Water bypass tube help

[Aldures]

Hello all,
I got a big surprise today at the supermarket when my coolant started leaking. I had a hard time finding it. I think it is the water bypass tube but the bloody thing is going under the manifold.

The tube looks like it corroded through. Do I have to remove the manifold to get access to this tube or can I simply un-connect both ends and pull it through. The other question is where is the other side of this tube? I couldn't follow where the tube went since it goes under the manifold and I haven't developed xray vision yet.

I don't have much time to fix this right now so I am looking for a quick and dirty way to solve this problem. If I have to cut the tube at both extremities and put a hose in rather then take the manifold out I am all for it. It's winter here and I really don't feel like taking a manifold off unless there is no other choice.

If anyone has any advice I am all ears.

Thanks,
Tim
