I have only flushed it with fresh water.
I am really starting to lean toward the radiator,
I can not confirm the problem was there before the radiator was replaced.
Because as listed in first post, the car sprang a leak (I dont know how long it had been leaking for - so not sure if damage was done at this point in time - I mean any damage), I repaired teh water leak, filled with coolant and found water leaks at both radiator top tank (split in tank) and water pump (failed seal - water coming from drain hole at bottom), I priced replacing top tank and replaceing radiator - price difference was less that $200 so I replaced radiator - replaced water pump, timing belt and crank/cam seals at same time.
Filled with coolant, confirmed no leaks, adjusted timing and went for a drive - temp crept up as speed increased (this is the first time I can confirm this happening) So I am now thinking that it is possable that the radiator does not flow enough, the radiator shop is taking the top tank of tomorrow for me, and I will have a look in there.

The radiator guy says he can not look at mine till tomorrow, so I might araldite the split, stick it in and test.
