Koolance blue liquid?

 

What is this liquid, can I just use something else like water to top of?

The 3% by weight which is unidentified, is likely the blue color
added to the fluid.

so can I use the green car coolent?

If some of the water evaporated, you could top it up with distilled
water (my hardware store carries jugs of distilled water, for mixing up with
car antifreeze). Distilled water is good, because it doesn't have a
mineral content like some tap water. Meaning less stuff that can corrode
any parts that are susceptible to corrosion.

If you spilled the coolant (meaning equal quantities of water
and ethylene glycol escaped), then logically you'd want to
replace both of them. I guess the question I would be asking,
is what property of ethylene glycol is indispensible to
computer cooling ? In a car, ethylene glycol raises the
boiling point of the coolant, which means lower operating
pressure in the cooling system for a given temperature. But
you would hope the computer is not about to boil the coolant,
or cause the plumbing to be pressurized. So I don't see what
advantage the 30% ethylene glycol is having. Maybe it kills
bacteria or something ? I don't really know. I suppose
by lowering the partial pressure of water vapor, it could
be reducing the rate of evaporation.

 A secondary property of ethylene glycol in an automobile cooling
system is to lubricate the water pump.
