use coolant, thats what it's for. water may have whatever, but it evaporates easy and other stuff i don't know.
but i'm sure other people will elaborate

So which do you run and why? Water is supposedly meant to have a better heat transfer but which is better for an A Series engine? Thanks |

im pretty sure coolant is a corrosion inhibitor and raises the boiling point of the water its mixed with also |

That is what i thought 
All opinions welcomed Matt |

Water has better heat transfer. Coolant has a higher boiling point. (you can run hotter before it boils) Water is not as slippery as coolant on a race track (Penrite make a less slippery coolant) Coolant has a lower freezing point than water. (Water expands when it freezes and if it freezes inside the motor it can push out your core plugs and or crack the engine block) Water will not protect against corrosion. This is the most important thing with a mini. When you have a mixture of aluminum and iron you get nasty corrosion and it will kill the water pump and thermostat housing very quickly, the brown sludge will block up the radiator as well. So you need coolant to run hotter, run colder and protect against corrosion. You need water to? |

Thanks 1100 Thats what I had expected. So the water can be dropped out tomorrow morning and replaced with coolant I had never put water in any of cars only coolant but the guy who we bought the car off had only run water.
Thanks for all the help Matt |

i'll ask my girl freind , she's in her 4th year of bach of science with major in chem, they didnt invent that stuff for nothing, and i know for a fact that water and colant have temp droping differences also as well as the boiling points, at 100 deg cel, water takes a while for it to cool down, coolant on the other hand cools down quicker. this i dont know but i cant see how because coolant is water mixed with something |

COOLANT BY Far and away is better than water all the costs of water vs all the cost's of coolant I use coolant Heat transfers faster with a Higher difference so coolant @ 130 Degrees much better than steam (if you have 130 Deg cooling system you have other problems I would imagine Coolant offfers anti-freeze protection as well as corrosion resistance that water doesn't, and protects engine components from wear. Most importantly a clean coolingsystem will stay clean and encourage good heat exhange with coolant in it where a water system will rust and deposit rust and metal particles in cores of the radiator and other places, trashing your cooling system and costly repairs guys running water please flush your systems out with a radiator cleaner additive and then re-fill with water and rust inhibitor at least. Cooolant preferably |

the first time i put coolant in astro he turned into a kryptonite kettle... emptied him out, stuck water back in and he was fine... |

I put a minimum mix of 60% coolant to 40% water. The only time I've ever had a problem with heat is when I had cracks in my hoses. I've heard lots of pro's and con's. I say use whatever seems to work. I often use a 80-20 mix coolant to water, but like I said if it works for you then do whatever that is. |

not everywhere just foaming into the overflow... 
i suppose a Kryptonite Kappuccino also applies..

just a little note here, the higher the content of coolant the less efficient it is at transferring heat, 25-30% coolant is more than enough any more and the car will run hotter
