RT> alter the manufacturer's suggested proportions will only do harm to
RT> your car.
RT> The second reason is the flip side of the first: pure
RT> antifreeze/coolant doesn't have the heat-transfer abilities that an
RT> antifreeze/coolant-and-water mixture does.

RT> THE NEXT PARAGRAPH IS IMPORTANT=MY EMPHASIS (RT)

RT> In fact, if pure antifreeze/coolant is used in a car's cooling system,
RT> the system LOSES (emphasis mine again) about 35 percent of the

RT> the proper amount of water.
RT>
RT> Pure antifreeze/coolant isn't nearly as efficient at getting the heat

RT> coming) RUNNING ON PURE ANTIFREEZE/COOLANT IS PURE FOLLY, AND WILL ONLY

RT>
RT> The third and final reason to use a mixture is that water must be
RT> mixed with the antifreeze/coolant in order to keep the latter's
RT> performance additives- silicate, phospates and nitrates-suspended.  (My

assistant: An "expert"???  Perhaps this expert was into replacing radiators, heater
cores, and water pumps.  Here is an article from the newspaper, in which
the author is considered to be a pretty good mechanic:
