I have a 2019 Ford Fusion Titanium Hybrid I bought from Enterprise Car Sales last year. Thinking of running CRC GDI IVD cleaner through it. Where's the best way to spray the cleaner into the system? I was thinking of removing the MAF sensor and spray it in through there. I have no idea where the brake booster vacuum line is. =/
How to inject CRC GDI Intake Valve Cleaner in Ford Fusion Hybrid?
- Thread starter hytibilly

Find a vacuum line to tap into, but you shouldn't need to use GDI cleaner in it, the hybrid still uses a 2.0L N/A port injected Mazda-L engine doesn't it?
Correct. I don't need the GDI cleaner but I wanted to do it just because it's used and I want to make the engine as clean as possible and also because I need to mess with my car. I can't find a vacuum line. I even broke out the service manual but couldn't get a good diagram.
I wouldn't do it. What if the intake has valleys where puddles can collect? When you go to drive the vehicle, this can/will result in a hydrolock.
Since it's port injection, just run techron or Redline SI-1 or similar fuel system cleaner before every oil change, since fuel washes the valves there's no real need to run intake induction cleaners.
OK fiiiiiiine. I guess I'll just use the Gumout High Mileage and call it a day.
This is used with the engine on, when there is a vacuum on intake side, no puddles should form.
Yeah, that or Techron, use it for a few consecutive fill-ups if you want to cover your bases.
But, good timing on that purchase, same vehicle is probably $5k more right now.
Yeah, I got very lucky on the purchase. I sold my 2013 FFTiHy for $10,700 to Carvana and bought the 2019 FFTiHy for $18,500 even though the 2013 needed $3,800 in cosmetic repairs. Carvana really messed up on that deal because the second-highest offer was $6,800. I bought it from Enterprise Car Sales, though. I had it checked by a dealer afterwards, and they were surprised. At first, they were mocking me for buying it from ECS but afterwards, they said that it was like new (with 40,000 miles). I spent $1,200 on an extended warranty from Flood Ford that will give me five more years and 60,000 more miles in protection. Probably a waste of money but I really don't want to deal with any problems.
I'll just do Gumout and then Techron just for laughs. Then an oil change. Thanks! =)
EDIT: CarMax willing to buy for $21,500. LMAO.
Look for a hose on the intake manifold - - about 3/8 in size.
Or just open the throttle body and have a partner hold the revs at 2.5k
The CRC will clean better than any in tank can - - - The CRC will also clean your spark plugs and the combustion chamber over the next 7 days after initial use.
Go for a 30min highway drive after letting the engine heat soak for 1 hour.
Set the cruise and go.
I do it 1-2 times a year on each of our vehicles.
On my 2016 Mazda 6 - - puddles do form no matter how you apply it.
I need to drive 1 hour to get all of it out.
If I try and drive above 4k the engine rattles and makes nasty noises.
I contacted CRC and they are aware that this can happen on certain intake manifolds.
No big deal though - - drive on highway to get it all out - - drive it normally - - I can't do any full throttle runs on the mazda for the first hour.
On our Hyundai it takes 10 mins to get it all out - then WOT the carbon away.

those mazdas have intake manifolds that hold quite a bit of liquid in the bottom, just drive gently for the first little while. the intake manifold is shaped almost like a jug, with the throttle body on the side and the runners coming out the top. i poured a cup of oil out of one once. this was on a 2007 mazda 3 so ymmv
and holds the rpm around 1500-2000.
It won't hydro lock.....just get really passed off.
My mazda 6 had a bunch of areas where it would pool.
No amount of revving would get it out until on the road.
Oh it will. Some engines will ingest a large quantity once you get on the road, and bad things will happen.

I use about a fifth of a can each oil change and that might be why I haven't had the misfortune that you speak of. I think consistent application trump's the amount used. Using mine for mostly highway application I'm sure it's not too bad. I have used the gumout multitune as a oil flush and a pea fuel system cleaner.

No it won't.
Hydrolock occurs when a incompressable liquid enters the chamber at a specific volume relative to its capacity.
Crc is a compressible and ignitable liquid.
Water is not.
Crc could potentially do some damage but not hydro lock.....
At least by definition.
