Thank You. Very Helpful And Doable For The Average Guy.

Why Mechanics hate Engineers

Tip: remove the negative terminal first. Also, on the battery box end closest to the front. If you lift up slightly on this end, you can pull the two side pieces out (held in by slits in plastic) which will give you a little more room to pull the battery out. Don’t forget to reverse TIS procedure when you have the new battery installed. Last, before reinstalling all the covers, test the battery (start the car).

This video was brilliant. Gear puller work’s excellent with PB Blaster. Saved a shite load of money! Took about a hour an a half to disassemble and reassemble. Back on the road! Horrible design and that’s my last ever Ford! Cheers for this video mate!

I truly appreciated the “it’s a pain in the ass comment” - the engineer that decided to place the battery in that spot needs to be fired. That said, excellent summary video. Followed step by step no it worked without a hitch. Thank you!

Tip for getting the wiper arms back on, there are two clear marks through the windshield that indicate where the wipers should rest. It also helped me to allow the wipers “knobs” to cycle and come to a rest after I had removed the arms. This video helped me quite a bit thank you.

Your video taught me how to replace my own bad batter and saved me hundreds of dollars, time, and stress. Thank you!

Just pull the filter box out, front cover of battery box, battery hold down, slide battery forward and disconnect

Torn between this method and the "official" method which involves removing the air filter. I went with this one and I think I am glad I did -- it only took me about an hour. I was already experienced with removing and realigning the wipers since I just did that a few months back. Thanks for the video.

There was nothing wrong with the battery swap, but if you do this job by yourself, you'll almost certainly run into problems. If you notice in the video, after he put the wiper arms back, they can be moved around. Typically, it doesn't work like that. Normally you have 1 wiper motor that drives both wiper arms. Both of them are connected together, so when one side moves, the other does as well. The wipers on this vehicle are different. Each wiper arm gets its own free running actuator that run independently of each other. On the older design, if you don't install the wiper arms exactly right, you can pull them off and try again. Not on these. The wiper arm actuators have to be recalibrated after you remove them. If you don't. they will crash into each other when in use. He most likely didn't turn on the wipers after he worked on the vehicle to confirm operation. To avoid this problem, you need to calibrate the arms with a factory level scanner and the procedure in the workshop manual for the vehicle. One of the other posters mentioned the marks on the windshield. They're calibration marks that are used in the calibration procedure. If you don't do all of this, you have somewhere between a 1% to 5% chance you'll get it right by accident. If you are aware that this can happen, you have a much better chance avoiding problems if you're really careful. Either way, always assume you'll need to recalibrate the system. In most cases, you have to.

This is a great video for this job, thank you so much for doing this. I was scratching my head and didn't want to pay the dealer to do this when I knew I could change the battery on a car, but these newer vehicles are a little intimidating when you look under the hood. (sure it's designed that way for that reason) So again, great job!

You can also rip the engine air filter housing out and just pull the battery out

I will never buy another car with a battery that is so hard to take out.

You can reset the bms by turning the key forward and then clicking the high beams and then the brakes. Look it up for the procedure but it's easy

Thank you for sharing this!!!!

Great video bro! But, I have to critique you just a bit. #1, A properly placed pry bar will pop those wiper blades right off. I watched a guy bang them with his fist for a good 5 minutes trying to get them off. #2 This is a big one that everyone misses, that battery box is NOT a solid rectangle. It is tight, but lift the front section up about 3/8's of an inch and it pops right off making the job MUCH easier.

WOW. My neighbor just asked me to help him replace his. Thank you for the video.

Great video!

Thank you so much. This is about to be a pain in the ass lol

And this along with the internal water pump on my Explorer is why I traded them in for a used Toyota. (And I've had Fords for 50+ years)

Trying to reset the BMS after a dead battery. We couldn't get the headlight flickering to work either. I guess we need to go to the Dealer. Thanks for the video.

What a pain in the ass just to change a battery.

Awesome thanks for the help man! What a PITA location 😂 I bet you could barely jump it without taking the cowl off if you needed to honestly

No way was I going to risk screwing up my wipers or breaking plastic clips to get at the battery when all you have to do is pull out the air filter box and unclick the front panel of the battery box so you can slide the battery out the front of the battery box.

How much did they charge you to reset the BMS?

What is the Optima battery numer?

i can not believe it all that work to replace a battery

I have 2017 ford escape ecoboost it has on and off button which is pan in the ass u kn how to disable it permanently

Mine was small.

This is insane but thank u I hate Ford I got to change my girls battery.....Goo Chevy💥💥💥💯

A well designed Ford battery replacement. i am sure the Chinese will copy that.

😂...yea ... Ford knew what kinda hell this was gonna be for the DIY community 😭😂😭😂😭😤😡😭😂

I can't pop off the wipers?! 😭

There is a faster and easier way. Remove the air box

I saw a video that shows a different method that doesn’t require removing the wipers. kzfaq.info/get/bejne/m7OfmpNn3NiaqWg.html

Looks good at home on a nice sunny day but a nightmare in a parking lot during a snowstorm. Ford sucks!

Engineers hate mechanics

ford screw up on this one...

Seriously, F Ford

Lol you skipped the hardest part
