WATER

What about water?

Water quality effects the efficiency of coolant additives

When untreated, water is corrosive. Distilled and deionised water is inherently acidic. The very lack of ions make distilled and deionized water unusually corrosive and is one of the most aggressive solvents known.

Water having a high mineral content or corrosive materials is unfit for coolant use. 

Never use water from a Water Softener.

  1. The first issue for automobiles is scale build up from minerals in hard water. With modern inhibitors and propylene glycol this scaling problem is minimised. In order to get scaling at the level that concerns us you have to fully boil the water, and the left residue, over a repeated layer of scales, like a kettle or electric heating elements. This does not happen in sealed circulating systems with propylene glycol which boils at 369F. In 16 years of using propylene glycol coolant my 1932 Rolls-Royce Phantom II has never boiled even over the Alps and Pyrenees.

The second issue for automobile users is what water to use with a coolant concentrate. It is not only what water to use and where to get it, but what water does the coolant manufacturer assume to mix with his product?
