Correct me please if I'm being thick but I notice on my tintops (both Zetecs) that the hose coming off the thermostat goes to the top hose on the rad and the pump is fed from the bottom hose. Yours appears to be the other way round.

the pump draws water from the block, and pushes it through 2 external pipes in the vee between the heads to the rear water rail where it flows back into the rear of the heads and round again. The rail also has 2 ports for the donor's heater matrix. The return from the matrix was a Y-pipe witht he expansion bottle on one end, I have attached the expansion bottle directly to this port and blanked the other.
At the front, the pipes from the pump are arranged as per the donor, with the thermostat side going to the bottom of the rad.
