Simplifying The Coolant System?

[brainbug007]

Having got my engine bolted in now I wanted to start getting my coolant system roughly setup and I've already run into trouble as I've realized that I'm going to have to modify it heavily as I'm using a 1.8 CVH but planning to run bike carbs on it. Can someone confirm I've got where the hoses go right in the attached picture? Also..

1) in the attached picture, I can't figure out where hose 6 is supposed to go? It comes of the thermostat.

2) The donor sierra radiator had an inlet on the top left of the radiator which a big hose connected to from the thermostat. I've got a small radiator from a polo but it doesn't have this 3rd inlet, only an inlet on the top of the right side and the outlet on the bottom right side. So how do I get around this as currently a hose from the expansion tank would go to the top right inlet on the radiator?

3) Does the coolant once it's passed through the block & head come out of the hole at the back of head by cylinder 4 and into the inlet manifold there to be taken through the bottom of the manifold to the thermostat? If so do I just try to relocate my thermostat to this hole somehow because of using bike carbs? Any pictures of how anyone else has done this would be good!

4) Am I right in thinking that hose 2 in the attached picture which comes off hose 1 via a T piece goes off to the heater which in theory I don't need anymore?

5) Quite a few of these hoses that came off the donor aren't going to be long enough now to reach, anyone able to suggest a good cheap place to get new ones? Eg is there a good car to take long fat hoses off from the breakers that will fit ok?

Thanks!
