Need help identifying coolant/breather hose

[chrisracer79]

Hey everyone, I am swapping an M20 into my '73 2002 and I'm in the process of mocking up the cooling system and I noticed that on my E30 expansion tank there are 2 small ports for hoses coming off near the filler cap. One goes to the radiator (breather?), but I'm not sure where hose #6 connects to in the diagram below.




thanks

#6 is the overflow hose. It doesn't actually connect to anything.

Well that makes life easy for me. Thanks.

What MR325 said... just make sure you route it so it doesn't get in the way of anything or get melted on the exhaust manifold. There's a handy hole in the frame you can stick it into. That's where mine has always been.
