    no, all it will do is block up waterways in the engine and furr up the cooling system in general. If your radiator has a hole, get a new one

    As above. Broken radiator needs replacing. Everything else is a f**kin' bodge.

    The "Stop Leak" isn't a bodge like K-seal as it doesn't clog up your coolant pipes and gallery's. It stays liquid and reacts to air but it is only to be considered a temporary solution to a problem. Really you should replace the radiator and thoroughly flush the coolant system afterwards.

    Used this on a mate 2003 megane 1.4 16v, still hasnt sprung another leak or caused any problems, put it in over 2 years ago as the radiator was pissing out.

    Re: radiator stop leak?

    well i put a bottle of wynns stop leak in this am, its just looks like a clear liquid, anyway made sure engine was hot etc and put it in,

    at first it just sat on top of the water but after five mins it was sucked through the system smoke started coming from where the leak was and it plugged the leak perfect,

    it has mixed with the water and you would never know it was in there and i have been to London and back today so 300 odd miles and it has not skipped a beat or lost any water!!!!

    so that should hold it until payday when i can afford a new rad.

    p.s just been out to the car and there is no patch of water on the floor like there has been for the past few days!!

    so well recommended.
