Ferrari Mailing List: Re: Engine Rebuild III

[Martin Stark (MStark]

Danger, danger Will Robinson!  Using pure water for coolant will lead to 
cooling system corrosion.  The organic acids additive package in 
antifreeze provide a degree of corrosion protection and water pump seal 
lubrication.  If a car with a healthy engine and cooling system 
overheats during normal operation then the radiator capacity and/or its 
air flow needs to be increased. There a good ways to accomplish that 
using custom bits, and they're cheap by Ferrari price standards.
