I almost went out and bought some rad weld
My Radiator is a skanky rusty old piece of kit and it's started drooling every now and again (understandable given the sound of the engine - I drool every time too!).
My cooling system was in a bad state before my engine conversion with rust coloured gunk all throughout, so the clean that it got may have dislodged some nasty gunk which was actually acting as a clot. Which is why I was worried about radweld - worried that it would actually block my cooling system and restrict it!
I had look into the expansion tank pipes last weekend and they were filthy! I'd never looked at them before properly, but if you extract the pipe from the expanion tank there's a little plastic filter - this and half of the tubing was actually clogged with the ole' gunk (which I'm wondering if it is lying in the bottom of the expansion tank and being sucked through). So I've cleaned them out and am keeping an eye on them.
I think a new radiator is in order though for good measure :idea: I wanted a new radiator anyway even before I knew it was leaking as it looks awful being all rusty like that!
I'm going to go out today and try to work out where I'm leaking from as it's not a steady trickle like you've said you have, mine is more intermittent.
Do you get "performance" radiators? i.e. smaller, lighter, more efficient?
