[QUOTE="RossKean, post: 1383955, member: 19880"] I read that fjrtech article when I first got the bike and I still don't understand why anyone would want to bother to remove every drop of coolant - assuming that you are replacing it with a compatible product. I open the radiator cap, remove the drain bolt on the water pump and refill with 50:50 (after replacing the drain bolt). You can siphon out the expansion tank if you wish. Refill it and call it good until the next time. I change coolant whenever I do a valve check since it has to be drained for that. Note: Antifreeze remains effective forever but corrosion inhibiting additives go off and the fluid picks up some (not much) contamination over time. [/QUOTE]
