Is there any truth about the over heating issues with the new Broncos?

I have t heard that one. What have you got for us on this topic?

It's on the Bronco Sport supposedly. Only one tester has mentioned it. It's posted under the Sport section on here

Talking about the Bronco Sport?

Not sure if it was this forum, or another, but it's in the owner's manual. I posted the text, I thought it was on this forum. The 4WD system can overheat, shut the a/c off and need a 10-minute cooling off period. Yes, the Bronco Sport (and other Ford 4WD (AWD) systems can overheat).

Go look at the owners manual.
It is posted on a thread here on Bronco Nation.
It explains this function of the vehicle.
if you read the owners manual
Will help understand the topic.
Know what you are buying and how it works!!!

My, my.

interesting following...

Indeed.

So thank you Gary for letting us know of that issue and thanks to the others for the information as to why. A few points of clarification. Either Gary was trolling and wanted to start something or he genuinely was new to Bronco, 4x4s and off-roading in general. I am guessing it was the latter. Some of us are brand new to all those things mentioned above and would have no idea to even think that was possible in today’s day and age. Some of us don’t work on cars and some of us don’t have time to read a manual before we even get our truck. Some of us are brand new to this and just need some assistance. I guess my point is if you have the knowledge be a mentor don’t be sanctimonious. Just my thoughts.

Yes, there is truth to it.
there is a drive around video of it happening on a sport model. I saw it in BN somewhere about a month ago.
But...
The overheating is a safety measure built into the vehicle to save damage to the drivetrain.
I would assume the larger Broncos will have the same programming, but higher abilities in the drivetrain, as it’s generally “more” off road worthy.

I recall seeing that video as well here on BN somewhere and it was a Bronco Sport Badlands. The driver was going heavy on trying to climb a slick rock trail and eventually got some kind of warning the drivetrain was over temp and he had to wait for a few minutes for it to cool down.

One reason to not get automatic tranny they pump heat into the radiator overheating tbe engine.You will never have this problem with a manual.

I don’t think the Bronco (not sport) will need this type of safety measure it has a totally different 4x4 than the sport. The sport uses clutches to engage the wheels for 4x4 it is closer to an AWD than 4x4. So heat is a big deal for their drive system the sport’s 4x4 will heat up more, and quicker than the 4x4 on its bigger brother. That said the Bronco will have parameters for the transmission and engine to keep them from overheating.

If the t-case is gear (not clutch)/chain driven, we're in luck (speaking big Bronco).

There is an overheating issue with the 2.7 bronco. One of the radiator hoses rests up against a pulley bolt and I'm assuming the heat melts the hose and leaks the fluid. Quick fix is to zie tie the hose out of the way. Sorry I don't have pictures.

Wow since the original thread was posted over a year ago regarding the Bronco Sport having the issue, I hadn’t seen anything about it. Never heard anything about hoses melting or any issue like that. If you could direct me as to where I can look up this hose issue I would like to check it out. Thanks!

Yeah i dunno how i ran into this thread, but its good info.
I found this

Thanks! Taking a dive into it now(y)

I bet they forgot to put one on at the factory. Now I have to try and remember to inspect for this, when ever I actually get my Bronco.

If I recall correctly the 2.7 coolant hose was touching the pulley and the friction from both touching rubbed a hole in the hose. Causing a big mess and engine failure. Not caused by heat.

Yes, most 2.7 owners in that batch of broncos zip tied the hose and problem solved (or better yet problem avoided).

Not heard of any big broncos overheating since taking delivery of our 2.3 MT 9 months ago. But I do recall a thread on B6G last year where a number of 2.7 engines failed because of fluid leak via hose touching pulley. Then the valve dropping issues started and we never really heard about the hose/pulley problem ever again. Until now..
