Coolant is one of the things that often gets over looked on a "full service". Sometimes you have to specifically ask for it to be changed. The Fazer has the fill point for the system under the tank so to check the condition of the fluid you have to move the fuel tank out of the way and I guess the mechanics didn't do that. If you leave it go too long it'll lose it's effectiveness at stopping corrosion and you'll get corrosion from the inside out like you said and when you do change it it'll come out looking like rusty water. If you have a look on ebay and type in "fazer 600 cooling" and you should find some good used pipes
