Assuming there IS silicon based life there in the universe, what would they use as "water" or as their organic solvent?

If water is available, there's not much reason to believe they wouldn't use it - carbon and silicon have near enough identical chemistry with water.

Otherwise, your options are quite limited. If it's too hot for water, you're really too hot for most simple liquids - you also don't really expect silicon at high temperatures, as its bonds are weaker than those of carbon, so it would run the risk of breaking apart. If it's too cold for water, you could possibly use some of the simple hydrocarbons (methane, ethane) if they were around in suitable quantities.
