I have - it works about 60% of the time.

If it's a leak out of the water jacket, put product in called Conklin Dyke
in the radiator.

It's sold as a temporary stop leak and I put it in my Mercedes 300SDL
150,000 miles ago. I figured I'd pull the head when it started leaking again
- it doesn't as long as I keep this stuff in the radiator.

And no, I'm not a reseller and I don't believe in "magic fixes". This stuff
just happens to work.

Thanks,

Anyone ever use KW or K&W head and block sealer?

I've got a leaker!
