[s-cars] Gelling coolant

[Gísli Óttarsson]

Calgon?  I have not seen this particular brand, locally.  Will something
else do the trick?  Finish? http://www.finish.co.uk/faq.shtml

Then, what is the drill?  Do I just add a bunch to the expansion tank?   How
much?  A tablespoon?  A cup?  Dissolve in water, I presume (Finish is a
powder)?  How long do I run this?  1 day?

Thanks

  Gisli
