Three years ago I had my 40 year old brass core radiator re-cored because it was blocked. This is what AAA genuine quality guaranteed copper re-core looks after just three years. This is the problem with rebuilds, not the old stuff failing it's the rebuilt crap not lasting as long.
Well I have my receipt with the radiator ready to go for next week when Mr AAA reopens, then we will see what he has to say about their rebuild service quality and guarantee.
Update below all good all fixed AAA came to the party see thread below
