    Most of the time you don't need to drain and change, but there are times when the engine needs to be serviced completely and drained everything in it.

    Sure, it needs to be done so becasue it s one of one of the necessary components in a car.There will be some chemical reaction when it is being used for a long period of time.It will become acidic in the end.To my mind, I knew that almost all the liquid will become acidic in the end,especially those industrial chemical liquid.There is carbon dioxide everywhere in this world.This will make most of the liquid acidic in the end.

    it also picks up contaminants so instead of being neon intense it become s dull greyish green to almost brown with time the radiator and Heater core will suffer from clogging and goop build up so checking the makers suggestion is always best

    It's the lubricant for the water pump, replace via manual instructions.

    Long story short: yes, but it can just be topped off with new coolant every so often every couple months for about 2 years. Eventually, though, it WILL have to be drained completely..

    Does anyone ever get it all out when changing it is the question? When you see the time given no is ever going to get all the old coolant out.

    Yes....every 3 years. Coolant becomes acidic and will damage the parts that are aluminum such as the intake manifold, radiator and heater core.
