The flex is back and doing well, today we will be replacing the spark plugs and coils, i know a complete coil replacement isn't necessary, however in my past experience on higher millage vehicles there comes a time were you start chasing coils around failure after failure, after 2 strikes i replace them all while digging deeper, hope you enjoy
I want to personally thank you and your family for sacrificing your time to produce quality. Not everyone with the knowledge can teach. Thanks, you are a man of quality, who brings quality mechanics to every job. Stay true to your convictions, because success is yours, and what's yours is your families. Thanks for QUALITY !
Thank you, after watching this video we were able to change our spark plugs with relative ease.
But prior to changing the spark plugs we power washed the top of the motor and engine bay. We took our 2009 Flex SEL (and my Honda Civic) to a self-serve car wash and first we sprayed the engines with Simple Green, let sit for a five minutes, then sprayed clean with the power washer (on rinse). Cover electrical connectors with rags if you want to; just don't over do it with the power washer. And wait a few minutes after you finish power washing to let most of the remaining water evaporate off.
Now the engines look great and the Flex runs more smoothly with new plugs (108K on the orig ones, probably way overdue). Oh and we did oil changes on both cars yesterday. Tomorrow we will be rotating tires.
So nice to see you back in action.
ManicMechanic007 Thank you man, feels good to be back
i have two suggestions... blow air pressure down the spark plug hole before you remove the spark plug
to remove any loose junk...
Also might as well replace the pvc valve after you remove the intake manifold as its at the back of the engine and is a lot easier to replace with the intake manifold removed...
Thanks for the video! Coil pack 3 went out today. After watching your video I had the job done in about an hour. Thanks!!
Perfect instructions. It was exactly as described, didn't take too long to perform this maintenance as described
Great explanations of a lot of things many would overlook. Great job.
I want to thank you for a great video. I also want to thank you for a straight up step by step way to remove the intake and your advice on the anti seize. I used to be an ASE mechanic, how ever I changed careers in 1988. Lots has changed in those almost 28 years. I still have my tools and do what ever I can on my vehicles if I can. I will be doing this on my car as soon as the weather starts to warm up. No heat in the garage. LOL
John Benz you welcome anytime, happy I could help. it's nice knowing I have knowledgeable people subscribed to the channel, feel free to chime in anytime on other subjects as well. thanks again
Thank you for more videos. You were missed and I enjoy your videos very much.
Bediasman your welcome, and thank you for the kind words means a lot, i have truly missed everyone as well and all the interaction that goes along with it, i can honestly say one of the main regrets i have during this whole transition is letting this channel fall behind, any one close to me will verify that statement, im determined to try my best to pick up where we left off with hopes everyone understands, Thanks again
I personally appreciate your video gifts. Stay strong and just do what you can, we will sit by and just enjoy the fruits of your efforts.
Nice video as always. One thing you missed was the link that were going to put in the description. It's a easy thing to miss.
whatthedouch Thank you, im slipping links are added now
Glad the engine has held up after that water pump repair. That was a good call you made and it turned out in your favor. It's a tough decision to make especially when a so called 'pro' makes an incorrect diagnosis. Take it easy - Ozz
Thank you, I'm thankful everything has been holding up, my biggest concern after finding the root cause, wasn't so much the repair in general, but the fact the initial misleading diagnoses put that engine In a potentially catastrophic state, running longer than it should have with that failed water pump most certainly contaminated the oil in more than one way, the multiple oil flushes after the repair must have been enough, Couldn't be happier
good to see u back hopefully this time u will not let us waiting too long for the next video as always good info cheers.
Thank you, my goal is going to be 1 video a week, if everything goes as planned it shouldn't take me long to accomplish, thanks again
Good to see you back on here, Will! I really enjoy your videos and I know you have much more to teach us! Thanks and keep the great videos coming!
Thank you feels good to be back interacting with everyone, much needed support I truly appreciate it, will do
I sure miss ya man ! Super that the water pump held .. (I knew it would ) Great job man !!
ShawnMrFixit Lee thank you man right back at ya, wasn't easy stepping back for a moment but with hopes i can keep things together this time around with a less stress approach, i was extremely happy to see this one come back for service to have a listen and once over, thanks again man its appreciated
Don't worry about Utube , you and the family comes first
Things have finally started settling in, my kids are actually very supportive and been encouraging me to start back up
Help me out alot. Thank you for givng your time to share this video step by step. Trully appreciate it!
Awesome Will , glad to see you back. No Well Manufacturing up here in Canada ....
Steve Rob thank you, its good to be back, man i feel for you i cant say enough about Wells not only as a manufacturer of reliable products, they have real informative information in their videos that i know have helped me in many repairs, it says a lot about a company willing to put themselves out their sharing knowledge, great group of people
+robinsonsauto I agree. I love wells products. They're the only electrical brand I trust other than the oem.
Actually I've.never used they're O2 sensors. I stick with NGK or Denso. Any experience with wells O2 sensors?
Michael Herbert i honestly cant recall if i have, however i wouldn't think twice about giving one a shot, i just had a bad experience with a bosch the other day, it was cycling good but the ecm didn't agree with the signal, just came to mind when you asked, wish i had the cam rolling for that repair swapped out with another and it was good
Excellent as always,glad youre back
stv357 Thank you, glad to be back
It's great to see you again. Do you always put grease on the coil electrical connection? I've never seen that done. Interesting. Thanks for sharing your knowledge and experience. Its much appreciated.
Michael Herbert Thank you, yes i have used dielectric grease for many years after experiencing connection issues due to moisture, corrosion etc. with very good results. been stumped by connection issues that resulted in come backs and misdiagnoses, i have found myself slipping away from using it as much as i once had during general repairs, mainly because manufactures made great improvements on connector seals, but in general its a good practice especially when replacing a part because the connector seal has formed itself to the old part and may not seal 100% on the new replacement, its an extra line of protection, hope that answers your question
Now that you've done the water pump, you'll be changing out the PTU next... LOL
Great Video, glad to see the follow up on this one. Take care!
Barry Kelly Thank you for the compliment, im thankful it was a positive follow up
grasias por los videos y no nos abandones
martin arrieta su recepción, no se preocupe mi amigo ustedes son como la familia
Ty very much for this video buddy it helped out with changing my own spark plugs lol
Thanks for the help! 😊
good info on removing the intake...but please blow out the plugs with compress air before removing...to keep any trash falling in cylinder when plug is removed...
Great presentation step by step Tysm great job
Great video, I have the same Flex with a misfire problem so this was very helpful. Are you generally satisfied with the Wells products? I notice their prices are quite a bit less than the other brands, just wondering if the quality is good.
I only recommend removing battery cable first and keeping tools # ANY METAL AWAY FROM THE BATTERY Otherwise great video
i really appreciate your video my man! same car but it's 2012. thank you.........
It's so nice to see you back again and with an excellent video. I love watching you work as you are a conscientious and true professional. Keep {:-)
wysetech2000 Thank you for the compliments, its great to be back :)
Nice video as always.
john CR Thank you
I’m going to change the spark plugs, should I change the boots also 100,000 mile tune up ? Also great video,well done and thank you
You know, the windshield cowl gaskets on these cars (heck on all Fords) are infamous for failing after about 5 years. Apart from the bizarre vibrations/noises that causes in the Flex's air conditioning ducts, could that same bad cowl gasket be letting water onto the rear heads?
Thanks for the video, good to see you.
Duncan Mac anytime man, thank you
moisture can come from underbody automatic car washes. I had two plugs and coil packs on an escape '01 fail on the rear bank , plugs were rusted too
3.5 ecoboost to be precise.
Is this with the turbo or without?
Excellent video, don't know if I might have missed it, how do you determine which coil is bad?
Go to auto zone or advance get a free system check mine was cylinder 3
Do you have any videos on replacing an alternator or serpentine belt on a late model Flex, Edge, or Explorer?
How do you remove the clip? I couldn't see with your hand in the way. Where on the clip do you press?
did you have a check engine light on? I don't but my performance is horrible and gas mileage
What is the numbering for the coils? I have a 2013 ford explorer v6. I can't find the coil numbering!
How do you determine which coil is bad? sorry for the previous comment typo it's 0200hrs
I went to the ford dealership and the guy told me to do an injector flush when I do a tune up, he said it helps and you have to do it. And then tells me the charge is $300...that is asinine. Would you recommend doing that injector flush?
No. Well, no unless you routinely leave your gas cap open and physically removed your fuel filter.
Honestly, you should only need to add injector cleaner to the gas tank about once a year or once every other oil change
sorry..
my two suggestions below are for a 2016 ford flex ...
Where did you apply the marine grease and is it dielectric?
Where did you get that ratchet I’m fixing to have to do the job this weekend that ratchet That ratchet would be nice to have
I am planning on replacing my ignition coils on my 2009 Ford Flex. Has anyone used the following coil: AIRTEX/WELLS 5C1652, and if so are they any good?
My check engine light just started blinking what do I do
you ever do an alternator on this car?
Is there a gasket between the upper and lower intake manifold?
yes there is, plenum gasket, if it is damaged replace it or make sure you have one on hand, i would change coils plugs and other things since i won't be going in that area for awhile
