i bought 5L Nulon Concentrated Coolant: $33 a bitch of a price but i have four cars im not too sure about car companies making auto stuff (eg. Toyota, Honda coolant, engine oil transmission fluid - someone enlighten me on this) so i went with this one also chose the concentrated coz theres: 1:1 option with water for normal conditions or 3:2 for extreme conditions you can vary for crappy side mounted radiators and cast iron blocks one question: can too concentrated be bad for cooling properties of the fluid? |

Yup, the higher the Ethylene Glycol content, the higher the surface tension of the coolant, and the less contact with the metal of the radiator. Sounds dumb, I know. Ethylene Glycol's quality is that it doesnt boil like water and produce steam which can reach phenomonal pressures at times. Water Wetter is a saturating agent, and causes the surface tension of the water to relax, which in turn means more contact with the metal of the radiator, and the passing air(which really cools the engine). Enough Technocrap. If I could get Water Wetter here i'd use it, but I cant so I use 33% Glycol coolant. And yes, I still have overheating problems. I'll see if the bigger carby makes a difference. I reckon the 1 1/4 causes a massive lean out, and gives me all of my drama |

yeh ive been told to increase the fuel conk in summer oh and the guy at the auto store told me a year ago: the more concentrated the better he was also the one who said my 3.4L Prado would take 3.4L of engine oil, and my 998cc mini would take 998cc of engine oil |

this stuff is excellent - expensive, but excellent. My mechanic mate who preps rally cars and all sorts of things gave me a bottle before I took my Cooper S to Winton, ran cooler all day at 6500-7000 rpm than it did driving around town a couple of days before http://www.minimania.com/web/Item/WATER ... Detail.cfm plus it's the oinly coolant you're allowed to use on a race track - not that they check for it on club sprints with road cars |

There he goes, misquoting me again..  
I use Nulon concentrated glycol in mine too, 25%-33% mix. You don't need more. And I change it every 2 years or sooner. Beware of the premixed stuff they sell in stores- some is little more than coloured water. |

Dont bother with the new fangled red coloured stuff, its designed for more modern cars. I dunno what the difference is, but it's specifically recommended that you only use the colour coolant that your car originally came out with. So stick with the ol' green Ethylene Glycol Mix. And I agree with Doc. 33% - 50% is the best everyday mix. The original mini owners handbook recommends a 66% mix, but that was more for the antifreeze qualities in colder climates. |
