If the Red Coolant meets the specifications required by you vehicle manufacture you can perform a coolant flush on you system before replacing with the new coolant type.
first of all the difference is in the additives. the red is for heavy loading on the engine and is a longer lasting coolant giving 5 years and 250 000km (this is manufacturer spec) as compared to green coolant which is 2-3 years and 80 000-100 000km so you should in theory save money with the red coolant However if you do change to the green coolant you should always flush your whole coolant system with a radiator flush additive, available from all auto stores, as the red and green coolant do not mix. they counteract each other and can start to solidify and corrode your system.
