The top takeoff point is between the top collector where the pressure cap
sits, and the #2 cylinder head (left front cylinder).
A t piece goes in there and a pipe goes to the left hand heater. Then from
the left hand heater to the right hand heater, and then from the right hand
heater to a t-piece put into the pipe from the bottom of the engine that
goes to the radiator.
I think you need a "head" of water in the heating circuit otherwise you may
end up with an airlock.
NOT in the expansion pipe between the top collector and the overflow bottle.
That would be crazy !
Best to RTFM ! (read the flipping manual !) AND follow them !
