Anyone know if it's a straight forward swap from the standard 2018 Radiator to the Heavy Duty 2018 Radiator?

Should be just a strait forward swap.
When you have the HD radiator beside the regular radiator can you snap some pics and note the differences between the two?
Some people on here don't believe that there is a HD radiator for the 3.5 ecoboost.
Even though there is separate Ford part #'s.

Following.. would like to add additional tow capability. 3.31 gears is the only other reason not to tow the 9k, but I'm sure this truck would handle 7500 pounds no problem with a radiator upgrade. With a 10 speed transmission why would the rear axle matter that much? You can lock out the top gears.. The top three gears are overdrive anyway!

I think there is some question whether or not the HD Tow Pack gets you a transmission cooler or not, not whether it includes an upgraded radiator. I’ve seen debate about the tranny cooler on here, but I don’t remember seeing anyone claim the radiator is the same in both configurations. I it’s 100% possible I missed it, however.
Previous gens had a separate tranny cooler with the Hd Tow Pack but the 4th gens don’t list that as an upgrade...hence the confusion.

Mechanical advantage is the term, Google it. It's like telling you to extend your arms out as far as you can and see if you can lift 200lbs, then bring your arms by your side and lift that same 200Lbs.
The transmission uses the radiator coolant to cool and heat the oil. Only the Raptor gets an external oil cooler(as of 2020). Increasing the radiator efficiency also increases the transmissions cooling ability. So when they say the HD tow gets a heavy duty radiator it is helping transmission temps as well.

Lots of conversation regarding this subject on the 3rd gen forum...There is a dubious part # for a HD Ecoboost radiator, but NOBODY has provided actual measurement/fin count, ect. to prove it exists...But, there are many actual towing experiences (including me) that show the "EXPY Ecoboost) is a "towing beast". For personal example. I have towed my 7,000 pound trailer for 16 trips since early 2020, the longest at 6,000+ miles, with absolutely no problem with overheating, even in Texas/Arizona summer heat. Just keep the tow/haul activated and go! PS: As noted, make sure you have the auxiliary trans cooler and an WD and anti-sway hitch!...

Since I have a 3rd gen, I just made the assumption that the 4th was the same setup...My XLT, non HD trailer package did not have the auxiliary trans cooler, which I added, do the higher trims also not have the cooler (which they did in 2015)?...Thanks for the updated info!...
Yeah doesn't matter what trim or HD tow or not on the 4th gen. No aux trans cooler. Why people want to swap to the HD radiator to get more efficient cooling since it is what also cools the trans fluid on the 4th gen. All trims, etc...have a heat exchanger for the trans.

According to parts.Ford.com, the components below are different with the heavy duty radiator. I am by no means implying that this is a complete list of parts that are different.
Radiator 8005
Seal 8348
Fan 8C607
Air deflector 8311
Radiator 8005
Seal 8348
Fan 8C607
Air deflector 8311
So has anyone actually performed this swap?

All parts are same except for the radiator itself... if I had a non HD tow I would give it a shot

At a minimum what I listed in my previous post is different. Seal, electric fan, and air deflector. What the actual differences are, I do not know, but they do have unique part numbers.

Well I could be wrong... was going by the parts list on the Levitt ford site.

Just noticed that the wiring diagram shows that there is a brushless and brushed version of the fan motors. I think the brushed 2 speed fans are used on the standard version. You can tell because they have a 2 pin connector at the fan. I have HD tow and my fans have 4 pin connectors, therefore I'm assuming the HD tow gets the variable speed radiator fans. If somebody tries to change fans it may require re-wiring and PCM programming.
I also noticed a charge air cooler cooling fan in the wiring diagram. Mine does not have a fan on the intercooler. When I searched on parts.ford.com, I couldn't find a fan, but I did find a wiring harness (Part number 8C290) that has "Charged Air Cooler With Fan" for the Navigators. Do the Navigators have intercooler fans?

I know the raptors have fans on the intercooler... not sure about Navi
