thank you everyone!! been a big help. could still do with a couple of diagrams of the complete cooling system and engine wiring if anyone has anything.

i have a 2WD loom will the L8 ecu fit on to this? if not what ECU do i need?

you mention a bottom turbo water pipe does the turbo have a water feed to it and a return to tank somewhere then also?

sorry to ask silly question but this is the first time i've ever seen one of these engines...

thanks again chris
