Exclamation HELP! Need part number for upper expansion tank hose

Hey guys, I have a 2002 wrx.


The hose coming out of the coolant expansion tank is leaking and I have to fix this soon to get home for my dad's birthday this week. (6hr drive)



The specific hose is the one that comes out of the bottom of the expansion tank and points toward the driver's side before going down to a spot on the engine.


I believe I will need a 10mm ratchet/wrench to remove the expansion tank to get the hose replaced, but I am not entirely sure.


I am planning on getting a spill-less funnel for burping the system once I get it back together.


Does anyone know the part number for the hose that I need?

Are you talking about the hose that runs from the turbo expansion tank above the turbo down to the turbocharger?
If your answer is "yes" then that is not the correct hose you need

All of that is on the passenger side.

Here is a link to a part diagram. https://parts.subaru.com/showAssembl...modelYear=2002

Which part are you looking for?

I'm 99% sure this is what you're talking about. It's the only hose that connects to the bottom of the coolant expansion tank and makes a 90 degree downward between the intake manifold runners connecting to a black metal pipe.

You'll need a 12mm socket to remove the expansion tank from the manifold.
