In reply to a message from cadjag sent Sat 6 Dec 2008:
50/50 is the preferred, I know.
But my point is, I wonder if I would get better cooling efficiency
with something less than the maximum - minus 34F protection?
There’s always some fluid left inside my system after a flush, it’s
just impossible to completely drain it IMO. That said, the 2
gallons of pure antifreeze which I always dump in there first might
be too much - by the time I top it off with water?? In other words,
I don’t remember ever being able to get 2 gallons of water in there
after pouring in the 2 gallons of antifreeze. Yet the capacity is
listed as 4 gallons IIRC.
Yours for better cooling!
Can’t beat heaps of cool, man…
Glycol in itself is not a very effective corrosion inhibitor, which is
why anti-corrosive agents are added. The primary function of glycol is
frost protection, and is separate from corrosion protection. But a
specific amount of glycol, as bought, only contains so much inhibitors
and diluting it below say 30% is considered as corrosion
counterproductive - irrespective of climate. Ie, it is not so much the
less glycol but the excessive amount of water that is the point…
As Craig states; typically the inhibiting qualities of the additives
detoriorates over time/use, which is why regular coolant change is
recommended - irrespective of still correct glycol mix readings.
Now, in principle, where there is no frost pure water can be used -
provided correct inhibitors are added. However, exactly what is then
required is not generally publicised - while glycol data are…
So, while pure water may cool more effectivel I’m not too sure if 30%
glycol will make more than a marginal difference…?
