Thanks Nick for your input however I feel that failure after 4 years indicates that the radiator was not fit for purpose and not of a quality that a reasonable man would accept given that top price was paid and it was fitted by Morgan I have spoken to qualified motoring professionals who agree with my view. The radiator may have been damaged during fitting and given Aero Racing hard nose they would never admit to the damage.My old BMW which I still see about has had the same radiator for 20 years where would the motor industry be if a manufacturer could not expect a radiator to last more than 4 years.
