The pump's ok but the metal pipe is blocked solid between the pump and the expansion tank outlet.
When I pulled the pipe off the pump no water drained from the expansion tank until I undid the cap when it drained back into the motor and out of the pump itself.
With this pipe blocked no water can get through the manifold or the heater core and no water is flowing past the temp sender.
Tomorrow I'll bypass it with some hose and see how I go.
The bad news is that the head may still be cracked as a result. My mechanic told me the best way to check for water getting into the cylinder is to run the engine up to temp, then pull out the plugs and put a cold screwdriver into each plug hole. If there is any water in there condensation will form on the cold screwdriver. I got a wet screwdriver in no1!
I've pressure tested the cooling system with the motor both hot and cold and it holds 10psi no probelms.
No work on the gearbox yet.
