    Default Keeping your cool

    Seen in Quentin Willson's article Sunday.

    " If your car is getting hot tempered this summer there is a new product that's claimed to reduce water temperature in your engine by up to 30 deg F. Motor Max Cooling System Additive is a bio-degradable water additive that prevents overheating, maximises air conditioning output and prolongs engine life by increasing waters ability to absorb and transfer heat. It's used extensively by the American racing industry, and both drivers and mechanics claim it really does work. More details on 0845 4583250 "

    May be worth a call !

    Over here it's called "Water Wetter". It was recommended to me by a friend after I was having cooling problems, and yes it does work.

    No. It just keeps things from freezing!

    Sorry Dave but you are wrong I quote from a "Instructor of Chemistry with loads of letters after his name"



    Ethylene Glycol is an organic liquid called anti-freeze which is added to water to make an aqueous solution of Ethylene Glycol and water. This is to prevent water in the radiator of the vehicle from boiling over. It elevates the boiling point of water. At the same time, anti-freeze will depress the freezing point of that same water to prevent freeze up in the winter, hence the name of the solution, "anti-freeze". This ability for a solute to elevate the boiling point and depress the freezing point of the solvent is the focus of this page.



    And he goes on to say that the elevation in the boiling point runs linear to the % mix of the anti-freeze.

    Methinks it also reduces the surface tension of the water which means that there is less boundary layer which means that more of the fluid in the system actually takes the heat away.....



    or does it?

    OK so according to the video, the "Water Wetter" improves the heat transfer from the engine to the water by reducing the surface tension - so wouldn't soap do just as well ???

    Arent you scared of my AS level in Chemistry? (i dont even know the results yet)



    but soap would act as an impurity which would change the boiling point of the liquid as salt does to ice. im quessing as it would essentially make an alkaline solution it would lower the boiling point



    plus it might not agree with the aluminium after a while
