[@kostadinustavalkov1902]

@Micah Garrison to be honest no I didn't, I think it wasn't that clogged and nextime I'll do it later not at 30k, my thought is probably my engine is port injection not direct and that's why

[@garetht1236]

2 years later the KZbin algorithm's help me find your video and might I say, thank you for making this video! It was pretty helpful!

[@OverlandPNW]

This made me realize I have some deferred maintenance to get to on my rig ! Excellent video !

[@RoadTravelVlogs]

This is another video which is very helpful. My 2014 Subaru Forester is almost 200000 miles. Thanks again.

[@ryanahrens741]

I was throwing a P0120 CEL code that was very intermittent, but when it got to the point where I had the car stall out at a stoplight, I decided that it needed fixing. I did this, and after the smoke cleared from the Seafoam and manually clearing the CEL, It ran for a couple hours and no issues! Great video, thanks!

[@willmtaylor]

Really appreciate your videos! They’re clear and concise without unnecessary editing. Funny enough, I also have my own bolt, washer, and nut where the broken/missing clip was.

[@marksandstrom4248]

Thanks, a well done video. I do have a caution for everybody, having bought the kit from my local dealer's online sales, and picked it up there - on receipt the Top Engine Cleaner Can had very obviously been leaking inside the cardboard box, which was dark-stained, and the can had only 1/3 of its contests still there. I only discovered this when I brought it home, so I immediately brought just that can back to the dealer parts counter, to find that they don't stock the cleaner alone and would have to order the whole kit and they need the injector cleaner and throttle plate cleaner back too. I negotiated agreement to wait until the new Top Engine can comes; then I'll bring back the Injector and Throttle stuff, instead of making 3 trips there. Still waiting to hear it's in. A nuisance.

[@Dylan-san]

Got kit for about $17 but no leaks here. Sorry to hear that. I’m going to a Subi guy I know instead of the stealership to save some money on top engine cleaner.

[@johnpflug1567]

I never knew about this trio of products from Subaru. Thanks for a great video!

[@MTsubfly]

Thanks John! I think they are pretty good products for a decent price. There are comparable products for sure. Thanks for the kind words! Cheers!

[@Mrsedus91]

Just bought this kit and was trying to figure out how to use it. Great video. Thank you! Now off to get my Impreza running smoothly again :)

[@rickfulton2353]

I have a 2015 Limited 2.5. I choose to remove the TB to clean. Then replaced the $7 gasket. I then did the throttle body relearn sequence to ensure it was perfect. I would not use Seafoam as the chemicals in Seafoam are very different. BG has a product that uses the same agents. LuquidMoli has an oil flush product I am also using at 60k. After analyzing FB engine rebuilds due to oil consumption. These engines appear to get excessive carbon in the oil control rings; hopefully, the top and bottom clean on a regular interval will delay problems. I love your videos.

[@MTsubfly]

Thanks Rick! Carbon on the control rings would make me wonder if lower quality oil is to blame, or blended oil specifically. Maybe full synthetics would help with this? I hope? Lol 😆 Also, I would think that could come from lack of cool down, or excessive city driving?

[@richardnieuw2658]

How did you the relaern buddy? i have a 2012 impreza with an FB20 engine

[@jkxss]

Hey MT, I just did this on my 16 Forester (non-turbo) just now (P0172 fuel mixture too rich error). I watched MrSubaru1987's video as well as yours before doing it. After having done it, I would suggest you remove the throttle body screws (10mm, torque is 5.9 ft-lbs or 8 Nm). You don't have to remove the hoses on the throttle body, but if you put a rag under it, you have easier access to both sides of the throttle body plates when using the throttle plate cleaner (SOA868V9170). I personally removed the air intake as well to clean the MAF filter and inside.

[@MTsubfly]

yea bro I totally hear ya. Everyone says I should have removed the throttle body, and I almost did. Except that you do not have to do that, and many folks do not feel comfortable removing it. I know Mr Suby has his video, and I thought I would show performing the task without removing it. I am completely satisfied with how the process went. But it's good for mechanically inclined individuals to know that the option exists to remove the whole body. Thanks for your comment! Appreciate the feedback! :-)

[@jkxss]

@@MTsubfly If I had to remove the throttle body rubber lines that would have been too much, but I verified the torque spec so easily and it seemed so easy to get a better cleaning result so I went for it. Any maintenance items you have planned for your Forester before the end of the year? Also, it may be better to not remove the throttle body because it says in the service manual to use a new gasket (the wire mesh thing at 3:29). I took out the gasket (16175AA430) and cleaned past the wire mesh thing and reinserted it.

[@bevegangogreen2140]

Great video MT. Thank and much love for sharing all your videos. Because of your wonderful kind effort, I too learn how to do my own maintenance on my 2015 Subaru Forester. Mucha Gracias!

[@PapaE001]

The plastic tab that you replaced with the bolt......is probably sitting in the cover that you remove to do the front diff. gear oil change. At least that's where I found mine. I'm getting ready to clean my '14 throttle body @66k and was hoping someone did a video. Great video! I'll be waiting for new content.

[@MTsubfly]

Lol! I'll check!

[@cr8tvty]

great video - but i'd second the suggestions to remove the throttle body (4 10-ml bolts and a plug - 5 minutes - and you can re-use the flange) or you'll never get it that clean. Someone had tried to do clean it in place on my 2011 outback and all they did was scratch up the surface carbon - probably the dealer. And any vacuum hose will do for the Top Engine Cleaner. Mine never tried to stall, perhaps because i had a helper rev the engine to 2000 while adding it (maybe i just blew it out the tailpipe :) - Don't know yet if it made a difference, but it was occasionally stalling after running great on a long trip and then maneuvering slowly into a parking spot. But it would start right up again. Hope this clears that up. Thanks -

[@ElementofKindness]

My understanding is, the back of the throttle plate being dirty doesn't bear any results on performance. It's the edge of the throttle plate, and where it makes contact with the throat of the throttle body, that makes all the difference between being clean or having *hard* deposits, and only effects idle and very low throttle settings.

[@blakey9089]

Not true, it also cause runaway revving when putting in the clutch on manual 2010 foresters, I recently found out after worrying the clutch was screwed. But nope, manually removed and cleaned throttle body then did idle relearn and the clutch revving issues completely subsided. Subaru's are a different beast as I've been finding out.

[@blakey9089]

You are correct about the edges being the main culprit, however if your cleaning edges it's just as easy to clean the whole plate otherwise it will just come back faster.

[@richardnieuw2658]

Thanks buddy, great work, i want to unbolt the TB , how is the relearn procedure?

[@_kuripot_gaming_3088]

This is awesome man. Thank you. About to do mine this weekend

[@_kuripot_gaming_3088]

@MT i cannot find the kit from my area though. Any other links?

[@gibbleway]

I kept getting some o2 sensor fault bank 1 lean and the 'professional mechanics' were way off kilter wanting to replace a mostly efficient o2 sensor. a kid at the car parts store was like try cleaning the mass airflow sensor on the subaru, and that got rid of the code. long story short, mechanics shops are the new banking system, they will hold all of your money.

[@gibbleway]

appreciate the intro this is going to make it easy, some guys try to take off/apart the whole throttle body housing I like how you didnt and got a good swiveled POV to brush at it attached will try soon need to get some vinyl tubing and clamp

[@dars77mercs]

Thanks for the video bro. Love your work.

[@NickBEADG]

Throttle is very easy to take off and it's a good idea to get a new gasket for it which replaces that screen because that gets super dirty and caked up too.

2015. You might consider doing this at 50k miles, not a big deal, but maintenance is all about prevention.

[@mothers22]

Do you have to change your oil a few days later after doing this treatment?

** Notice ** Subaru is no longer selling this kit. The new kit is PN# TPSFUEL 3 Part Fuel Kit S94004 for $71.79 !!! The kit is no longer Subaru branded and contains the following: Bardahl Pro Fast Clean Fuel System Cleaner - pn# 94040 (11 fl oz) Bardahl Pro Air Intake Cleaner - pn# 93076 (6 fl oz) Bardahl Pro F-I-A-I-C Fuel Induction Air Intake Cleaner - pn# 94060 (11 fl oz) The Louisville, KY dealership offered this Fuel Induction (Carbon) Cleaning service for $199 to be performed / recommended every 30,000 miles

[@MTsubfly]

The local dealers have a ton of these kits, still available at a lot online retailers, but there's capable alternatives to use that are easily available anyway. I've heard they were discontinuing this product years ago, but haven't seen it dissappear, still available so i dont know about that... The dealer can do a much deeper cleaning on the fuel system, im not familiar with it, but that may be what they are charging that much for. Cheers!

I really appreciate these videos. I am terrified of messing with my CVT though. Would you trust the "stealership"?

[@elimogenson3316]

CVT on my 2010 outback began failing after 150k miles. Dealership where the car was purchased certified pre-owned about a year and a half prior wanted a little over $5k to replace it and the torque converter. A local transmission shop did it for about half the price.

[@kostadinustavalkov1902]

For changing the cvt fluid you have to other option, only dealerships have the machine for reprogramming after the change

[@ddb1143]

@@kostadinustavalkov1902 What do you mean by "reprogramming"? Drain the fluid, add fluid, check fluid temp and use the top-off process. There is no programming that I have heard of.

[@kostadinustavalkov1902]

@@ddb1143 that's what I been told, even my mechanic told me he can't do it coz he doesn't have the machine. I'm guessing the dealership didn't do drain and fill only coz it's only 5 qts that way and they charged me for 13 which means they took out all the fluid including what's in the torgue converter ,that's supposed to be how much is in the whole system

Thanks this was a very useful video. Thumbs up

[@emiliog.4432]

I read that the tool atomizes the cleaner. That it’s not good to use just a regular hose. Thanks

[@Ghryst]

you should let it sit after the 2nd application. first to loosen crap up, 2nd to deep clean, 3rd to rinse

[@grandtheftavocado]

I found un-bolting the throttle body is way easier. Also did the idle re-learn procedure.

[@MTsubfly]

Totally a great option for folks looking for a deeper clean/project. I could be done in 6-7 minutes with a rag a brush & the cleaner without removing the whole throttle body.

[@MTsubfly]

I hear ya, focus on the basics first. Air supply, fuel supply,and spark...a typical tune up. Then expand to look at other parts like transmission.

[@jkxss]

Auto-play led me here while I was in another tab, but I am glad to have rediscovered your videos, MT :) will plan on doing this and fuel filter soon.

[@MTsubfly]

Glad to have helped! You can do this!

[@jkxss]

@@MTsubfly I skimmed through the fuel filter video and checked prices on the "pricy gasket" and fuel filter and it was ~$200. As far as this throttle body plate service goes, the link in your description says you need another tool, but that tool has been discontinued apparently. www.subarupartsforyou.com/oem-parts/subaru-engine-maintenance-kit-soa868v9341 "****Application requires SOA868V9431 NOT INCLUDED Top Engine Cleaner Tool" I will ask about it (if there is a newer tool with different item #) when I visit my parts dealership today or tomorrow. I'm at 35,500ish miles right now so I might wait on the fuel filter since I know you said Subaru says 72k miles, and you probably won't have an issue until 100k miles. My 2016 Forester (non-turbo) is 4 years 9 months old, but I am always looking for services I can DIY. I finished up a coolant drain and flush yesterday! If you're interested, I posted pictures and everything. www.subaruforester.org/threads/2016-observations-on-my-first-coolant-drain-and-fill.807385/page-2#post-7689449 P.S. I love the "you can do this" outro on any video on the seejanedrill KZbin channel! kzbin.info Do you have plans for future Forester maintenance videos? Always looking forward to more, but I also realize they take a lot of time and work (took a lot of time taking photos for coolant change so I assume it takes more work for videos)

[@MTsubfly]

@@jkxss great! Thanks for the info. The special tool is not needed for the top end cleaning kit. Watch the video and you will see all you need is a piece of generic tubing. This is a very easy process. Yes there is so much that can be done DIY. I hope to help people accomplish that.

[@MTsubfly]

@@jkxss I'm considering doing the coolant replacement video as I approach 120k miles on the forester. I have filmed other footage for less popular maintenance items such as oil & filter change, and cabin air filter replacement, and air filter. Not sure if its worth the time to edit those videos?

[@jkxss]

@@MTsubfly I was considering doing one long video for the coolant replacement, but when I actually did it, it seemed like pictures would be better since a lot of it is just waiting. Photo album of coolant change is here: imgur.com/a/BapZ8fB You remove the front undercarriage tray (four total 12-mm hex bolts, six total body clips in tire wells) then remove the coolant drain bolt (not difficult to remove unlike the front differential fill plug lol). I actually removed the coolant drain bolt with one hand while recording kzbin.info/www/bejne/apvSkJtrrZeor7s. Let coolant drain (optional: lift rear of car up more than front to get more coolant out), (another optional: add more new super blue coolant to flush more of the "old coolant" out, then let it drain again. Clean out the coolant reservoir (apparently this can be removed without removing the actual radiator fan lol kzbin.info/www/bejne/o17aeoqOfd-VpZY) Fill radiator up with coolant (~1.5 gallons for me even though FSM says capacity is 2 gallons), then do the procedures (MAY NOT BE EXACT, CHECK PHOTO ALBUM FOR FSM PROCEDURE - run engine at 3k rpm 5-6 times, turn off car, repeat, add coolant, run engine at 3k rpm, turn off engine, set temperature to max heat and lowest fan setting and run). Probably not worth time for video on oil and oil filter change (photo of 17 mm oil drain bolt location is good enough). I think the only tip would be to drive the car up to temp (I personally do ~150 degrees F - can tell in the small screen below front windshield if it is in your 3-gauge info thing). Park it, drain oil, then add oil and do the oil filter, replace with new oil drain bolt crush washer, and torque the bolt to 41.7 N-m or 30.8 ft-lbs. Tip for refilling oil I would explicitly mention would be to do it on level ground and start checking dipstick levels around the 4.5 US quart amount so you don't overfill. Space between two dipstick holes (marked L and F) is 1.1 US qt or 1.0 L FSM engine oil replacement: prnt.sc/10nv319 and prnt.sc/10nv3d5 FSM engine oil filter: prnt.sc/10nv5at FSM engine oil specs: prnt.sc/10nv43b (non-turbo and beginning of turbo) and prnt.sc/10nv4mt (turbo) Engine air filter and cabin air filter are so easy to do that it probably doesn't require editing and you can probably do both in one video within a minute assuming you have someone to hold the camera for you (or tripod mount).
