Im just running tap water as its not cold enough to freeze the water yet.
Will water boil hotter and cause more pressure as my heat temp thingys goes past half way and the fan come on and then I can hear the water bubbling 
Just I thought antifreeze was just ANIT-FREEZE

my old corsas fan didnt used to come on until the temp read like 100  although i believe anti freeze does keep it slightly cooler. just buy some antifreeze :s its like a quid

Its not really necessary im not putting any antifreeze in at the mo as i have a slight rad leak so would be a waste of money, never heard any bubbling etc though.

it is necessary as water alone will corrode internal parts quickly. coolant has a chemical to prevent corrosion and breaks down the acid.

All de ionised water is, is water that hasnt come into contact with metal. Ie tiled roof, plastic gutter then into plasticwater butt. Perfectly good for batteries.

and not until 120'c in the coolant system as its pressurised.
but use antifreeze type stuff, its not expensive.
