[Healeys] FW: Radiator flush

'Interesting,' to say the least.  Tap water is electrically conductive 
due to its dissolved salts (ions); distilled or deionized water has its 
salts--hence its ions--removed so is non-conductive.  Ethylene glycol, 
being an organic compound is not, to my knowledge, conductive.  The main 
reason for using distilled water is to avoid scale buildup from the 
dissolved salts (sometimes called 'boiler scale').

We covered aluminium alloys today in welding class.  There are many 
types of alloys, some of which may not be suitable for radiators (some 
alloys cannot be welded, and can only be mechanically attached; e.g. 
riveted).
