Hello all,

Any quick fixes I can do on this small leak? It’s not a major problem as very small amount is lost but would like it fixed. Thinking a solution internally to seal or a putty of some sort to seal it externally.

Heard good and bad stories about radweld so would like advice please.

Thanks
Brad

Tricky - What engine is it? If it's the K series 1.8 then no-one would recommend using a sealing compound like 'K seal... Rad weld...'
It looks like the coolant is tracking along that crimped edge on the plastic side tank - is that correct? You could remove the radiator and pop into a radiator service place and have them look at it, pressure test it and maybe give that crimped edge a squeeze.

They are an aluminium radiator. If it's an old radiator then one of the fins may have become loose OR there could be some damage to a tube. Aluminium radiators are difficult to repair - A replacement radiator isn't that expensive.

TD4, yeah to be fair I could pop it out and try to re crimp it, but would like to seal it as well if I’m putting the effort in to get it out. Thanks

Use k seal it works

But the side effect is it settles in the heater, reducing the heater performance massively.
