Subaru Legacy Outback 3.6R EZ36D Spark Plug Replacement

[@OutbackBowhunter]

I used this video as a template for how to change the spark plugs on my ‘13 Outback 3.6R that just hit 60K miles. I found the video to be immensely helpful, also with preparing for the job by getting the required tools. In my case just the short extensions, which made the work fairly straightforward and simple. I appreciate all your videos on the EZ36D, so thank you!

[@MrSubaru1387]

You’re welcome!

[@christopherpcline]

My tip: if you're doing the 2015-2019 models, start on the driver side rear plug, it's the hardest one to access and if you leave it for last it's going to be more painful than if you do it first. I also found it easier to unclip the lead from the coil packs and remove the coil packs entirely. My one gripe is why the hell is Subaru using so many bolts to hold the battery carriage on these? 6 bolts! The two side mount bolts are nearly impossible to get out unless you're under the car and if you have a ratcheting wrench this is going to come in really handy for those.

[@YeahBubbaGaming]

100% regarding the side mount battery carriage bolts. Once I pulled those things out they went straight to the trash. I never want to mess with those two bolts again, four is plenty.

[@erotunr]

Argree completly, Just did mine. It took me around 5 hours in front of my apartment. 15' outback 137,867 miles. thanks for all your videos, they helped me in buying my first Subaru

[@anonymous..-]

My guess is that it's a structural band-aid engineering came up with. It makes no sense as a battery tray alone.

[@CanadianCarpenterQc]

Thanks for the video, the only tricky part for me was removing the back coil on the driver side, I had to disconnect it and move the wire to the rear to be able to take it out. Very helpful! We want more 3.6 tutorials :)

[@IRWAutomotive]

Thanks to this helpful guide, I just did the plugs on on my 2017 Legacy 3.6R. My vehicle appears to have a slightly different battery tray, because I also had to remove the metal tray under the plastic one to gain access to the coils, and there are two side-mounted fasteners that I cursed and swore at a lot, but later discovered they're easy to get from underneath. I also had the hardest time with the back plug on the driver side, but overall it wasn't as scary as it looks.

[@MrSubaru1387]

Glad to help. 👍🏻 Yes, the 2015-2019 chassis/engine bay is slightly different.

[@toddyamaoka6701]

Same challenge same cursing

[@Ken-xj5cu]

Won't admit how many times I watched this. Finally decided to do it. Success! Note: Since Snap On truck doesn't stop at a DIY house, I will say Koken spark plug socket and extensions were the best! Take a mental break before touching that rear drivers side plug - you'll need the energy and patience for sure. Long live the internet - thanks Mr. Subaru.

[@camrsr5463]

Ah, the joy of 6 cylinder far side plugs! That will never get old!

[@janecaldwell4223]

Thank you for this video. I changed plugs in my Legacy 3.6 by carefully writing down the steps in this tutorial. I then carefully followed them. The battery tray with its numerous bolts holding it down was a bit of a challenge. I was too lazy to remove the engine bottom cover; however I used a extension ratcheting socket after using an offset to break the bolts loose where the tray attaches to the frame. Next time I change the oil I will put those two bolts in place. The main reason for doing this was to not have to remove the tray again if there was some issue with my spark plugs/coils. Everything worked great however. I did need to use a smaller ratchet for spark plug removal in conjunction with 1" extensions and I removed the coils on the driver's side in order to get more room.

[@altern8nrg]

Thanks for all of the great videos. I just completed this and came back to see how I did in comparison. For a non-pro wrench, I'd say ok. Much less time than several quotes I received. I don't remember ever having them done(maybe 60k?) and got the changed at 145k. There was obvious loss of power and poor fuel economy. The difference is very evident. O² sensors are next! But four at once is going to hurt. I removed the coils completely and wiped the boot down with some silicone lube on a cloth. DE grease on the harness clip. Smidge of high temperature anti-sieze on the plug threads. They were quite rough to back out. Smooth as silk to reinstall. I found the drivers side was easier than the passengers, but it was the first time doing it on a Subaru.

[@4skully]

yeah I need to think about the oxy senors thanks for the reminder. Going to be ordering them soon.

[@mikechurch4703]

First of all thank you sir for uploading this. My wife’s 2011 3.6 had 2 misfire codes now the transmission jerks intermittently (especially up hill). The dealership where we bought it new quoted a new transmission was needed due to “a bad main bearing”?! I’m thinking this is a rouse. 181k and the plugs need changing again. Hoping it’s that or an intake gasket leak. I’ll be leveraging this video to do it. Thank you again sir.

[@mikechurch4703]

holio ... Absolutely.. It was nothing more than a battery replacement. The car would start however there apparently wasn’t enough power in it to run the operational electronics correctly which impacted the shifting of the transmission. Proudly, I was able to figure this out myself a few days after this post. That was 7 months ago and the vehicle has performed perfectly since the replacement.. Perfectly. This is why I will take time that I can ill afford to spare to diagnose and repair my own car if at all possible. Great vehicle...blood sucking dealership. They will never again get my business and I tell everyone I know, not to go there.

I replaced spark plugs on my 2005 Subaru Legacy BP5 along with this video. The entire procedure is not exactly the same with this engine tho, just slightly different.

It doesn't look so difficult. I would have probably done some cleanup while the parts were removed, particularly on the one battery terminal.

Yes, get the iridium, they're worth it. The fewer times you have to do this the better.Plus OEM are iridium and its generally not advisable to "downgrade".

@@SergeiTheAnarch yeah after looking into it, the 3.6 uses ngk laser iridium, which are usually a 100k mile plug but in this case they are only 60k mile plugs.

@@wrf8245 I have the 5EAT, I snagged a 2014 3.6 since I hate CVTs. Holding up well besides the usual wear and tear; might look into aftermarket transmission (shifts are kind of slow) since the ultimate goal is either twin turbo or twin charging it once the engine starts to need a lot of work (might as well overbuild it if I have to rebuild it). Recently replaced PCV valve and will be replacing the PCV hose since I guess it got melted at some point. Subarus generally last a long time if you follow the maintenance schedule and avoid the NA 2.5L engine.

So I replaced my spark plugs last night 2010 Subaru Outback 3.6 and I just drove it around the neighborhood to let it reprogram itself and when I put it in reverse to back into the garage it acted like it wanted to stall out it is an automatic. Is this because it was not driven long enough and did not give it time to reprogram?

[@MrSubaru1387]

There is no reprogram for spark plugs.. You replace them and drive. Either there's an issue with the plugs/colis from the install, something was left disconnected, or you have an unrelated issue. If you took the battery loose, check the throttle body. It may need to be cleaned and then have an idle relearn procedure performed.

I guess the 2.5 engine is about the same for the replacement of the spark plugs. I also have a 2012 Forester and shouldn't be a huge difference, right? Also, I have a humming sound that comes from the rear part of the 2014 Outback. I've heard that the wheel bearings are a weak point for Outbacks but the wheels didn't have any freeplay when I lifted the car. Do you have any videoas for that??? Thanks for your videos man...

[@MrSubaru1387]

2012 will be an FB25B rather than an EJ253. So, slightly different. Plugs go in straight from the top of the cylinder, where this goes at an angle. Check out my WRX/Turbo spark plug video. It'll be closer. To find a noisy wheel bearing, you can drive down a back road, alone, get to about 45 mph and swerve back and forth slightly. You should be able to hear which side the bad bearing is on, if you have a bad bearing that is.

[@briangirouard7006]

Hey man, just discovered your videos the other day. GREAT JOB! I did this same plug replacement the day before finding your video. I had searched all over tying to find the correct torque spec for the plugs and the best I could find was NGKs site which listed this plug in aluminum head at 18-21.6 left. I decided to tighten to the 21.6. The question is, is this too tight given you state they should be at 15.5 left. Basically will this cause potential harm to the head, cylinders or shorten the life of the plugs. Would you recommend taking it apart and backing off to the 15.5. I would hate to but want it to be correct and I should be quicker the second time around. Your advice would be greatly appreciated. Thanks in advance

So I just did new plugs on my 2015 Legacy. Didn't use Subaru branded NGK's, but used the NGK model specified in the service manual, which matched what came out of the vehicle. After I got the new plugs in, the car was idling bad, and the check engine light came on. I panicked and replaced the new plugs with the old plugs. Then I realized the ECU probably just needed to relearn air/fuel mixture. So I probably just re-swapped for no good reason. Is it typical to have bad driving conditions (poor idle , hesitant acceleration) for a while after plug change? Or did I just get a bad set of plugs from Auto zone? Thanks!

Mate I’m getting similar issues on my Aussie ‘09 3.6R Outback - intermittently jerking under moderate load. Was planning to do the same that you’ve done. Glad it worked for you, we’ll see if I have any luck!🤞🏼

[@hunndy]

@@benbassett1124 how did it go mate?

[@benbassett1124]

@@hunndy yeah really well. The jerking/miss has been resolved now. The plugs looked worn when I pulled them, and I suspect they weren’t changed at 210K like they were supposed to. I changed them at 230K so they’ve earned their retirement! Also cleaned the MAF sensor and the (filthy) throttle body.

[@RCarpeDiem83]

Just finished using this video to change the plugs in my ‘13 Legacy. Thanks for the step-by-step instructions! Definitely saved me some $$$ !

[@RCarpeDiem83]

P.S. - Those rear cylinders were a beast!

[@connorxavier4515]

Thank you for taking the time to make such a detailed video. I feel much better equiped to tackle this project now. Will let you know how it goes.

[@jonseifert781]

Best diy video. Paid the dealer for the first change but would have tackled it myself if this video was available 6 years ago. Getting ready to do the second change myself next week. We really need a video on changing the starter on a 2010 outback 3.6r. Mine hangs up when cold and needs cleaned and greased. That bottom nut is the issue. Thanks

[@mikeearls126]

damn what a pain the ass....i dont see myself attempting that

[@armandomontez1004]

What is the reliability of the 3.6r ?

[@coz3757]

Is it the same procedure with an EZ36D in a Tribeca?

[@shralpinist]

TORQUE specs. According to this video torque the plugs to 15.5 Ft-lbs (21 Nm) and the coil bolt to 11.8 Ft-lbs (16 Nm). Hope I saved you from scrolling through the video. Note: I didn't verify these numbers elsewhere.

[@mjpesch]

My Outback is a 2010. Once you've mastered spark plug changing, advance yourself to changing a headlight bulb. Simple? Not with a Subaru! You have to go up through the wheel well and feel your way through it. Big bucks for mechanics on that job.

[@rascaligan8122]

Do I need the engine cover for this? The posts that hold it in place on mine broke and Im unsure if I should get a new one or not.

[@edwardquezada9328]

I have a 2016 Outback and used this video to replace my spark plugs, thank you!Everything went great. However I drove it shortly after I finished and my car was slow to accelerate. Spark plugs are from Subaru and I am not sure what it could be. Please help 😬

[@lizdevaney]

Did you ever find out what the slow acceleration issue was?

[@Jambox91]

At what mileage would you change the coil packs? Do you ever need to change them?

[@MrSubaru1387]

You change them when they fail.

[@awteventqueue]

My fingers hurt already :)

[@alphaomegaambassador4978]

2019 Subaru Outback 3.6R Limited. 60K miles. Job took about 2 1/2 hours. Side bolts for battery tray and the driver's side rear plug were the most challenging part of the job. Total success. Thank you for the video. I saved some bucks doing the work myself.

[@1surfpesca_]

If you’re willing to say, how has your 3.6R limited help up since your original comment ?? I am very interested in finding a 2015-2019 3.6r outback because of the engine and the character of the interior, and I found a great on CPO at 25k miles good service record, I’ve heard both sides of the story. These are either amazing and reliable as long as you take care of them, and I’ve heard stories of this generation having the transmisión lock on them, or engine is leaking at 60-70k miles. Granted I hear more good stories than not so I’m not too scared, but just curious how yours has held up?? If you respond thanks :) if not no worries ❤

[@alphaomegaambassador4978]

@@1surfpesca_ I owned a 2002 and 2013 Outback. My 2019 is by far the best version I've owned. Been and is 100% reliable.

[@akaJackLugar]

If you completed both sides in 2.5 hours you are a stud! Takes me twice that long.

[@scottmccracken8177]

I just pulled the first plug on the passenger side (2010 OB 3.6R) and its has a fair amount of oil on it. Any ideas on what may be wrong? Gaskets, PCV,...? I haven’t experienced any misfires. It seems to run very smoothly. 83k miles.

[@MrSubaru1387]

Most likely spark plug tube seals. Means time for rocker cover gasket replacement.

[@scottmccracken8177]

MrSubaru1387 Thanks:/

[@MrSubaru1387]

Sorry man. :/

[@jeffreywettig5302]

This helped, but good lord, it took me 5 hours and dropped two small extensions that disappeared somewhere, which made the last battery side back on near impossible to get out and in, and that coil, lawwd........ There's apparently one way in and twist just right to get that one in and out.......... Yikes........

[@MegaWetbrain]

How's about undoing engine mounts jacking up engine I saw it in another video any precautions about where exactly to jack under the engine

[@MrSubaru1387]

Completely unnecessary.

[@randywilliams4325]

Just did the plugs at 100k miles on wife’s 2012 Outback 3.6r.I drove the car up on ramps.Removed the the center splash shield.Replaced the plugs from underneath on a creeper.But I am lazy and have a cushy creeper.

[@Spacecadet0730]

Can you get to all 6 from under there by just removing the guard? My wife has the exact same car and I was contemplating doing this myself or taking it to the dealer.

[@MrSubaru1387]

It's far easier to replace the plugs topside.

[@randywilliams4325]

Spacecadet you are going to get different opinions on doing it from the top or the bottem.The car likes to climb the ramps because of the all wheel drive.Its easier on my bad back to lay on my creeper.I cut a piece of 3/8 fuel line to use to start to plugs with my fingers.You don’t have to touch any parts on top.I would bet the Subaru dealer techs put the car on a rack and do it from the bottem.The only problem is those push pins break that they use to hold all the plastic on .

Hello Mr. Subaru ,, I have a 2012 Subaru Outback 3.6R,, and I need to Change the Spark Plugs ,, I have a very very important Question. On the side where the Battery is located ,, When you got to the BACK SPARK PLUG,,, Did you have A DIFFICULT TIME REMOVING the WIRING HARNESS CLIP ,, in your video it DOES NOT show you actually removing the Wiring Harness Clip.Did you remove it after You loosened the 10mm Bolt on the Coil,, And do you have BIG HANDS as I do…This is The only one that worries me…PLEASE PLEASE REPLY

[@user-yf1oq5nc3r]

When would you recommend changing the coils?

[@MrSubaru1387]

When they fail.

[@user-yf1oq5nc3r]

@@MrSubaru1387 For the EZ36s do you know when they typically fail?

[@MrSubaru1387]

@@user-yf1oq5nc3r currently have 296k miles on all 6 original factory coils in my EZ30D 2002 Outback L.L.Bean. There's no set time or intervals.

[@user-yf1oq5nc3r]

@@MrSubaru1387 I also have an 02 Outback with the EZ30D. 240k miles original coils. I've changed the radiator, alternator, tensioner, pulley, both front CV shafts, fuel pump. Any thing else you would recommend changing? Did you change the waterpump on yours?

[@MrSubaru1387]

I have not. Water pump is a major service. Timing cover removed, timing chains, etc to access. Only replace these when they start to leak/fail.

[@steves2694]

On the Driver's side (USA model) the middle cable and cable nearest the firewall are the same length. I admit I didn't label them before removing them from the old coils. I see at 11:40, the one with green insulation is in the middle. Is that correct?

[@jasontruman1215]

Hopefully they didn’t charge too much for that plug... there is nothing special about it, any auto parts store should have it on the shelf for probably cheaper.

[@juanleal5444]

Is there a certain time that the coils would be replaced?

[@MrSubaru1387]

My oem coils in my 2002 EZ30D are at 286k miles. You don't replace them until they fail, which I've found to be pretty rare.

[@dancassidy7471]

Wow Thank YOU!!

[@aurakodiac7386]

Now that I'm doing this, I realize I am watching a speedrun 🤣

[@judahnanas9772]

At what mileage you would consider changing the spark plugs? My 2017 3.6 as 92k km on it...

[@robsonselzelin]

Do we have to reprogram the radio? If yes, how come?

[@janellebrundage257]

How come there are no videos about knock sensors on 2015 and newer legacy 3.6 engine? everything is done only on the little 4 cyl motors.... its frustrating

[@MrSubaru1387]

You have a knock sensor issue on the 3.6? It's the same as the 2.5 in diagnosis and replacement, just you have two and they're under the intake manifold.

[@8eSix]

I'm attempting this on the 2014 2.5. is the process the same?

[@scottmccracken8177]

Awesome video so far! I’m still watching you do the passenger side. My NGK plugs arrived yesterday. Should I check the gap? If so what spec?

[@MrSubaru1387]

These OE, with the odd ground strap, are pre gapped and non adjustable as far as I know. I believe the spec is 1-1.1mm.

[@scottmccracken8177]

MrSubaru1387 Ahhh...ok. Also, I have a quick jack. If you were doing this at work would you do it from underneath? Sorry for so many questions. You’ve been super helpful!

[@MrSubaru1387]

Nope. At work/in a shop. I'd do it just the same. A lot harder to do from below.
