By the looks of thing my Zeds previous owners couldn't agree on whether to use blue or pink, so now I have a bit of rust and brown stuff in mine.

 

Whats the best way to flush the whole lot out and start again?

 

Would taking off the water pipe hoses be the best and easiest to get to, as I need to take these off anyway to fit some silicon hoses anyway?

well that would be a yes then.... you could also flush it out with a hose after they're off... :)

thats what I plan on doing

 

Thax bud

there is a block drain behind the A/C compressor on the engine, you would be better off trying to get something on that to empty the engine rather than removing the lower water pipe, as that will leak coolant over your crank pulley

 

flush the system, just remember to flush the heater matrix as well as that will also contain coolant
