Angry Coolant Leak underneath intake manifold

Hey guys I was on the way to school the other day and i noticed that my hood scoop was smoking. I pulled over and it smelled sweet like coolant. I checked my coolant reservoir and it was low. I know for sure that the coolant is burning on my up pipe as you can see from the video. But the one thing that i noticed is that i can see coolant ontop on the heads on the passenger side. My question is there a mine line under neither the intake manifold? and is there any way to replace it without removing the intake manifold? Thanks

I'm having the same problem as well. Except coolant was all in my engine bay and also in the spot yours is at. My coolant levels were low too soo I filled them up and cleaned everything. Next morning I go to drive my car and the same thing happened. Sprayed all inside my engine bay.

If you have a stock radiator it could be leaking. Mine started leaking a little and I could smell it. Then, I noticed my overflow tank going dry. I looked all over but didn't figure it out till I heard a slurping noise and found the infamous plastic crack. It was almost impossible to see, almost looked like part of the plastic.

Coolant lines on the turbo possibly, check the clamps. There is the big crossover hard pipe that could be leaking, that you would have to remove the intake manifold to replace the o-rings. Check the hose underneath the top little coolant tank, that is right in the area. You could unscrew the tank and move it a little so you get a better view, or even just drain some of the coolant and pull it off.

Most likely just a clamp that got loose.

Had the same problem in roughly the same damn place. Check that line going to the turbo (the one the circle is touching in the pic) first off. But mine was leaking from the throttle body warmer lines. I couldn't find out where the leak was until i took the tmic off. Instead of replacing the cracked line, I just did the coolant bypass mod for the TB.

Looks like its the 90 rubber hose coming from top tank. Might be able to find a 90 hose at a local auto part store, if you don't have a local dealer, and cut to fit.
Had to do that with a hose from Napa cause the nearest dealership couldn't get one for 3-5 days.
O and change the stock spring clamps to hose clamps.

you may alwo want to take a mirror and check under the top seal lip of the upper tank on the manifold. Mine had rust issues like this one... but under the lip between the metal top and the aluminum base.

I think you found my problem! Here is a picture that i saw at that 90 degree bend from the coolant tank. Lucky my local subaru dealership had the part in stock so i replaced it and i havent seen anymore smoke. ***Cross Fingers***

I am going to have to check this on mine. My car started smoking recently and I thought plug seals were to blame. There is what looks to be coolant all over the side of my passenger side valve cover.
