Maintenance Schedule

I’m sure this has been covered, but what are the general guidelines for maintenance schedules?

Currently at 25k miles on my 23 Badlands, mostly short trips around town, and moderate off-roading several times per year

I’ve been getting oil changes/tire rotations at Pepboys every 5k, replaced engine/cabin filters around 15k

Is there anything specific to do/check for at 30k beyond what Pepboys typically checks for? Should I go a dealership for certain intervals?

I think you're good. I'm doing the trans flush, diffs, and transfer case at 50k personally. How's your alignment so far?

I did get an alignment around 15k because of new wheels, tires, and level kit, so think I’m good for a while

Im in the camp you dont need an alignment unless you need an alignment its not maintenance its if you do suspension mods or knock it out from a big hit or something.

I am gonna check my fluids at 30k which I should hit before the end of summer I think and ill post what the fluids looked like and what I did, but I do tow a small trailer which puts more strain on stuff than if you dont tow and im in phoenix where its really hot and dusty but i never trust the ford schedules. 5k oil changes at least, and definitely 50k on Trans with filter, transfer case both diffs and I'll look at coolant but its usually 100k thing for me with plugs but ive never towed before.

Yeah, I'm doing earlier fluid & filter changes, but here's link to Ford's '23 Bronco 'Normal Scheduled Maintenance':

Keep up that schedule, that is perfect for it. For transmission fluid, coolant, and brake fluid, I would recommend going to the dealer, (Ford tech of 13 years here), mainly so that they will use the proper fluids for your vehicle and do the proper checks for fluid levels. The brake flush especially, with the Electronic brake boosters, if you don't bleed/flush them properly, it can set multiple warning lights and make your brake pedal feel off.

As for interval on all those, I recommend trans at around 60k, and if you get close to 100k without getting it done, don't touch it, coolant says 100k to 150k, but I prefer every 60 to 80k for my personal vehicles, and for brakes, have the fluid changed either once every 2 or 3 years, or whenever brake pads are changed.

for coolant check it sooner my buddys baby badlands is at 46k and I was helping him and noticed the coolant had turned a dark marsh green so I did a millivolt test and it was bad and he doesnt do anything hard on the car and really he baby's it and this seems to be on multiple engines and ford vehicles. I
still wanna do a ph test but just from the color he's getting a flush.

if you aren't doing the service yourself I'd say find a good place no quicklubs but ive had dealers do bad stuff so a dealership is not a guarantee. You can easily do all this yourself though.

ive never had an e booster but ive never changed brake fluid before 100k and always been fine even on newer 2020 and later cars in our family.

sorry, I misread your comment on the electric break booster. Yes, he is absolutely right.If you do a flush on those, they have to be done right?Because the way the valves work, you actually have to run basically computer program to flush it as I understand it with the different valves running everything. I'm actually glad that I don't have to worry about that

I wouldn’t wait very long to do the front and rear differential and transfer case. I did mine very early and found them all to be under filled from the factory. And then of course my 2.7 drained out 7.25 quarts…

I drive normal commuting with an offroad weekend about once a year. No towing (yet). So with that said, I change the oil every 5,000 miles. I also do all the air filters myself. For oil changes, I always have it done at a Ford dealership. My 45,000 is coming soon so I'm going to get a brake flush as well.

What about this interval for spark plugs? 100 000 miles? Isn't this too much for modern, high power engine with turbo chargers? Do they last this long in real life? For our european engines usually recommend 40000 to 60000 km. (25k - 37 k miles). On my Opel Astra it is given spark plugs change on every second oil change. :)

I usually get my oil changes done every 5k at Valvoline along with tire rotation. They do me good there, I just bought a 2026 Big Bend so with the new Bronco purchase/Ford pass you automatically get your first 4 oil changes free at the dealership. Not sure what the price difference would be between Valvoline and the dealership but makes sense to go to the dealership I would think since they know the car already.

I will be doing the transmission, transfer case, and front differential. At 60k-ish. I already have the fluid, new transmission filter and the deep dish PPE transmission pan. Just need a day to do the work. I did the rear differential last year when I changed out the diff cover.

And spark plugs I have a motor with 367,000 miles on it with the original spark plugs in it. I just wanted to see how long it would go without doing any maintenance other than oil changes twice a year. Maybe I should think about spark plugs for Darryl though.

High compression, turbocharged engines tend to have misfires when plugs are not quite o'k. Also ignition coils are suffering. Don't know exactly if 2.7 is one of them, but still... 100k seems much to me. Maybe 60k will be my choice

Yeah. Plugs are fairly cheap and fairly easy to change. I put in one step cooler plugs in my 2.7 because it has the Ford Performance Tune. Extra insurance against detonation.

It will be very interesting to me to see how do they look after these miles.

Hello All,

New to BN (in fact, this is my 1st post!). Recently bought a 2022 Bronco Black Diamond w/Squatch package, 2.7L V6, has 62,000 miles on it. Very clean, 1 previous owner. It had a fresh oil change done when I bought it, but will probably do another at 65,000, just to be safe. Air filter looks really clean (as does cabin air filter).
Was thinking of doing the spark plugs at the 65K oil change as well. Would you recommend the NGK IX Iridium plugs?
Anything else I should be looking at, maintenance wise?
Will be 98% in-town/daily driver, with occasional light trail/camping trips a couple times a year.
TIA!!

So I just changed my transmission fluid.And while it was not terrible, i'm glad I changed it at twenty nine thousand and I wish I would have changed it.Sooner.

the change of my oil and filter every five thousand and you can tell that it's just about starting to go bad.So I really wouldn't push it.And I would never follow ford's maintenance schedule.Because all they care about is that it makes it through warranty

i'm going to be doing my transfer case.And differentials, at twenty nine thousand two and from what i've seen, I probably should have done it sooner.I've just been really busy, but i've definitely not waiting longer

it's hard to see, but this is my transmission fluid, and you can see a little bit of sparkle, and it is very dark and I just haven't had a chance to really offroad this that much.And I drive really conservative so that I can get twenty miles per gallon, by the way, I am a manual transmission

sorry, i'm in phoenix and even with the rain.It's been pretty hot and I just didn't even look at my pictures after I took em

sorry, i'm in phoenix and even with the rain.It's been pretty hot and I just didn't even look at my pictures after I took em

So I went to a friend's house, and I realized that I had a small leak under my Bronco, and I got home and I realized I didn't put sealant on the transmission, fill and drain plugs, and so a little was leaking out of my transmission. So I just drained it, and I was basically I have a little bit of fluid left, I use the. Red line M TLV 70 - 75, and I was just gonna refill it with the old stuff, but it's actually still pretty dark. And I thought, I may have seen some floaties, although I guess some stuff could have fallen off of the bottom of the truck in it, and I didn't notice. But and I know you don't get all the fluid with the drain infill, but I was quite surprised at how dark the fluid was with three quarts of brand new red line in it i tried to take a better picture this time. That's out of the MT88 manual transmission with 29000 miles on it. So again, do your maintenance early and often? Fluid's a lot cheaper because I was dead in.I think i'm just gonna buy another three quarts.Even though it's seventy five bucks and even though this only has like fifty miles on it, i'm gonna put new fluid in it again.I'm gonna put a post up and see what people think

uh-oh what do you mean if you get close to 100 K don’t touch it?

Id say 100k miles is fine on plugs unless you notice issues yes it's a turbo engine, higher pressures, a lot hotter, but they're usually, the plugs are meant for that kind of environment and use a colder heat range etc... i had 2.0 eco boost that I went to 137k miles on the same plugs without needing to swap them.Before an asshole, red light runner totaled it.

The thing that's really surprised me on these new engines, which is like twenty twenty and up.It is the coolant degrading a lot faster.

My friends baby Bronco I think you have 47000 miles and his was crazy dark instead of the lime green, and we did the voltmeter. Test and it was way bad. I forget the readings, I think up to 3 mill of volts was acceptable, and his was at like over six, we didn't test the ph but I read online, and it seems like a lot of people are having issues with this new vc13 coolant going bad faster. So watch yours and check if it gets dark seems to be a good indicator.
