Radiator Coolant vs Plain Water

[Steeljack]

what are the practical advantages of using radiator coolant over plain or distilled water? will using ordinary water easily destroy today's engines?

I remember when I was still a kid (sigh) and we still had our tough Ford Fiera (the first AUV?), everytime we cross the stream before climbing a steep uphill to our farm, my father will just fill a bucket of water from the stream and pour it directly to the radiator...no overheating going up

now pre-packaged commercial coolant is everywhere which we all know is not too environmentally friendly.

Search po dami na po threads about that.

Water cools the engine and commercial coolants protects your radiator from corrosion. If you use a commercial coolant, you also need to mix it with water. A commercial coolant mixed with water also increases the boiling point of water resulting to less pressure build up in the radiator.

BTW, we only use water for our cars' radiator.

MASAMA BA PAG MAY COOLANT?TNX..

sir eurie, hindi po masama. mas masama kapag walang coolant kasi plain tap water could cause corrosion (rust) to the water jackets of the engine block, at mas mababa ang boiling point kesa sa merong coolant (hence, coolant). sure, rust won't hurt the engine, but these deposit could block the passageway eventually, thus resulting to overheating...

And most coolant is already pre-mix with water called 50/50, no need to mix it with water yourself.

Absolutely not! It's just an option you can put in your radiator to prevent rust and corrosion on your radiator and it also increases the boiling point of the water.

Tap water, mineral water, distilled water?

distilled water.

[ghosthunter]

using mineral water (or ground water) might cause eventual "scaling" inside the engine/radiator. This is mineral deposits left behind after the water have evaporated... something like salt left behind after you heat saltwater.
