Finally have a '6, Spares or repair car now got an MOT!

had that happen to me fella, on the blue one, it has a small pin hole leak, and like a pro, i used some rad weld, just as i got home, it burst destroying the rad, i think that stuff is only good if you have a fairly new rad that develops a leak..... not a manky old one like what i had

A hole in the system is a hole in the system and filling the cooling system with shitty gunk is a total bodge regardless of how new the radiator is.

It's fine if you're trying to keep an old shitter limping along but on a car you want longevity out of it's a bad idea. Radiators aren't even that much money.
