Hi all
I removed the Radiator and fitted out a 5 Gallon drum with some 1 1/2 pipe fittings and bought a yard of radiator hose and plumbed it up to the engine, ran it up and was amazed at the amount of rust and c*£p that came out of the engine, have run radiator cleaner through the engine and flushed it out completely. There was no air in the system when I ran it up with the barrel, but the radiator was full of what looked like fine sand and muddy sediment, so have taken it to be re-cored, at least I know the engine is OK. Thanks for the heads up on the radiator Chris.

Regards

Richard
