Mazda6 3.0l spark plug change

Changing my 05 Mazda 6 spark plugs. Has a lot of miles on them. Sorry if I missed a few things, but you get the gist of getting them changed. If you have any questions let me know, I will try to help out all I can.

[@TheJimgonzalez]

Thanks so much Brutmaster08. I watched your video over and over, as I repaired my wife's car. It was surging, and ran a scanner on it, and it was the coil in #3. I busted the hose that went from the throttle body to the firewall of the engine. Anyway, the dealer sold it for 35 bucks. However, even though I ran into my own issues seeing the video over and over again was all the help I needed to get the job done right... all thanks to you. Now my wife is happy again, as her car is running smoothly, even though she only drives about 200 miles a year,lol.God Bless Man.

[@brutmaster08]

Nice work, very happy to help you out, its the reason I create these videos. I want to help out all I can since going to the shop cost so much. Good work!

[@davidniemann6256]

Just completed the job on 2006 Mazda 6 3.0L! Had a code P0301 on cylinder #1. Just replace the coil, it is not worth your time to diagnose. Autozone will do a free code check and the code will tell suspect cylinder, mine happened to be #1. Also,some suggestions. The two hoses connected to the throttle body were easier to remove by disconnecting the other end of the hoses. Access was adequate to remove clamps and did not remove Battery. Also get a new gasket for the EGR valve, same material at the manifolds but circular. I did however re-use the one at the EGR connection. This video was accurately captured and of great help.

[@NintendoSamurai]

Just changed mine last night. Literally the best video for this by far from what I've seen. Thank you so much for the guide! Car purrs like a kitten now. For context, they had never been changed before. 260000 km on them.

[@brutmaster08]

Nintendo Samurai Hey brother, happy to help you out, have a great one, safe travels! Thanks for watching! Brutmaster08

[@NeitouSama]

Sorry for the lack of reply! I forgot to plug in the TPS sensor on the throttle body! xD After I plugged it in I turned back on the car and it runs beautifully! Thanks for you help! I broke that red tab though...that thing is a nightmare trying to get off!

[@KIDZODIACVR]

Bought this Mazda 6 v6 3.0l 2006 with 94k miles and at about 104k now. Teaching me a lot about my car, only been driving for about two years and its good to know these things for the near future. Thanks for the help man!

[@brutmaster08]

Happy to help, your very welcome. Have a great one!

[@dougtom5824]

It's a good video. Useful hint for those removing the EGR valve - the nut attaching the exhaust pipe is threading back into the valve. All you need to know is that when you have the crescent wrench on the sucker, turn it clockwise to loosen.

[@rodneyamian]

Brutmaster08... the coil change went perfectly! Well, not really perfectly, had to fight with a couple hoses and connectors, but other than that, it went exactly as your video, minus the spark plug change. (got those replaced by the dealer earlier... if I saw your video sooner, I would have done those myself too.) The car runs great, the check engine light turned off. For a guy who has only recently started working on my own car... this is a big deal. Thanks again, and awesome video.

[@surgically_fit]

Thanks for the vid. It made me realize to check the simplicity of changing the spark plugs before I buy my next vehicle.

[@noelwedderburn1201]

hi brutmaster; thank you for that video, because of it I was able to change out all 6 of my spark plugs and the coil on plugs this pass Saturday. the hose on the bottom of the throttle body was a bit difficult to remove, so I just unbolt the throttle body from the manifold and leave attach to the throttle body that hose and it work just fine. thank you once more.

[@brutmaster08]

noel wedderburn hi you are very welcome, happy to help you out. Good work.

[@kelvinfeliciano]

It is the negative terminal first.... Because when taking the positive out you could touch ground and kabumm blowms fuses of burn wires or even computer. Oil in the spark plugs are rubber for the spark plugs . the come with the valve cover gasket kit.

[@brutmaster08]

Hello, No it will not make smoke puff out of the exhaust, it causes burning oil smell in the cabin of the car and under the hood when it gets hot.

[@brutmaster08]

Ok, it is the Starter. Mine has been doing it for over 100,000 miles. So far still working good.

[@brutmaster08]

Ok after a little research I see they refer to under the back seat. There is a black cover with a wire coming out of it. Remove cover and filter is there. But they say it pricey to replace. I have tried to see where to get a filter and no luck. People on form say the filter is part of the basket assembly, so your buying the whole basket assembly. .....Fuel filter I am thinking of might be on the Ford Escort. LOL. Hope this helps.

[@brutmaster08]

Your welcome, hopefully it is nothing major and can get her running 100% again. Best of luck!!

[@brutmaster08]

Your very welcome, and yes I did replace the intake manifold gaskets. Manufacture recommends this.

[@brutmaster08]

Every electrical connection I removed was needed to get intake out. I would just shoot some carb cleaner in the throttle body. I used anti seize on the threads because where I live the temp can go down to -40 below and up to 100 degrees. The temp changes so much and with all the salt they use it causes corrosion about everywhere. Don't want them to freeze and rip the threads out if I need to replace them again. Best of luck with our project!!

[@nickaustinnoble]

Thanks for the video. Made the job super easy to do

[@rodneyamian]

Great video, looking to change out the back 3 coils on my Mazda6. This vid gives me some confidence that I can do this myself. Dealer wanted $511 to change them out... obviously I told them no. Was going to find another shop to do it, but I think I should be able to do this. I'll let you know how it goes.

[@madjwills9045]

Rodney A did you ever get the plugs changed?

[@brutmaster08]

Thats great you got her purring again!! Yeah that tab sucks!! Always here to help, not an mechanic, but know cars really good. Have a Great rest of 2012!! Brutmaster08

[@RussMeister70]

thanks for uploading. one website ww.E-HOW.com said to disconnect the battery , put thwe plug wrench pon and turn counter clockwise to remove . then put the nerw plug in and trung clockwise lmao. GEEE never thought of turning the darn wrench. i think anyone even anoob knows that. they neglected to mention the intake manigiolf. even autozone said all i had to do was " unscrew one plug and replace it " lol

[@brutmaster08]

I got the Bosch IR Fusions, but other good choices are NGK and Autolite(what came on that car). Other than those I would stick away from them. Just my 2 cents. Good luck, thanks for watchin!!

[@brutmaster08]

Yes the valve cover gasket seals are failing. Looking to replace them soon...some 40k later. LOL. Time just flys by. Thanks for watching.

[@brutmaster08]

Hi, just got back from vacation, it took me about 4 hours. I took my time to make sure I did not mess anything up. If you know a little about cars, go for it. If you need help, watch the video, or ask I will help all I can. If you are kinda scared to do it then don't let the pro's take care of it. Good Luck!

[@monkeyNUTsagg95]

If you would give the names of each HOSE/CONNECTOR as you go along disconnecting them one by one. Adding a brief description of its purpose for each through out the video! Wow! You would have, THEE MOST RESOURCEFUL video, EVER! That would help and answer a lot of unasked questions. You'd be like the Car God of Mazda!! Well it would help me anyway. Thanks Mazda God

[@chagodlee]

Okays thanks for the part number. Yah well im thinking its gonna be worth it to change coils and spark plugs, since its not too costly. And hopefully it fixes both problems haha. Thanks alot for all the helpful advise. ill let you know how it works out!

[@nekko1431]

Very helpful video. I am going to try and tackle this my self here in the next couple weeks. Does anyone want to band together and find the engineer, take him out back to the wood shed for a few lashing. No reason you should have to go through so much trouble just to change plugs. I recently acquired a 1982 GMC Van with a inline 6 and changed the plugs in that in 15 minutes.......crazy.

[@HangryPanda90]

nekko1431 I'm in....

[@andrewstratton7095]

Well that's the difference this isn't a straight 6. This is a v

[@MrCory200]

just thought id let you know that in order to make a computer to almost fully relearn its self you need to turn the ignition to run position for 15 min then remove the key from the ignition. Hope it helps, and ill try and dupe this and look into it further.

[@praneethrv]

Thank you for sharing - just changed mine and it was harder than I thought, but happy nonetheless.

[@mouneek99]

that's what was kinda thinking too. Can only hear it in the am. after that its gone........til next morning lol.Thanks!!!!

[@MauriR6]

Yea Its too bad. I bought the car at 69k miles, it now has 93k. Hopefully when I run into some cash, ill get some real engine repair done on it. For now, its my secondary vehicle that I use only in emergencies, so hopefully itll last me a bit more before I have to do some major repairs. Thanks for the help

[@brutmaster08]

Yeah, I did, just have not had the time to fix problem. Thanks for watching! RA

[@brutmaster08]

The I4 is simple as cake. Remove plastic cover, unplug coils, remove coils(do not mix them up), then remove each spark plug. Install new plugs...not too tight. Install each coil where they came from, install coil wire, install plastic cover, and start it up. My bro has an 07 I4 and put the Bosch 4504 in there. MPG went from 26 to 28, put an K&N cold air went to 29-31 depending on driving habits. If you need a video, let me know, will make one tonight.

[@brutmaster08]

Thanks, figured that out while ago, forgot to post....new seals still sit waiting to be installed. LOL Trucks taking too much of my time. If/when I get to it..new video. Thanks again. Brutmaster08

[@brutmaster08]

Hi, it means the valve cover seals are leaking. Thats what mine is doing, have to removed whole intake again on my V6 and replace them sometime. Wish I knew that when I replace the spark plugs.

[@brutmaster08]

Your very welcome, good luck. Thanks for watching.

[@goldwolf0606]

Blow back might be causing the oily spark plugs. Maybe your pistons or the cyl walls are starting to wear out.

[@brutmaster08]

I would say check the MAP Sensor, and Vacuum lines. Thanks for watching, Good Luck! RA

[@brutmaster08]

Hi, it took me about 2 hours or so, I took my time. Depends on how mechanically inclined a person is. Thanks for watching. Good Luck!

[@brutmaster08]

Ah, thats rights, just remembered who you are. LOL Best guess I remember is its on tire firewall near the driver side. Let me look into it and I will get back to you this evening. Brutmaster08

[@m.t.v.7934]

Man I broke so many hoses and connectors when I did this job with my brother on his car, the plastic was so damn brittle and crap just snapped off. What a pain in the ass it was.

[@brutmaster08]

Your very welcome, tat line you want to know about is on the back of the intake correct? Its part of the Vacuum system if I am correct. Looks that way. Always here to help.

[@crv5322]

Oh crap. Taking mine to a shop!

[@MichaelMyers9092_]

Cr V too hard to do it yourself?

[@brutmaster08]

Hey, thanks, If I am correct, for the 3.0 cylinder 6 is the front most right. Open hood, looking down at engine it would be the bank closest to you and the far right cylinder. Best of luck. RA

[@brutmaster08]

Well I got my car with 55k on it and drove to 137k, I have seen people replacing spark plugs around 60k, while others like me drive way past that. I would say that they are probably original. Here is what I bought for coils..have not installed yet though, waiting to get the time to: IC 23 02-07 just google that and click on amazon. I have read some shaky engines and after new sparks and coils they were fixed. Hope that is a good fix for you, any least its due for replacement.

[@brutmaster08]

Cool, was thinking the same thing, I have the parts already, have to find the time to make a video and install them. Hopefully before May if over.

[@brutmaster08]

Your welcome, make sure to get the IRIDIUM plugs. The Bosch I see are on sale.....rebate.

[@azmotortrendz4524]

wanted to see how you took the manifold cover off but you skipped it :(

[@brutmaster08]

AZ Motor Trendz Hi sorry, if your talking about the plastic cover, it has 3-4 10mm bolts. Good luck, thanks for watching!

[@brutmaster08]

Hey, it might be a motor mount, check that first. My brothers ZX2 was shaking bad, mount was SHOT. Try that first, other than that are any lights coming up on dash? Your welcome.

[@brutmaster08]

Well not too easy...have to remove the intake to replace the rear valve cover seal. When I do it, I plan to make a video.

[@brutmaster08]

Decisions are hard, I love my mazda6 too. I have not really modded my car yet, I just have concentrated on my truck some...payments get in the way. LOL. I might get a cold air intake in the spring will see...at 158k it might need other repairs since almost everything is original. Best of luck with your future. Brutmaster08

[@christophers3408]

wish you showed more on how to get to the rear pistons. Got to fix 1st piston. No idea how to remove the rear guard

[@TheBruceMagnum]

The best spark plugs to get are the Autolite Iridium XP, better performance and mileage.

[@brutmaster08]

If I can find some time this weekend I will video how mine is hooked up.....looking to sell cold air? What brand? If I don't get to it I will try some night next week. Getting some truck parts back so want to start to get to putting it back together.

[@brutmaster08]

Glad you like, wish I had some when I started workin on her. Have a Great day!!

[@brutmaster08]

Your very welcome, good luck, Brutmaster08

[@brutmaster08]

Wow, here in NY they would never pass inspection like that. I would get an scanner and scan the car yourself. Or take it to Autozone they can scan it for free...last I heard. I spent a little bit and got a scanner that uses an computer. Lets me see everything running on graphs. Good luck, keep me posted, will try to help all I can..with out actually working on the car LOL. Brutmaster08

[@brutmaster08]

Hi, it could be a coil going bad. Is the service engine soon light on? It can also be caused by a bad spark plug. I have helped another utuber and got his working great again with new coils and plugs. BTW Thanks for watching and you liked it. Creating good videos is hard. Let me know if you need any other help. Brutmaster08

[@brutmaster08]

Darn that stinks, so it's burning oil bad? How many miles on it? Sounds like a previous owner did not car for the car that good and let the oil get too low. Good Luck changing them out, best of luck. Let me know if you need any direction. Make sure you finger start each spark plug until its in to prevent cross threading. Also don't tighten too much they only take a little bit. I am away right now so some reply might be not fast. Randy

[@brutmaster08]

Your welcome, good luck figuring it out whats wrong and getting it fixed. Brutmaster08

[@NotSoIncredible]

Oil leaks into the spark plug well because of the failing valve cover gaskets, you already have the intake manifold out, why not open up the valve cover and changes all the valve cover gasket as well.

[@brutmaster08]

Tell me about it...replacing the spark plugs was pain enough...wish I would have known when I had it all apart..oh well. Hope to get to once I get my engine back in the truck and running again. One project at a time.

[@brutmaster08]

Hi, No glue, just new gaskets and put it all back together. Worked great. Thanks for Watching!

[@brutmaster08]

Thanks, you very welcome!! Have a Great New Year!!

[@chagodlee]

About 6 months ago the CEL came on. Forgot the code but it was gas cap one & possbile vaccum leak? But i cleared the code and it has come on since then. I forgot to mention mine has 97,xxx miles had it over one year now. Not sure if the owners before did coils/sparkplugs. What coils would you suggest? Yeah no problem! Yeah good videos are hard to make & find.

[@rangersasc]

Always remove the negative terminal first by the way :)

[@jackalbytenpc5946]

oil on the spark plugs, might wanna change your pcv valve while you had that intake manifold off but yeah, try changing that out next time see if it helps

[@brutmaster08]

Hi, you might have dropped some dirt down the holes and it burn it off or moisture got down there. Or there was an oily residue on the spark plugs and it burned off. Brutmaster08

[@brutmaster08]

With a 05 Mazda they are coil over and they can be replaced at one at a time. There is no wire but the one that connects to it. Hope that helps. RA

[@Mints101]

The engine light doesn't come on. Everything works fine. I bought the car at 83, 300+ miles, now it's almost 85,000miles. Did an engine oil change, but that was happening before. If I don't change it, will it cause permanent damage to the engine. Thanks for replying back.

[@alext7772]

Might add that the torque spec for intake manifold bolts are 13-16 ft lbs.

[@NeitouSama]

Well yeah I mean if you mod the car you get better gas miles as long as you have mazda reprog the MAF I plan on throwing a bolt on exhaust and a INJEN cold air intake on the mazda, but the 06 eclipse gt (not the one from fast and furious its the newer one) is soooooo nice but I love my mazda too I just dunnO!

[@pjcolombo11]

This was a pretty good video...thinking about attempting it myself on a Mazda6 with 186000 on it...how long did it take to do this?? A lot is involved with removal of the intake manifold...and I did buy new gaskets for that....just wondering if its not easier to let the guys that do it all the time do it??

[@MauriR6]

Hey, I have a 2003, and want to change out the front three spark plugs and coils. Not mechanically inclined at all, but watching your vid, it looks pretty easy! What tools do I need exactly to be able to change just the front three?

[@NeitouSama]

Yeah thanks I appreciate it! One thing that kinda bothers me is she keeps throwing out the engine check light which is showing up at autozone as the TPS sensor or oxygen sensor but it goes off and on it's not consistent so it's really weird...it's like ever since I forgot to plug that thing in ya know? One autozoner said the plugs may not be spread out enough IDK. Also one last question. I adore this car I sincerely do but I also have a spot for the 06 eclipse gt spyder any idea why this car

[@brutmaster08]

@KrowiSutek The starter is going bad...but mine has been doing it for about 3 years and I put over 24k a year on her. I figure with a stick shift if she dies I can just push and off we go. LOL Its like the starter is over revving after it starts or its dry. Car is too compact to give a care until it starts to make a different sound or dies. If it dies...another video. LOL Good Luck RA

[@brutmaster08]

Your welcome, Happy Driving! Brutmaster08

[@SR-pb6kq]

You should've disconnect intake boot from throttle body and that would saved you time and work.

[@brutmaster08]

Sounds like its misfiring. Like a coil is not connected right or a spark is not firing right. Check all the wire connections to the coils. Did you replace coils too?

[@brutmaster08]

Ah that sucks, good luck figuring out what you got hooked up wrong, or not hooked up. Sounds like a vac line maybe.

[@tyrantfuryre]

I didn't know Jeff Goldbum did auto repair. lol .;)

[@MauriR6]

I have zero tools! I planned on going to Autozone, since they loan tools for free. As for the plugs, yea, the engine is in BAD shape! Ive been having to change out the front spark plugs every 6 months or so (dont drive it much, maybe 5-6k miles per year), because they get drained in oil and i keep getting missfire codes on two of the front cyliders. I figured this time, i'd change them myself rather than dish out $200 like the last time!

[@9829544]

nice, i hate how mazda makes it so hard to get to little stuff done lol.

[@brutmaster08]

Hi, first thanks watching, that noise if from the starter, has done it since I got it with 55k on it. Now at 172k, and does it here and there. I figure don't really care, its a stick shift, I can start it if starter fails....unless parked totally wrong. LOL.

[@826quique]

And thank you sir, very helpful video.

[@BPoweredLove]

10:50 Whew! I was expecting the engine to burst into flames for some reason

[@SR-pb6kq]

Also what about intake gaskets? Have you changed them? You didn't mention changing the lower gaskets to eliminate possible leak, and this part is not the easiest one.

[@TheDOM900]

Thanks for the video! Did you ever figure out why there was oil all over the plugs? If so what did you do to fix it, I have a feeling I'll have the same problem..!

[@brutmaster08]

Hi, yes the oil is from the valve cover seals leaking. I hope to get fixed soon. I am up to 174k and no major issue, but need to replace them before something does. I will post a video when its done...maybe this winter. Thanks for watching, good luck!

[@italiano100]

Great Video... I have a mazda 6 V6 too.. I have done my front coils and the rears I paid over $550. Is there a seal or gasket that needs to be replaced on the manifold after its removed?

[@brutmaster08]

Hi, yes there is a gasket that has to be replace on the intake manifold every time you remove it. Cost like $20. Thanks for watchin and Merry Christmas.

[@NeitouSama]

Sure wish you would've showed how you took off the manifold I can't get that damn thing taken off I've loosened all the bolts everything but it won't budge

[@roxyboarder41991]

Can you make a video on how to install the stock air intake? or more specifically where the vacuum lines and such go? I bought my car with a cold air intake and I want to switch back, but can't find much help online for the install of the stock intake. Thanks

[@lldeleon]

Thanks for the video. Did you have to replace the intake manifold gaskets?

[@brutmaster08]

Hi, well to start off with do you have any wrenches, extensions, or spark plug socket? If not, it might be worth to take it to the shop. Unless you plan to start working on vehicles more. How many miles are on the current plugs? and why you want to replace them and the coils?

[@brutmaster08]

Ah sorry man, look all around it, something has to be stuck...or give it a good tug if you are sure all bolts are removed..one could be hiding.

[@snowmobiler86865]

if the plugs are sitting in oil after you pull the COP off your head gasket is going out... nice video though!

[@TheNohar123]

Great video maybe u can help me i have a 2003 madza 6 and i need to locate cylinder 6 to replace the coil pack and plug because of a missfire is it in the front 3 or the rear thanx

[@brutmaster08]

Any luck? Hope the best!!!

[@brutmaster08]

The seal in the valve cover is failing, Hope to replace them soon, loosing more oil.

[@jerrysanches123]

thanks for the video very helpful..

[@Mustach_Mike10]

You have bad o-rings in the valve cover it looks like that's not sealing the oil from leaking into the spark plugs I'd think

[@NeitouSama]

Like last night when I just replaced the front three everything was fine just I didn't properly seal the manifold so the can ran real rough, but now everything's bolted on, all switches properly attached all tubes connected everything and nope it keeps going from 1,000rpm to 2,000rpm it's intervailing between the two and it will not go past 2,000rpm there's absolutely zero power.
