I know that this subject is covered a few times but I thought I would share my own experience so that others may learn.
Doing the usual commute along M4 when plumes of steam were noticed bellowing from the car. The temperature gauge was rising to 90degs but I managed to pull over and switch off just in time to see, what looked like, the entire contents of the engine coolant system empty on to the hard shoulder
Called the RAC via emergency phone, told them exactly what it was, busted radiator, 1 hr later they arrived. The mechanic didn't have more than 1 pint of water in his van. It took him 2 mins to realise that he wasn't going to get me under way with that! another hours wait for the recovery truck, which by the way was an AA truck
and I was on my way home. I used the seemingly controversial Rad Weld to seal the leak enough to get to the garage.
Next day after having several sky high quotes for parts and labour
(ave £280 for the Rad and £250 for fitting )I rang a fella advertising on ebay, ignoring all the advice on the forum about steer clear of ebay sellers, and having discussed the part with the vendor,I bought a new Rad for £110 delivered. It was with me in 2 days identical to alfa part. It was fitted by a local garage for £132 now I am back on the road with my EOR!
RAC were a let down
Rad Weld works but I wouldn't leave in the engine!
Aaron Rads on Ebay are highly recommended
Peak Performance of Llandow have always been fantastic!
Parts and Labour for an Alfa don't need to be bank breaking
Radiators on 3 1/2 year old cars can be sufficiently corroded to have the fins and the matrix disintegrate.
