I have been using this stuff for years even on other Brands I think it’s really worth doing every service to prevent carbon build up.
Click the link in the description to check out a can of engine cleaner.
Bro taking off the throttle body hose as per the actual maintenance steps is easier than what you did. It just requires having the engine clean tool, but this can costs more than the regular cleaner itself, so getting a tool is just a small investment long term over buying this.
The proper way to do this is buying SOA868V9341 and the tool and letting it suck in cleaner slowly for 30 minutes or more.
Don't spray this on rusted bolts, use PB Blaster. You are spending too much using engine cleaner for surface rust.
This spray is fairly cheap now
Especially non genuine versions
I use it on everything.
Iv honestly never heard of the tool your speaking about, but would love to see it in action.
All other videos were to apply the spray while idling at 2-3k rpms. Any reason you spray and then let it sit before starting up the engine again? I know you warmed it up before applying and that is a must. thanks!
Great question, by spraying it in and letting it sit for 10 mins or so if gives the chemical a chance to loosen the carbon and break it down causing it to go through the engine and get burned up.
Also this particular model doesn’t have the small vacuum line on the manifold which allows you to Spray it in while it’s running. Just be careful not to let the nozzle of the spray to not get sucked into the engine which can happen.
The can will have the instructions written on it which does advise you to carry out both procedures if possible.
Hope this helps
Hi mate top video just wanted to ask I have a Nissan patrol y62 you mentioned not to spray directly into the throttle body do I just use the vacuum lines on either side?
@@adamsurf76 to be honest iv never done one on a Y62, but the older Nissans with a fly by wire throttle if you done a throttle body clean you’ll then have to recalibrate the throttle with a scan tool.
But if your just spraying through the vacuum lines for a manifold clean you should be fine.
When cars have heavy buildup you actually want it to sit to take effect if you do it before every oil change as a maintenance you don't necessarily have to do it this way. Many Volkswagens the cleaners don't work well unless you let them sit on top of the valve first
Thanks for this. How long will a can last? 2 or 3 services? Cheers
You can use half a can each time.
So 2 services out of a can.
I've got a 2008 Tribeca that needs an upper engine clean. Would you know where to insert the straw on my car?
Cheers man
Any accessible vacuum line or hose that goes into the inlet manifold.
If not take the inlet pipe off and spray it straight into the throttle
Do the cleaner and an expiry date? cause I have a can that’s over 5 years old
@@Bluehawkeye I’m not sure to be honest
Iv never kept one that long.
I guess it should say on the can if there is an expiration date.
Good video ! At what mileage should this be performed?
Thank you 🙏
Subaru recommends this to be done at every service.
So once or twice a year.
I have a question if you're available
Thank you for this video. Is this process the same for a 2009 Subaru Impreza?
No problem, yes it’s the same thing.
Your engine will either be the same or very similar.
@@Themastermechanic-s3u I was looking at the engine you were working on, looks very similar.
Don’t you do the upper engine clean before the oil change?
It honestly doesn’t matter that much
Everything it breaks down will mostly get burned up in the combustion and out the exhaust.
Great video mate. Where do you get the product from?
For The genuine Subaru spray you have to go to a Subaru dealer.
But there are aftermarket options just as good available online or at most auto parts stores.
Thanks
Ah man typical Subaru boxer engines known for rats living in em.. I spot that rat shit sitting between the intake manifold 😂 I always give my engine bay a good clean out before I take it to any mechanic
Does the car need to be turned on?
Yes
first step : close the hood an do something else. waste of time
All Subaru needs a lot of maintenance unfortunately. Not Toyota...not Honda....only Subaru lmao. I'm glad I sold my FA20DIT WRX.
That may be true, but a WRX is a lot more fun to drive!!
Hahah meanwhile I’m laughing in my flat 6 😆 320,000ks n counting. Just be easy on the hard driving and you’ll be right.. too many Italian tune ups will destroy most cars 🤣
LOL. You’re misinformed Lmao
I have all 3 and Subaru maintenance and repairs are more involved, time consuming. 2006 sti 153,too miles, 1995 Honda odyssey 415,000, 1999 Toyota rav4 246,000, 1998 Honda prelude 225,000
@@PeterHernandez-lg2eh you can't compare an sti to a rav4 lol ns its gonna be more involved
Waste of money and time
It’s really not, I have used this spray on many cars.
It’s also really good at breaking down rust.
Says the guy with carbon coated pistons and all the knocking and consequent retarded ignition timing (emphasis on retarded).
How so?
Imagine spraying this on a hot oven pan with burnt food on it. You think the carbon will come off? No chance.
Take your throttle body off and see inside past the butterfly... always dirty
@@Krooker85 spray it on rusted bolts or brake discs as in the video and leave it for a few minutes.
It’s great at braking down rust.
