Which hose where

[deezee]

Don't quite follow what you mean by a restrictor at B? That hose at B currently runs straight down to the stub above the water pump. I was thinking of putting a T piece on that hose and plumbing it into C on the header.

How come E has to be connected at the radiator? Couldn't I just connect it anywhere to the top hose?

Edit: my radiator doesn't have a bleed connector on it.
