I know there have been a number of threads on here regarding engine coolants. Living in a warm weather climate I'm leaning toward running just distilled water and some type of corrosion inhibitor (no anti-freeze).
In looking for the corrosion inhibator I came accross a product called Nalcool 2000. It is a a deisel engine corrosion inhibitor (below is a link to the product data). If anyone is familiar with this product I would be interested in hearing your thoughts on running it in my cast iron FE.
