You can try any one of the stop leaks you can find. Bars leak is probably one of the better ones. It will likely not last long!!

As we get into the extreme temp difference season we see a lot more coolant leaks. It is likely it will continue to get worse even with a stop leak product.

Your best bet is to replace it and not have to worry about it in the middle of winter if it goes that long. It wouldn't be a bad idea to flush the coolant at the same time especial if you are still running with the dexcool. Once the dexcool starts getting low it seems to deteriate fast!!

We have not had any problems flushing/converting over to the green stuff. Its much less as far as cost!!

I agree with airjer, replace it, as it cools more the rubber seal in it will only shrink more, and it will be worse. Fix it before it leaves you stranded or does damage to your engine by over heating.

Stop leak can work and has in the past, but like said with the extreme temps differences in very cold weather (Cool down in below 0 temps and 190deg once the eng. is started), things flex and leak again with ay temp repair.

You can drain it and use epoxy to fix, but it still is a ticking bomb waiting to blow or leak again.

If it right at a crimp, you can try to tighten with pliers, but be warned this could lead into a much larger leak.

Replace and flush is what I would be doing.

Good luck
