed and stowed on the roof or roll bar.
Letting the hot air out from under the hood was a sure-fire cure almost every time.

I have sat and contemplated venting the hood scoop or installing some of those inter front fender screens...

Regarding the hood scoop, it's a visually appealing or functionality decision!

Absolutely. Doesn't hurt that it makes the truck go faster either!
See? Go-fast goodies aren't only for the young and restless muscle car owners!

In-between those are hood louvers too. I'll have to find out what happened to ours, since I don't see them on the site anymore. Supply chain, or lack of demand maybe.
In a further self-promoting vein though... The Ventilator side skirts (https://www.wildhorses4x4.com/product/Ventilators_Inner_Fender_Vents/early_bronco_vents_ducts) really do help most of the time. As do the air-dam / tool-shelf products (https://www.wildhorses4x4.com/product/Stainless-Air-Dam-with-Built-in-Tool-Tray/Bronco_Radiators) that focus more incoming air through the radiator instead of around it.
I say 'most of the time" because some overheating or running hot issues are not related to air flow. Some are coolant flow, and many in the case of older vehicles are related to overall engine tuning and condition.

One other thing that "might" have a little effect on air flow out of the engine compartment, especially when used in conjunction with the Ventilators, would be the fender mud guards (https://www.wildhorses4x4.com/product/Stainless-Steel-Fender-Bodyguards/newproducts-EB). They're not for cooling, but mostly for keeping debris out of the pocket between the outer fender and the kick panel. But I figure anything that reduces turbulence and smooths the airflow transition around that pocket and out of the fender can't hurt!
So maybe not a cure in and of itself, but if an air flow issue is borderline fixed, this might be the thing that puts it over the top.
Just a guess...

Some of that is on my hit list!

Have to get the new 23 gal tank installed, so I can run more than 100 miles with out searching for a gas station.... Lol

For sure. I like getting over 250 miles before thinking about re-filling. I actually slate the stops for about 225 just in case, but tend lately to push it further than I should.
I've been pushing my limits a few times and the engine actually coughed and stalled out momentarily while the pump was hunting for something to suck up.
Not a dire situation, since it fired right back up and I have stations on practically every block where I spend most of my time. But definitely lets you know in no uncertain terms when you're about to go dry!

Gotta' get out of my old habit of not caring since I always had a second tank to switch to if I ran out in one. With just one, like most other vehicles it's important to keep an eye on the falling needle or mileage.
My small pickup has a single 28gal tank I think, and my big pickup has two with a total of 49 from the factory. When the new tank goes in the rear position, that will go up to 80 gallons!
If I run those dry, I'm the only one to blame. And will be in the poor house for re-filling as well!
