Update on my coolant leak. It will need a new radiator as there was a small leak from it. However, the main cause of the incontinence was a hose that parted company from the system as the retaining strap (a spring clip) gave way. It (& others) will be replaced by better quality retaining bands (jubilee clips?) Is this is typical of Morgan using cheap components. If so, silly really as that is not cost effective.
