Tommy/John,
 
    Why are you guys using "tap=20 water"...?  Shouldn't you be using distilled water in an aluminum = block and=20 aluminum heat exchanger...?
 
    Personally, I wouldn't even use tap water in my=20 car.  I've read that any mineral content in the water gets plated = out on=20 the interior walls of the system.  At the least, this will reduce = the=20 system's ability to transfer heat.  If sulfur is present in = the 'tap'=20 water, it'll actually attack the aluminum parts.
 
    I think tap water is a very bad idea...  = Am I=20 nutz...?
