2021 Ford F150 5.0 V8 Cylinder Deactivation & Oil Pump Belt Defeated! - It Wasn't All Bad... 

The 5.0 is definitely a great motor I have a 2013 with 270,000 miles on it no problems with the engine just regular maintenance

Placed my order today for a 2022 f150 5.0 and it’s now an option to cancel Deactivation. X52 is the option and it doesn’t cost anything. The dealer said it’s due to shortage of chips that has caused Ford to offer it. So HELL YEAH

Just got my 21 f150 stx 5.0 last week. Hope it won't be the last of the v8s. It has tons of power and the engine sounds awesome.

The battery monitoring system does more than decide about activating auto start/stop. It also varies the load on the alternator to provide the right amount of voltage to the battery depending on the battery charge state. With the monitoring system deactivated, the controlling computer thinks the battery voltage is low and will default to max charging all the time and not only cause extra drag on the engine it might over charge the battery.

Thanks guys I just ordered a 21 platinum and especially concerned about bypassing the aggravating start stop feature as well as 4-6-8. Great to see to brothers working together and foresure going to have a channel that will be hugely successful soon. Just don't let that successful screw up your brotherly love for each other. Thanks again

I have a 2016 rebel with only 36000 mile and it just started tapping , this cylinder deactivation is such Abad idea. Even if I fix it in still going to be worrying when will it happen again. Thank you for your in put im looking to change to a f150 5.0 . You help take away some fear. Will wait on more up dates from yiu guy. God bless.

Cylinder deactivation is the reason there isn't a new truck in my driveway this year.

I hope Ford never stops selling the v8

The problem with unplugging that battery monitor cable from that BMS sensor is that now you actually change the charge rate at which it keeps the battery charged in that vehicle now I'm not saying it's not going to be sufficient but the vehicle may see that as an issue and it starts shutting down features online that create an issue for the customer because it can't monitor the battery so it says you know what let's disable the passive entry system let's disable the door keypad let's disable ambient lighting these are things that are not needed for the vehicle to run if we can't see what's going on with the battery Now I've had people try to disable their auto start stop in older vehicles and this was a problem because they go up there and they unplug that or unplug the connector underneath that the trailer brake module to stop the auto start stop and then other things start disabling inside the vehicle and I had to track down what they were doing to put all that bad information to rest because it eventually down the road started affecting other things that were not working on the system Theoretically all you'd have to do is save a junk old battery just enough to get the vehicle to start leave the battery monitor on board with that bad battery let's just say 60 to 70% charge rate that that battery has or life I should say lifespan and it will disable that it'll start stop and active fuel management anyway and then take the regular battery and put it back in the truck and until everything is reset it's going to stay disabled. I don't know I just wanted to put this here so people have more information I don't think people quite understand these systems like they think they do it actually works much more complicated than what most technicians even care to realize but when you get into the description and operation on how the system works there's several pages of what that battery monitor system actually does it's more than just the few things that you mentioned in this video

Really like your channel guys. Thanks for great Ford content. I'm considering a new F150 and your videos are greatly helpful. I'm also a Mustang guy and have a 2012 Boss 302 (white on black) in the garage with just 25K all original miles. She's a keeper for sure! Stay safe and healthy.

Great information here Gents. Solid video!

Cylinder deactivation and autostart stop has been the worst thing to ever come to automobiles

So glad mine came with cylinder deactivation deleted. Best thing the chip shortage as ever done for me 🤣.

We didn't have a chain driven oil pump before. It was slipped directly onto the crank

My 2021 5.0 burns oil on every startup. It went from full on the dipstick to add oil after 800 miles. The truck has 3300 miles on it and is going in to the dealer this week.

That trick disabled auto start/stop, too? I am sold!

You guys do a great job, very informative. Thank you!

HELL YEAH! This is the kind of content I wanted to see about the 2021 F150 5.0 motor! I’m definitely considering a new F150 instead of waiting even longer to make my Bronco reservation into an order! I really like the SuperCab 4x4 5.0L with the STX package in Lead Foot Grey. Much love from Texas, y’all!

Thanx I wasn't happy that they also did away with steel sleeves in the cylinder walls. Ford said that BMW helped them with the new process of plasma arc the cylinder walls. Also a oil separator is a plus on this motor.

Keep an eye out for aftermarket dongles to fit between the 2 connectors for that as well. Great info, thx

I’m pretty sure you can go to auto zone and buy just a trailer plug and put it in and it will deactivate both the cylinder deactivation and start/stop. This is because when you are towing a trailer it won’t do either of those things.

Awesome now all Ford needs to do is mate the V8 to the 7.5 kw generator and I am in...from a GM Guy!!

Cylinder deactivation shines when you’re going downhill. When I would go home from Calgary to south of Kelowna (~680km) from a full 98L tank, I would have a quarter tank left. And I wasn’t always easy on the pedal, plus construction zones. Going back was sketchy on a single tank. I think I made it one time.

Great info brothers, this and my jlt catch can will be the first things I do on my 2021 when it gets here, I wish the aftermarket would get going on products for theses trucks, I’m hoping my S&B cold air intake off my 2018 will fit by just blocking the unneeded vacuum port 🤞, great video guys, love your channel so much, cheers

Got it,,,,, i ordered one for my new f150 when it gets here,,,,, great videos that you guys do !!!!!

Have you guys put out a video regarding 3.5 vs 5.0? Quality. Longevity. Etc. Also, thoughts on the hybrid vs. 5.0? Thanks guys. Keep up the good work.

Wow, that was easy. My Grandpa would have bought a 2021 with the 5.0, of course that stuff would need to go. My dad may be getting one in a couple years so definitely thank you

Great channel guys! Just picked up my '21 FX4 5.0 yesterday. This will be the first thing I do!

Just so everyone knows....the cylinders do NOT stop and start rotating. Only the fuel stops flowing to the cylinder....so the engine life is not compromised at all. The only thing compromised is sound....the exhaust sounds different when you have modified the pipes, and cyls are deactivated.

Great info, also I’ve yet to hear of any problems with this motor due to cylinder deactivation.

Very interesting! It'll be great when/if there comes a plug-in for that connection to deactivate, but keep the warning lights from coming on, etc.

I have a 2021 STX 4X4 . My truck doesn’t have the stop start feature. As a mater of fact it’s on my window sticker saying it doesn’t have it , of course there was a small charge added to the truck for the elimination of the stop start .

Doesn't putting it in sport mode do the same thing? I noticed that auto start and stop is disabled when you pit it in sport mode

Thanks! Just drove home my regular cab short box 4x4 coyote home last Tuesday. Really appreciate the gen 4 update info and quick tip on the cylinder de-activation. Hopefully something like the Range plug in module will be available soon for the F150. As an aside, I ordered it to my specs in November of 2020 and it just got here.

Great info guys!

Favorite channel on the tube!! Keep up the awesome content 😎

Thanks Backroad Driver. I really appreciate this information.

Two questions: 1) This is two years ago, have found any problems since? 2) This is a 5.0 L, does this apply to ALL 5.0L? I have 2013 F150. Thanks

Thank you guys you guys are awesome 👍

I just got a 2023 f-150 with a 5.0. it said on my window sticker that I paid 50 bucks to have auto stop/start delete from the factory…Nice

Coming back to this video because I just got my own 2021 F-150 XL SuperCab STX 4x4 5.0 in Lead Foot Gray! Definitely gonna do this and other things too! Gonna watch your exhaust video again next. Much love from Texas!

While I'm not a proponent of cylinder deactivation, in overhead cam engines, they simply use a cam profile change to institute it. It doesn't require the fancy valve lifters in an pushrod setup that often fail causing damage to the cam lobes. OHC engines either directly accurate the rocker arms, or use direct tappets. I just feel it's rather pointless when VVT already retards timing on all cylinders at the same time, also reducing fuel burn. Since 3rd gen, the 5.0 just isn't as durable a motor in general. The 2.7 may have an oil pump belt, but I've never seen one fail early personally, and it isn't common at all. Everything else about that motor is built like a tank, and stock to stock, it will hand a 5.0 it's lunch. That being said, the 5.0 is still light years better than any has motor from GM or Dodge.

I've got a 2022 5.0 KR on order, and only way I was able to get it scheduled to be built is if I added the stop/start delete option...wonder how that plays into the battery management system or if I'll even have that plug.

Very interesting guys. I love that you have man on the “inside”.

This is GREAT info ! Thank You !

Unplugging a wire one I can access its 2021 I can deal with that!! Nice job fella's!!

Poor Sam. Workers Compensation my brother.

16' chevy for two yrs,then new 19' tundra TRD, but now I'm eyeing the lariat F150 just undecided on the 5.0 or 3.5

On Auto Start Stop, you replaced 1 button push with a different button push.

What is the wear life of the belt versus a chair system? I got 392,000 out of my original motor and chain.

Love your content guys, just got my 21 5.0 last week and love it, I’m just curious, where do y’all get your information on the cylinder deactivation? Thanks!

So I read in the comments this doesn’t disable the cylinder deactivation, but running in sport mode does. So why not run in sport mode 24/7? What are the disadvantages of this? Why buy a tuner or supercharger when you can just use sport mode? New 22 v8 owner here

Just a thought but how did you verify it isn't deactivating any cylinders now?

I just tested this on my 2021 F150 STX 5.0 and can confirm that it does indeed disable auto stop/start. It DOES NOT; however, disable Cylinder Deactivation. I have a muffler DELETE and can hear it kick in and out as clear as day. So back to the drawing board for that.

I'm lost. They talk about cylinder deactivation but the comments say it doesn't deactivate the cylinder deactivation.

Can you set sport mode in forscan as the default drive setting to accomplish this?

I wonder what the carbon footprint of having to buy new engines is when they wear out 100,000 miles early.

I’ll be interested in seeing what the GEN COM line is signaling that alternator to charge at after leaving the IBS unplugged

I'm wondering if you can use FORSCAN to disable the cyl deactivation. Edit: I JUST watched him talk about FORSCAN lol

Great video guys

Thanks so much gentlemen! I have hated cylinder deactivation even since it was invented. Can you believe that GM has still not been able to come up with a better solution for the Corvette? I'm a Ford guy, but I do love the Corvette; all Corvettes (Mary Barra has ruined that company). One question about the F-150: will unhooking the negative terminal clip on the 5.0 have any effect on the ProPower lithium battery or generator, if you get that option too? I like the 3.5 twin turbo PowerBoost, but I would prefer to get the V8 if at all possible. I just found you guys today. Keep up the great work.

Great channel. Looking at the VMP superchargers because of this channel. Crazy question but how much was your gas mileage effected on the WOLF when you made the switch. That’s assuming you have driven a full tank of gas without Multiple burnouts.

I'd advice caution. This isn't some mechanical fix like a heater core valve fix for Ram trucks that is clear in consequences. Don't mess with sensors because you don't know what's behind the scenes and if codes were written in ways that handles missing sensor data. Modern car's electronics are complex, you might create a problem elsewhere down the road. "If it ain't broke, don't fix it" applies perfectly to electronics.

On my ram hemi 8 speed i just put it in manual mode and scroll up to 8th gear and the transmission shifts through all its gears like normal and bypasses cylinder deactivation. I wonder if you can do it on the fords? Trucks been running on 8 cylinders since I drove it off the lot. To me cylinder deactivation is just more headaches and really doesn't save you fuel. I still get 21 mpg doing 75mph on a road trip and between 16-17 mpg in the city.

Thanks for the video, like always good stuff guys. I’m definitely doing this right this second. Has Sam had a chance to test the falcons while towing yet? Cheers

I just pray by the time I get my new Ford 150 that V-8’s are still available.

Great information. Knew you would get it. Time for the super charger! (P.S. Did Sam exfoliate? He looks extra handsome today.)

PLEASE DO A VIDEO ABOUT 2018 - 2020 5.0 LITER F-150 ENGINE OIL CONSUMPTION.

The belt is similar to Harley Davidson drive belt... Deactivation cylinders turned into a failure for General Motors years ago because of the wear from firing and not firing cylinders and I believe I heard that Sport Mode turns it off while driving

I love Fords, I have two brothers, so I subscribed 👍🏾

Did the new rings solve the oil burning issue.

Is the 2nd gen 6r80 the most reliable set up out of the 4 gens? Is the 10 speed good now?

Great video ...are you saying the oil pump gears ready for high horsepower applications now? No upgrade required like you did on Brad's truck ?

Can you just pull the deactivation switch out of the dash and tie the wires together Then put the switch back in?I saw that done on a different vehicle

My 21 5.0 came with the auto start/stop delete option, I just have a blank where that button goes. This video equates cylinder deactivation to the battery monitoring system to the auto start/stop feature. Question is, does that mean I do not have cylinder deactivation?

IMO if it can stop a bullet I’d be surprised if it couldn’t hold up on tension pressure

Ford always insisted that wet belts are solid and they proved them out yet I've seen those belted disintegrate on the 1.0L Ecoboost. It's cheap and that's why Ford went with it. They are confident the belt will last the warranty period, that's it.

would they just get the 6.8 pushrod v8 out already

I just ordered a 2021 F 150 5.0. (in Sept 2021)... On the order form I deleted Auto Stop/Start. Will this effect cylinder deactivation? Does it void the warranty? Thanks for the videos!

Cylinder deactivation is good, here's how to bypass it so it doesn't destroy your engine. Disable your battery monitor so you get to click OK every time you start up instead of clicking the other button every time. As a bonus you don't have to be bothered by an alert telling you that your battery or alternator is starting to go bad, you get to enjoy the surprise no-start!

Great information on this engine thanks for sharing this information. Great video.

I wonder if you can disable that feature with ForScan

I think they upgraded ring packs because they've been burning oil since 18'. But then again you said in another video that yours is using oil and it's a 2021. so maybe they didn't upgrade them enough?

This never make sense to me and I’m a logical guy who’s done a lot of work on engines. I have two 5.0 F150’s 2012 and 2017. Why on earth would I want to run 4 cylinders instead of 8. If you have 8 guys working on a project and you tell 4 guys to go home you will wear those 4 out early. Let and 8 be an 8 and share the work . The engine will last longer. It’s as bad as the stupid shutting off and on at the lights all the time. The starter will not last. Oh and ask Toyota about timing belts on their v8’s back in the day. Has to be changed every 90k. Expensive job. These engineers have short memories. GM never mastered their engine deactivation issues for 20yrs and im sure Ford has it figured out. 😂😂😂. Laughable.

How is it going with the cylinder deactivation being unplugged? I’d like to know if you have had any problems with that? Thanks for your time

Great info

Thanks Gents! That’s some dangerous mods 😃....

Great video, did you finally give your truck a name? I still say Space Ghost!

Yeah, this turns off stop start. It has nothing to do with cylinder deactivation. This video needs to be amended or removed.

Looks like a compelling reason to buy the six cylinder eco boost instead. These new trucks and the prices they want are not worth it.

What's the service life of that drive belt and expected labor rate for someone who who have to have a shop replace it?

I have a 2021 silverado with the same, I bought a deactivation plug in module and to also stops the auto stop. And

What kind of exhaust do you have on this truck? Sounds great

Another thing that ford engineers have said as well is to use a slightly thicker oil like 30 weight or preferably 40 weight. 50 is recommended only for heavy towing or track use because of the engine load causing the bearings to possibly be split out and the film shearing. Ford for the mustang gt say to use 20 weight but a guy took it on the track but didn't use 50 weight and ford said racing is allowed but for that application the wrong oil was used. If you pay to get a bolt on supercharger on your 5.0 from ford they'll switch your oil cap to say 50 weight even though they didn't change anything else inside, just threw a bolt on in. That really tells you everything. Overhead cam engines can use thicker oil than the overhead valve in my new truck. I ran both 10 and 15w-40 in my old f150 instead of 5w-20 piss and that's the reason why my 5.4 lasted beyond 200k and without any oil burning or valve train issues at all. Ford later admitted that the thin oil is crap but they had to for cafe standards. In south America and Australia where they didn't recommend 20 weight for that exact engine is where they didn't have issues like over here. Thank goodness I used my intuition and still used thicker oil. I'd highly recommend ford's diesel oil for these gas engines or shell rotella. The anti wear package on both is one of the highest you can get at any walmart. And no diesel oil doesn't harm engines that dont burn oil. If it burns oil it will accelerate the poisoning of the cat but the both the anti wear package and viscosity of the oil is what prevents that in the first place however if you start using it before it burns oil. so do so if you actually care about your engine. Dont if you'd rather have been counter Gov regulations ruin your engine.

What can you tell me about the new "spray on" cylinder sleeves? Are they holding up or are they wearing out fast? I'm looking at a new(er) F150 5.0 V8

Do those same upgrades pertain to the 3.5 Echo boost, 2019 F150 lariat FX4

I ordered a 21’ to get away from the timing/vct issues that plague these engines. My 19’ had the tensioners replaced at 2k miles and now at 35k it’s starting to make the same noise again.

Is oil consumption still a issue with these engines and is Ford still building the 5.0 with plasma cylinders if this is the right term thanks

Ford Essex engine(5.0L) worker I personally hate the new look of the 5.0’s

How long is this belt for the oil pump rated to last? Miles/years? Sure it can take 1200HP but how long will it last?
