Rugby water is mega ultra hard.

Just lots of soluble mineral deposits around the reservoirs, I think. As a kid I used to get problems in softer water areas cos I was so used to the hard water.

ahh just like when you go on holiday and they tell you not to drink the water

I just changed out my coolant. I used distilled water and Toyota red (non-premixed) anti-freeze. I'm a bit on the cautious side, so I wanted to stick with something that had low silicates, and certainly no 2EHA as used in Dexcool...

You can also use 'de-ionized' water instead of distilled water. Or just use pre-mixed, for the k.i.s.s. factor

Surely if you're changing the colour of the coolant it's important to flush it with water?
