As always, standard disclaimer: I am about to recommend the WRONG WAY to
fix your problem. Always fix the problem, don't apply a band-aid.
However....

Have you tried the standard powder (Bars Leak Gold, or something similar)?
That is a good (TEMPORARY!) fix. No need to drain coolant, etc. It will
get you another zero to several thousand miles.

The Sodium Silicate stuff does require draining coolant. If not, you will
kill your engine, no questions asked. I've not tried it, but it has a good
chance of working for zero to several thousand miles. (ZTSTM) YMMV.

Jon (where did that confounded satellite radio thread go?. BTW, you can
get a free(ish) sat radio from Sirius again. You just pay shipping, and
of course, access fee. I'm not stupid, so I don't have financial
interest in Sat. Radio. I actually derive most of my income from
traditional radio, which is (well, now was) scared of sat. radio.)

Now, that my head leaks coolant out at the rubber gasket, I went to the store and read the instructions.  I think, it is only good for conventional engines, but I could be wrong.
