Hi guys,
The distilled water IS NOT more corrosive than tap water; deionized water
IS, however.
If you use Redline, mix a little antifreeze into it. It does degrade the
water wetter a little, but raises the boiling point of the fluid; a point to
remember when you are running a non-pressure system.
To get rid of corrosion (a major cause of overheating), employ a
zinc-magnesium anode in the cooling system (available from your old friend
JC Whitney for 9 bucks) and a Gano cooling system filter (forgot the price).
Flush the system thoroughly, install the Gano and anode, fill with fluid,
and you're off! And no more corrosion. Remember to clean the Gano
frequently at first, since the thing will trap a lot of crud.
Safety Fast!
