Coolant - Green Turning Red?

[mcfly94]

argh this all seems to complicated
4.5l concentrate nulon red, rest de-mineralised water, and done, if you have a clean overflow you get the jist of the mix by colour, i fill a 1l off coolant, 1l off de-mineralised water, have never flushed it, just replaced the radiator instead because it was leaking!

Is there a vacuum/suction device that you can purchase to remove all the coolant ?.

I don't believe it possible for coolant to be circulating through the motor for a year and for the two different colours not to mix but to stay separated, that's like mixing half of tin of green paint and half tin of red and not expecting them to change colour unless ones oil paint and the other water paint.

There's a 'coolant flush gun' that connects to the top hose with a water and air inlet fitting (thermostat out). You drain the existing coolant as best you can, then using the gun fill the system with water, followed by blasting the air into the system, forcing the water back out. Alternating between the water and air flushes it out quicker than the fill/drain method.

Thank’s for that mate.
