Should not need frefurbished unless damaged and if it is damaged go for a new one Alloy radiators are never as good after being subjected to torsional stresses etc the allot hardens and is prone to vibration leaks
Whilst it may be a lot of wonga Its significantly less than being recovered somewhere and getting towed in with a possibility of a duff headgasket or worse a head!
Thanks for that, he has already replaced it with a BMW radiator which he sourced from Germany. He seems to think that if he can get it repaired it would be work a good few bucks? Anyway consensus seems to be that he should dump his old one.
