FINALLY, a subaru guy, a car guy that knows what he is doing, not full of BS and is not so impressed with the sound of his own voice. My hats off to you brother. Gotta love the subies!!! Got 3 of em myself. And you clearly know EXACTLY what you are doing. I wish there were more how to videos on you tube that featured the clear video, no talking material like you post here. Color me subscribed. :)

[@MrSubaru1387]

+thomas womack awesome, welcome to the channel. Glad you enjoy my videos. 👍

[@determineddad7935]

thomas womack heck yeah. I'm relatively new to Subaru. Love them! This guys channel has helped me so much!

[@g-funk484]

has all the tools but throttlebody cleaner spray haha

[@philhall5609]

I second that great video!!!!! Using the right tools and knows what he is doing.

[@Rico24337]

Why you don't have millions of subs yet absolutely BAFFLES me

[@MrSubaru1387]

+Gavin Whiteley idk.. Haha. If that could go ahead and happen I'd be pretty dang happy though!

[@Rico24337]

It'd be awesome! I've done all my own maintenance and repairs on my 2011 Impreza just from watching your videos. They're very descriptive and well recorded. I just find it odd there's not a bigger following here, seeing as you're one of, if not THE only KZbinr who goes over everything with these cars.

[@MrSubaru1387]

Glad to hear that you find my videos useful. 👍

[@joelstevenson1018]

Doesn’t seem like people work on their cars much these days.

[@nicholasmcdonoough5922]

Subaru should have a scout after you! I just went into a Toyota training facility and there was a board filled with electrical stuff from a their car which was pretty cool to see everything working without being in a car

[@mal798]

Fixed my stalling issue during idle relearn. Idle is much smoother now and acceleration is so buttery too. Thanks.

[@gsabella4]

As a new Subaru owner who enjoys wrenching on his vehicles, I truly appreciate your videos. Super easy to follow, to the point, entertaining. thank you. My 2008 Forester and I give thanks lol

[@MrSubaru1387]

I appreciate that!

[@loreiaco]

​@@MrSubaru1387 One question, Do I need to disconnect the negative pole or the entire battery before cleaning the throttle body or not? Thank you for your precious help especially here in Italy...

[@niccadoodles]

Worked great! I didn't think it would need it since my intake plumbing is all nice and clean on my 04 XT. I was completely wrong! Didn't need to remove throttle body, just held it open and wiped the other side.. I used crc throttle body cleaner and it shredded the gunk.

[@Keys879]

I noticed my idle was jumping +/- 200 on my XT. So i cleaned the intake and ran an idle re-learn as per your videos and it has smoothed out. Acceleration feels a little better to. Thank you so much!

[@GaryBrooks007]

First of All, love your channel and your the only reason my wife talked me into getting her another Outback. Love/hate on this thing, my Toyota's seem to never have issues like this one(2013 Outback 3.6R). The car was surging going up hills in 5 gear with the A/C on, cleaned the throttle body(god it was bad), she says it runs like a champ now. Thanks for such an informative channel!!!

[@loreiaco]

[@jasonp410]

Glad to learn about the 05+ throttle bodies. I noticed my idle seemed a little off in my 07 so i got my crc ready to try this cleaning. Thanks for the clear video guide! 🍻

[@whoknows1631]

Surprised he didnt use any CRC cleaner on it he just wiped it

absolute legend , made very in-depth and easy to understand for beginners trying to save some money

[@pkthtguy587]

Yes dude,thanks I just pulled mine out and turns out the gasket was broken,getting it fixxed now what a life saver :D

[@steverobey4682]

2010 Forester, 218,000 miles. Rough idle, sometimes die at a stop. This procedure gave me back a smooth idle, engine doesn't die at stops. Took maybe 30 minutes. Inside of the throttle plate looked like the bottom of a tar bucket. Probably doesn't help it uses a quart of oil every 500 miles. But it's paid for and reliable.

[@SamwiseOutdoors]

I always do a MAF, throttle body, and IAC clean before smog time. I also feed Simon a can of SeaFoam via the fuel system and one via the intake.

[@aussierestorationsmods2715]

I just got my hands on my first Subaru Forester Gt and your videos are helping me heaps, I owe you so I subscribed!

[@ArcticHawk2003]

Very late to this party! Your video helped me take care of issue with my 2015 Forester! Only wish it was warmer outside...

[@joshwarren9523]

Thanks for this. New to Subaru. Was having trouble starting my 2011 Outback without giving it gas. I kept looking for IACV, but it wasn't until watching that I was able to make sense of it! Thanks!

[@dylancook3703]

Especially in the cold right?

[@philc2780]

thanks very much for this video, i'd never thought that this could be so dirty or that it could cause rough idling, so got a can of squirt and cleaned mine today, wow, the filth! took me about 15 mins total, i left the 'body' in place and that includes cleaning my hands of the same filth that came out. oh, and my BL5 Legacy would like to say hi and thank you too. :D

[@MrSubaru1387]

+Phil C glad to help!

[@iriwan]

Fixed a low idle problem when I turned the air con on. Thanks!

[@kellyradcliff1748]

Can you elaborate on this? My idle is rough when AC is off. Turn AC on and it runs fine.

[@kellyradcliff1748]

Feels like it is going to stall at stop light unless air is ON. Thanks!

[@iriwan]

@@kellyradcliff1748 that's strange.. I had the opposite. In hot weather there seemed to be a shortage of airflow through the throttle body with AC on, so cleaning it made the airflow better.

[@magnumpi3466]

By far the best step by step videos!!

[@MrSubaru1387]

Thank you!

[@boriskarloff9992]

Thanks. I have an EJ251 in my T3 Kombi. It's just started revving high on start up. I'll do this. Thanks.

[@SweatLaserXP]

I think I need to do this. My '09 Legacy started shuddering really badly at stop and idle, and acceleration feels really sluggish. And this happened when the fall weather kicked in in New England. Colder weather brings out the problems with your Subaru. Will get on top of this right away.

[@ShootingSportz]

This will be next on the list! Looking forward to getting the daily running nice and smooth! :)

[@dennisroberts6698]

It's amazing how much Crud gets built up in there !

[@yankins532]

Would love to see what the car sounds like before doing the repairs. Learning to do repairs on my own and those priors really help! Otherwise, love the flow of this.

[@cgross5613]

Thanks for the great video. No nonsense, just good info. You just earned another sub. Keep up the good work 👍👍

[@IgnazSouza]

Nice video, now I just need the guts to do it myself! Thank you

[@joepinehill]

good video. I always do a cleaning of the TB when I change the air filter, spraying and wiping. The 08 is ten years old now, this Spring I'll remove as you show. Using Mobil-1 helps keep the TB clean also I think

[@popsiclesinpurgatory]

Saved my ass again 😂 I wish I could share what I just cleaned up. Happy Birthday btw 🎉

[@monogramadikt5971]

great vid mate, glad you went the extra distance and removed the whole throttle body

[@davidkoons2493]

MrSubaru1387 my daughter just had our 2022 Subaru impreza service at 10,800 miles. Tech suggested throttle body cleaning. The tech uploaded pictures and to me looked like a small amount of varnish on the plate and no carbon build up around the circumference of the plate or body. Is it normal for a dealership to suggest a cleaning at 13 months old and 10,800 mile? Thanks if you respond. 4:56

[@collinmc90]

Well here I am once again MrSubaru. Thank you so much for keeping my baby alive! Honestly my 01 Forester has been one of the most reliable vehicles I've owned and part of that I owe to you for helping me maintain my vehicle properly. ready for an oil change and new fuel filter too. been getting some hesitation when pushing the pedal down fast and taking off from stops so just moving through the suspects, already did spark plugs and wires and still getting it so figure its a fuel supply issue, I don't think the fuel filter has ever been replaced on this car. heck the battery I just changed was 7 years old!

[@seanhoward8025]

Hey, Robert! Just a quick add to the throttle body cleaning video. I had done the throttle body cleaning about 20k miles/a year ago per this video and all of the sudden, when my girlfriend borrowed the car (2011 Outback 2.5), it started to hesitate upon take off...but only when the AC was on. No fault codes or anything. Acted almost like torque converter slippage 😖but I had removed the valve body, replaced the solenoids and replaced ALL of the CVT fluid after having done a thorough fluid swap out (drained/filled/drained after 3k miles/filled again) prior to the Christmas lights coming on, so...🤞🤞🤞 Turned out to be a dirty MAF sensor! Cleaned it and when I inspected the throttle body, pulled the MAP sensor and cleaned that, too. Did the idle relearn procedure (thanks!) and all is good once again. I was really surprised I was getting no codes though. Thought this may help someone.

[@ndagijimana]

Thank you for this information, also as you do the cleaning also always check the air filter. Mine was displaying check engine light and was still hesitating after all the cleanup until i replaced the air filter. This was after diagnosis that reported RICH AIR-FUEL mixture meaning less air much fuel. If it reports LEAN AIR-FUEL mixture, its time to check the fuel filter.

[@josebermeo9042]

I have an 02 forester , similar symptoms but mine feel like the back diff is trying to catch up with the front diff, like my gear gets stuck on high rpm or like if it was stick and I down shifted but once I step on the gas it pulls /jumps forward. I replaced the trans, fluids filters and still same. But I don’t think my year has a maf sensor, I’m going to try the map /tps sensors, clean the throttle body plus add a K&N filter, read some where that helped them

[@Honorthelordjesus]

Thanks for your videos I have learn and save a lot of money thanks again

[@MrSubaru1387]

+Sergio De los santos you're welcome!

[@ConcreteSheep]

Mr Subaru - I'm in limp mode with a very high idle, (the idle drops a bit when I press the brake pedal), idle is normal when I disconnect the accelerator pedal. I have tried changing the pedal but getting the same result. I have also changed the throttle body. Getting codes p1560, p2109, p0607, 2138, 2135

[@Subieej20]

Can I use a spray degreaser for the cleaning? Great video btw going to be cleaning my legacy soon

[@nickmoran1280]

Great video, this worked amazing on my Legacy 2010! Quick question, if anyone is still looking at this thread, what size are the two bolts that hold on the air intake handler? They were missing on my Legacy (bought second-hand). Thank you!

[@Shadowman...]

I think you could also use one of those giant cotton swabs to clean it. Just spray the cleaner on the swab end and agitate.

[@ajriehle7078]

Where did you get the clamp pliers that you used on the throttle body cooling lines?

Thanks for the video! Some suggests that it is not reasonable to open the body forcedly (with finger or any other thing) as you might mess-up the factory calibration on it. Question: Is that true?

[@MrSubaru1387]

It's not. Just don't open it past the normal range.

[@joshuaerickyronst.bernard6390]

Oh my god ....I so appreciate this....my 2006 Subaru Forester cross sport is having idle problems ...did an engine scan we didn't get any code or anything ....it was fine but as we removed the Maf and cleaned it ....it a little smoother but still rough ...my car has 157,900 km on it and I don't have a service history do you think this can rectify it?

[@MrSubaru1387]

+Eric Joseph possibly. Without codes or any direction to go, it couldn't hurt to try, especially if it appears to be dirty.

[@joshuaerickyronst.bernard6390]

Ok i'll give it a try and let you know , i'll take some pictures of the throttle body when I dismount it , also do you have any videos detailing how to get to the spark plugs easily?

[@MrSubaru1387]

+Eric Joseph yes, I do, it's for a turbo, but very similar. m.kzbin.info/www/bejne/gqalXqaLnp1kqrs

[@joshuaerickyronst.bernard6390]

MrSubaru1387 Hey I'm going to check it out tomorrow but my crosssport is the 2.0 l turbocharged ej20 is there any different procedures I'd need to note when doing this?

[@MrSubaru1387]

+Eric Joseph should be the same. Just have to remove your intercooler to get to the throttle body.

[@billdanner7694]

Good video! Thanks! One thing I want to ask… I’ve cleaned TB’s on other vehicles and was informed to never manually push open the flap. This triggers something and the car will need to go through a drive cycle hopefully reading right. What I’ve done is turn the key to on, put a block on the gas pedal to open the flap, then proceed to cleaning. My question is: is it different for Subaru?

[@billdanner7694]

Also…. If you take it off, why move the flap anyway? Again, thank you very much for this video. I’ve subscribed and plan to visit again!

[@brianoshea8226]

Great video as usual, about to do this on a 2010 Forester. I have an Ultrasonic cleaner, any reason I shouldn't use it for the Throttle Body? Thanks!

[@stask85]

thx for the nice video! did this cleaning, as i was working on the engine some time before and saw the throttle boddy totally dirty ... after cleaning the whole thing, i get P2101 errors while engine in running in idle. tho no problem while driving (after reset the error by computer). Any hints on this? i can't believe the throttle body is damaged ...

[@PCProphecy]

What's the name of the sensor or tool that warns you when you're tightening the bolt?

[@ChrisSchwamb]

2014 Outback 2.5 Premium owner here with a question: It has 54k trouble free miles. Dealer just did oil change and recommended throttle body cleaning at $129.95. I declined and said "next time." Is that reasonable? They tried to get me for $69.95 for cabin filter replacement which I did myself for under $20. I am more than a little suspicious.

[@ARSciandra]

I'm surprised you didn't spray clean the electrical contacts before re-assembly

[@selfcarewithashley6801]

Is this process similar for a 2000 subaru legacy?

[@richardsmith4187]

I have a 2020 Impreza and have used Lucas fuel injection/throttle body cleaner with each fill up. I now have 72k on it and the engine runs great with no hesitation and idles fine. As a matter of fact it runs like a scalded dog with awesome power. I asked the Subaru service adviser at my last oil change what he thought and he said, if your using Lucas ... your good and shouldn't have any problems. Your thoughts as I think it's a great product which does what it says ?

[@forensic8385]

Each fill up? That is quite the cost. I have 225,000mi on mine and put nothing in and it is has been fine.

[@robertf4572]

Helpful video as always. I take it you don't recommend simply spraying the TB with cleaner while still attached to the intake?

[@MrSubaru1387]

+Robert Ferraro best to spray on a rag and clean it, lessens the chance of getting cleaner into the electronics.

[@britonmarrett796]

Your engine is very clean. Do you have any videos on how to wash Subaru engines?

[@robmiller366]

Once you cleaned the throttle body, did the idle correct itself or did you have a procedure for relearning?

Do an idle relearn after.

Possibly dumb question. The bolt on the right side tube of the air box is missing on my 04 Impreza. That looks like it could be a vacuum tube or something under it, how important is it that the bolt is there?

can you use carb cleaner to clean it up better or not?

[@bertasingan2597]

question - with an electronic throttle body im reading in the forums that the butterfly plate shouldnt be moved at all. is this accurate? what would happen if i move the butterfly during cleaning?

[@JacanaProductions]

I wonder if a dirty throttle body can lead to a slight hesitation when accelerating - 2002 OB 5speed? I have been trying to track down a problem for the past two year - new plugs, wires, fuel filter, O2 sensor front, idle control valve .... to no avail. And I think it all went tits up when I added a can or royal purple max fuel cleaner to the car, it was never the same after that .... odd :( Basically when one accelerates, backs off the throttle and then accelerates again it hesitates slightly, enough for it to be annoying - we've done 600 mile road trips with the car and of course on the highway it's not really an issue but around town this tractor is a pig to drive.

[@monogramadikt5971]

ive had a few odd jerky accelaration issues in the two years ive had my 2008 outback, its driving me crazy, i have been thinking of running some doctor fuel through the tank thinking there could possibly be some moisture in the fuel lines that cause the odd misfire due to injectors skipping to fire . if thats actually what is occuring ? but adter reading your comment im now a bit paranoid about putting a fuel cleaner through it ? *did you discover the cause of your issue since making this comment ?

[@monogramadikt5971]

[@jons4686]

Thanks for the video! Is the procedure roughly the same for the turbo models? Also would your recommend using a part washer or is that too sketchy with the electronic components of the throttle body?

[@MrSubaru1387]

I'd go the rag, brush, and throttle body cleaner route, wouldn't use the parts washer.

[@neilroy4663]

Do you have any troubleshooting - since after driving my 2016 Subaru outback (~150K) almost 30 miles and parking that the battery appeared to just die. I generally drive the car 30 miles each way to work on weekdays and was driving the car after 3 days of vacation. I was able to start the car back again after wiggling the key a bit in the ignition switch and getting it to crank. But after parking and before attempting to restart the vehicle, the car will not respond to key remote lock door or even unlock door {No key fob battery issue as I could resume using the key remote fob after the car started up}. This had happened very occasionally since 65K miles and I saw a service bulleting regarding the battery issue by Subaru for MY 2016 Outback, however while under extended warranty neither the local authorized dealer - Hodges, nor the Subaru Customer Advocate could guide me properly and this issue remained unresolved since then as it was happening very rarely.

[@thorxahest]

Hi, i know it's good step to cleant it, but in my old mondeo mk3, when I I cleaned it ones, RPM started to "swimming", and noone could repair it, so now i'm sceptic. Even i bought another throttle body, but i didnt help. Now i have H6 and would like to do this cleaning but i'm afraid it comes to the same problem as before Regards.

[@MrSubaru1387]

I've cleaned many of them without having to do an idle relearn. Some do need an idle relearn after cleaning. Can't say which will or won't.

[@reckondragon2130]

Just a question should I disconnect the car battery before cleaning?

[@Ash-zo6so]

Hey man I love your videos, saves me a lot of time and money. I just finished cleaning my throttle body and now the car won’t start, I’m thinking I might have messed up the plate or something while cleaning. Anything I should check before just replacing the throttle body? It was running rough and the TB was absolutely filthy so it needed cleaning bad for sure. Would love to hear what you think as google hasn’t been giving me many straight answers

[@MrSubaru1387]

Disconnect the battery for about 30 seconds. Reconnect battery. Turn the key on for 10 seconds, without cranking it. Now, start it. Should be good. The first 10 seconds of key on after and battery disconnect is when the throttle goes through a diagnostic procedure. It won't start during this.

MrSubaru1387 no luck, I’m gonna run back through and check everything’s plugged in tomorrow. If I end up having to replace it then I’ll be using this video all over again, probably about time to pop a new one in anyways, 190k miles and doesn’t look like anyone ever touched the thing.

I’m gonna try disconnecting the battery and charging it before trying again but if that doesn’t work where should I look next?

Question: Does the throttle body gasket need to be change with the cleaning? Love your channel/videos. I have a 2017 Legacy Sport

[@MrSubaru1387]

Recommended, but normally not required. The o-ring style gasket is pretty forgiving.

[@weaponxa]

Always love the videos man thank you for clear concise info! Quick question, 03 Baja NA 257k on her, recently its been having issues idling (low idle) i pulled and cleaned the IACV and it helped some but now it's having a issue where it stumbles to start unless i hold the pedal down, then after about 2 mins at 2k or so it will idle around 700ish. I haven't had the box off the check the TB but I am sure it's as gunked up as the IACV was. Could that be the issue? Or possibly a bad fuel filter? It drives mostly fine excpet at times at stops it drops to under 500 rpm and nearly stalls. Thanks and sorry for the long question!

[@MrSubaru1387]

+weaponxa id definitely check out the throttle body next. Any CEL or codes active?

[@weaponxa]

Thanks for the quick reply! None at all which is what is making this tricky for me to diagnose. I had used WD40 to clean the IACV which is what i saw in a video could that cause issues? It was stalling at stops before this, usually if i had to stop faster than normal. Thoughts?

[@MrSubaru1387]

+weaponxa I would have used carb/throttle body cleaner. WD-40 shouldn't hurt, I suppose. I'd definitely give the throttle body a cleaning.

[@weaponxa]

+MrSubaru1387 Will do! I'll let ya know how it goes. Thanks again!

[@MrSubaru1387]

+weaponxa you're welcome. 👍

[@blastosist]

I have a sticky throttle and it feels like it is from the spring assembly outside the throttle body, but after cleaning and oil it is still sticky. I am thinking I will need to clean the inside to get a smoother throttle response? Do you have any experience with this? thanks

[@MrDoomzy]

Did you also have to clean the maf sensor or did cleaning the throttle body help with the rough idle?

[@MrSubaru1387]

Just the TB in this case. MAF cleaning can also be helpful.

[@MrDoomzy]

Also so I clean the throttle position sensor? I have an 01 Legacy. Whenever I start it up it idles at like 2k then warms up and goes to 1k and fluctuates...

[@MrSubaru1387]

You mean the IAC? You don't clean a throttle position sensor.

[@luismeza7285]

I have a 05 sti that goes into limp mode every 3 months and throws a Throttle position sensor ‘A’. I clean it like in your video and it’ll run for another 2-3 months. Is that normal for a 05 with the electronic throttle body???

[@nickfromboston]

Hi there I just installed a water return line lifted up engine just enough to get it in it did move a very little to the right but not much! I did disconnect the harnesses from engine block! I cleaned up the throttle body and sprayed the mass air flow sensor now it will not start sounds like when you pulled the fuse for the fuel pump!! It did start before!! I did take it off to clean I didn’t replace anything just cleaned now will not turn over! I might have disconnected something but wouldn’t I get a code? I just got a blue driver but if car doesn’t start I cant read live data!! Can you please try to help narrow this down!? From cleaning would the engine need to be reprogrammed, seeing I unplugged and cleaned it up! I could have missed something but not too sure!! Any advice would be great!!!

[@dalethsorbet6062]

i have the 09 turbo model,what procedure would i need to do?

[@monogramadikt5971]

*is it true that there is no separately replaceable Throttle position sensor for a 2008 Subaru outback and that you will need to replace the whole throttle body if that is an issue ?

[@MrSubaru1387]

Yes.

[@monogramadikt5971]

@@MrSubaru1387 thanks a million mate, i just spent a few hours trying to look up info on it or where i can sorce a new part ? ive been having random jerkyness under acceleration and its driving me insane. try to work my way through the smaller potential reasons it could be happening but there seems to be very little information around relating to it ?

[@Cheech808]

Hi Mr Subaru. I have a 2011 outback. Just to confirm i can open the throttle body with my fingers? I thought it needed to he powerwd and the gas peddle depressed? I cleaned it and its running better now but i was afraid to manually open the leaf.

[@mikman7219]

So you did not move the butterfly plate manually? Pressed the pedal for that?

Hey I have low idle on my Legacy 3.0. When gear is in D or R idles it's under 500 rpm and the car shake a little, it does not shutdown the car, but once I change gear to N or P the rpm rise above 600 and stops shaking additional when gear is in D or R and turns AC or light on shake stops and rpm rieses above 600. Trying to correct the issue I already perform a throttle body cleaning, an injector cleaning, MAF sensor cleaning and the issue remains... I have to say that I start to notice this after I change my alternator, so Subaru check and test my battery, and alternator to see if there were voltage issues, but everything seems to be ok ¿any thoughts that could be the issue and how to solve? Thanks

Will you make a video for cleaning turbo model?

[@nicholasmcdonoough5922]

Hey man my throttle body the harness inside wires was split what could the reason be?

[@chickenricesteak541]

Can’t you use sea foam and funnel it into the blow off valve and clean it that way? Or you actually have to physically clean it.

[@MrSubaru1387]

You have to physically clean it.

I did the idle relearn procedure on my '05 Subaru Legacy. I'm still idling at 2000 RPM. Any suggestions?

[@metalman2242]

try going under your hood and closing the throttle by hand. my 05 92x does the same thing and its the cruise control cable getting stuck.

[@7rfan162]

@@metalman2242 I have an electronic accelerator. There are no cables except the cables which conduct electricity and are attached to the throttle body motor. I don't have cruise control either.

[@enyad7589]

The tools you used to measure the torque as well as all used to hold the clips and unscrew the bolts...where can I get those to buy? And what are their names?

[@MrSubaru1387]

Torque wrench, hose clamp pliers, ratchet and socket. You can find all these tools on my Amazon storefront. www.amazon.com/shop/MrSubaru1387 look under the "Must Have Tools" list.

[@yanushkowalsky1402]

that seems fairly easy... what I am paying my mechanic for!?

[@whoknows1631]

Got a Torque rench?

[@Frankisky]

How often does it need to be done?

[@bikebrotherstrinidadandtob1800]

My impreza thanks you.

[@MrSubaru1387]

+Bike Brothers Trinidad and Tobago you're both welcome. 👍

Hi mr Subaru, Is there any screws to adjust the throttle plate valve to open it manually in drive by wire throttle body?

[@MrSubaru1387]

No. There's no adjustments to be made. PCM controls it.

[@divyanjain9227]

Hey, I opened the throttle of my Subaru Imreza Sport Wagon 2.5 and couldn't see the butterfly valve. Is it placed somewhere else or it there other mechanism used in my model ? Anybody any idea. Thanks !!

[@rapidfirest]

My Forester had on low response acceleration, I cleaned all the components, inside the throttle body and deeper and then the acceleration was fast :) Now I have a B9 Tribeca, but I don't know if I can do it the same process ...

[@MrSubaru1387]

+Ismael Forester process is quite similar on the EZ30 in the Tribeca.

[@rapidfirest]

MrSubaru1387 Thank you,. I did not even know that was the type of engine 😂

[@MrSubaru1387]

+Ismael Forester yea, depending on what year, the Tribeca has an H6 3.0 EZ30D or EZ30R.

[@rapidfirest]

06 B9 Tribeca 3.0

[@MrSubaru1387]

+Ismael Forester 06 should be an EZ30R.
