4k tow package Drive ratio, cooling and radiator fan percent difference recource/discussion

[RaptorO7]

It’s a 2025 XLT I’m looking at. But that would be good enough I hope.

im assuming ur Mav is an ecoboost from ur account flair you will be gettting 238hp
Also here is the graph for the 2025s

ur Mav should be the 8,130 one
Check the driver side door jam when you get it, it will give u ur towing specs.
Then subtract the 4000 tow capacity and the maverick dry weight and that will give you how much weight you have left for fuel, people and cargo.

Down graded HP and torque nubers wont happen till after June or so if they do. 2025 eco's have 250 hp now

Tim from Long Mc arthur ford in Kansas has videos on here about it.

You can find his videos under Ford video guy. He is very informative

Ok interesting did not know that

Tim said it might not even down grade per his connections at Ford. Ford was covering the bases in case it did for when it comes out

I see the 250hp / 238hp mentioned on a few other sitrd like Ford Authority:
https://fordauthority.com/2025/02/2025-ford-maverick-ecoboost-horsepower-rating-matches-2024-pickup/

"However, one particular detail that seemed rather strange was the fact that 2025 Ford Maverick pickups equipped with the turbocharged 2.0L I-4 EcoBoost engine actually lost a bit of power – 12 horsepower, down to 238 versus 250 for the outgoing model. As Ford Authority previously reported, this drop was due to the addition of a gas particular filter, but now, it seems as if the automaker has managed to make up for its impact on output.

According to CarBuzz, 2025 Ford Maverick EcoBoost models will indeed offer up 250 horsepower, as was the case with the outgoing model, a fact that Ford Truck Communications Manager Dawn McKenzie confirmed to Ford Authority. The reasoning behind this change is unclear at the moment, but as Ford Authority previously reported, the addition of the gas particular filter is designed to help reduce emissions, and according to CarBuzz, the previous 238 horsepower rating was merely “a clerical difference relating to California emissions.”

The Hybrid or Ecoboost will tow what you want just fine.

Base your engine on the PRIMARY purpose.

Primarily a commuter vehicle? Hybrid is the clear winner.

Tow most of your miles out of the year?
Go with Ecoboost.

@GeorgeG4

I have a 1500 lb side by side OHV in this 1500 lb trailer, add in a couple of spare tires and accessories and I'm 3200 lbs all in.

I have electric brakes and an after market brake controller in my HYBRID.

Wind resistance is a killer to gas milage. But with a parachute like this, I hardly need to brake at highway speeds. I don't exceed 65 MPH.

Nets 18-20 MPG depending on conditions.

The heavy weight is most apparent at slow speeds because regen is less and engine brake is less at lower speeds so trailer brake is essential.

Barely made it under this bridge in a park.

Yeah, the vehicle I’m looking at is the Eco boost version all-wheel-drive with the 4K tow package. My trailer is open galvanized steel 14 foot long with a with a spare tire mounted to it. my Can-Am weighs 1700 pounds. I don’t know how much the trailer weighs.
It sounds like it won’t have any issues handling it. I know when I tow with my current vehicle the Jeep Cherokee Trailhawk I swear I could just watch the gas gauge continuously drop.

Oh, one more thing all mavericks have tow mode which basically keeps the revs higher and downshifts to higher rpms when ur braking.

Ok so the 4k tow offers 3.81:1 rather than the standard 3.61:1.
But the difference is less than 5 percent (4.96)

here is the difference between the the radiator capacity. Here
8.2 vs 8.72. Or 8.7 vs 9.2 fully filled
This is around 6.34%

both have transmission oil coolers.
Even though ford specifies 4k’s get one doesnt mean 2k’s don't.
I think non 4k cooler Here
And i think 4k cooler Here

The reason I'm saying “i think” is because there are 4 on fords parts list a 1.5L a 2.0L another 2.0L for the tremor pack and an unspecified liter amount automatic transmission one. Some say hot weather and normal weather climate maybe they outift different mavericks depending on where they are going to be sent to. Depending on the climate. Also, maybe the 1.5L is only used in the hybrids since the eCVT doesn't need as much cooling as the 8f35 trans. I also could be wrong, the hybrid might not even have a trans cooler at all since all of them say automatic, which doesn't mean ford wouldn't put and auto cooler on a cvt.

The 2.0 liter says for class two trailer towing in the specifications
So im going to speculate mavericks in hot climates get the 4k tow package one even if they have a 2k tow truck.

So ur getting 25% bigger trans oil radiator in a 4k in the normal climate.

(Edit) the liter amount may just mean what engine its for since the 2.0 eco can use a 1.5 eco rated trans cooler and still stay cool.

Now the other difference is the radiator fan. It seems like the tremor might have 2 smaller fans.
Here are the two packages of them

Tremor Here. The tremor one 25in in Length meaning “I think” there is two of them.
IF ANY ONE HERE HAS tremor PACK TAKE A PICTURE OF THE radiator FANS. I would like to make sure that im correct.

(Edit this is fx4 and 4K) Here 43in long assembly
(Edit this is just 2k ) Here 33in long assembly


i dont know how much more cooling there is in two 25 in fan assemblys vs one 45in assembly but if anyone wants to have at it they can try. For fx4 vs tremor.

The difference between 4k and 2k is 45in vs 33in

Anyway. I think the biggest reason why standard non 4k have such a low tow rating is because they don't have a trailer brake controller. They only have the 4-pin instead of the 7-pin. Im not saying to void ur warranty by towing 4k pounds with a 2k truck just because you added a brake controller. But i think it should get a few extra hundred pounds safely. Not 4k but i would say around 2200-2600 being conservative.


Ok, this was my summary of this 4k vs non 4k issue that many people wanted answers to. If you have any conflicting evidence please post.

EDIT: After looking at little more at the ford parts website ive concluded the oil trans cooler on the 2k does not run to a radiator while the 4k does. The 2k cooler is larger and most likely gets its cooling from a scoop under the skid plates or it runs to a small radiator somewhere since i cant see the diagram on the 1.5, while the 4k is smaller it runs to a larger radiator in the front of the truck.

You can't simply compare the percentage difference between stock and 4K to arrive at your conclusion. I guess the easiest way to explain this is the rear end. It may only be 5% but plot it on the torque curve at highway speed and I'll bet it's better than 5%. As for cooling the trans and motor, well that's more for limits. On a 70' day, flat ground. you're probably okay but at 105' uphill you might regret it. My guess is there is about 10% fudge factor on factory limits, maybe even 15% but when you're 20%-25% over you're taking a risk that I wouldn't chance. I suspect the reason for your post is that you want someone to give you a majority over that voice in the back of your mind.

Nope just a resource to help others see what the difference is between 4k and non 4k vehicles since i couldn't really find a good one. I also find it very hard to believe the maverick has the same tow rating to a 2.0 FWD Ford fusion.
I do agree that percentages should not be used as a comparative tool for everything but I think drive axles will work for comparative percentages. I am going to edit my post about the 25 percent more cooling because I think that is wrong anyways.

Im just speculating that ford is being very conservative with their tow ratings with very extreme conditions and a few modifications such as a trailer brake controller should bump that rating up a few hundred pounds.

(edit: it has been in the back of my head and I'm expressing my evidence of why im feeling this way. Im not looking for validation or belittling the 4k tow package. In no way am i telling people that towing 4000 or even 3000lbs is safe or good for ur car. But i firmly believe 2000 is not the Maximum safe tow ratings for these trucks.)

 

[The Real Maverick]

I've said it before but seems a good place to say it again...

Tow ratings are for comparison purposes just like MPG on window stickers are.

There are no absolute values here.

In the 2k Maverick you CAN tow 5,000 lbs at 25 mph.

In the 4k Maverick you CAN'T tow 5,000 lbs at 95 mph.

(without breaking stuff or killing yourself)

Tow "ratings" are a voluntary, not mandated by any agency, self reporting "curtesy" to the shopper/buyer.

Thousands of vehicles come with no tow rating at all, but do just fine towing reasonable loads.
