ano po yung 50/50? if i understood it correctly.....ang coolant (na benta sa gasolinahan or auto supply) ay 100% coolant? (ethylene glycol na yun?)

di po ba: coolant (50%) + water (50%) = 100% liquid poured into the radiator?

Or, mayroon na bang pre-mixed (50+50) na benta ngayon?

IM experience, *50+50 (coolant + water) increases the boiling temp of the radiator water, thereby reducing overheating.

will altering that ratio (like 30% water + 70% coolant) harm the engine? or increase the boiling point? or is it not advisable? is it advisable to do this? is it advisable to use 100% coolant, para mas mataas ang boiling temp?
