does anyone know if the anifrezze you buy from the shops is diluted.
I ask this as in the hot climates some bikes as do cars run neat antifrezze purley from a cooling perspective.
i say neat as does this mean they just use the it straight from the container and add no water.
i have at the moment got a 50 50 mix in my bikes but beleive that i could be diluting it more by doing this and infact using it directly from the container would be better as alone it is a better coolant.

anti.freeze should always be diluited,you can get stuff like pro-cool and the like which you can use as is,not diluition.50-50 if fine,even in very hot conditions

It will say on the bottle. Bought some from Tesco the other day and it said ready to use or something like that.
Think that if you buy concentrate it is usually 50/50
Running neat won't really help cooling but you do get additives that cool better like water wetter.

I don't like using ready to use antifreeze. If you flush the whole system through with a hose pipe (every 2 years with standard antifreeze) some water remains in the system and the ready mixed stuff becomes diluted by an unknown factor. On the 4l0 for example after removing the drain bolts the only way to remove all the water is to take off the water pump cover, (I dont like distiurbing hose joints that are not leaking).
With concentrate it doesn't matter how much clean water is left in the system, you just put in 800 mls of concentrate and top up with de-min water (which won't be as much as 800 mls of course), then you know it is 50% as the system capacity is 1.6 litres. Then top up the header tank with a 50-50 mix.

100% water is THE best coolant... barring recent Hi priced esoteric chemicals F1 cars use.
Adding Gycol reduces water's cooling capability :-)
Surfactants (water wetters) help some but you will need instrumention to see a difference on a steet bike.

The problem with using 100% water is that the system is then prone to corrosion especially furring of the aluminium parts. Most of the antifreezes have a corrosion inhibitor in them to prevent this. I usually use a plastic 1 litre measuring jug to mix up 50/50 of antifreeze and distilled water and fill up as required.

It should say on the bottle.... Also, 50/50 as mentioned by Tone is what I'd use.... totally agree this should be used. My car had blocked waterways making the water (or rust sludge!) that was in there block the head up and boil when running! made hoses pop off and burst and also popped the water-pump seal. If anti-freeze was used this wouldnt have been a problem. Note: mixing more anti-freeze (neat for example) can actually make freezing temp lower beleive it or not, its not as effective neat or near neat. stick to the instructions on the bottle  |

i always use procool and be carfull what you use if you use the wrong one it will rot the gaskets in no time

bare is correct,
water cools better than a water-antifreeze mix, but you don't use just water due to it causing corrosion in the engine, and in winter it will freeze.
So antifreeze is added to stop the above problems, not to cool the engine better as the original poster thought.

Just to add to what rd350r just said if running just with water always drain the water out of the bike in winter when the bike is put away. My brother in law races 3 different bikes and as soon as the season is over he religiously drains all the water out and then fills back up with antifreeze/water mix. Then come race time drains out and puts back in just water - not allowed to run antifreeze in race bikes as slippery if leaks on track. Rich.

Are there any rules preventing the use of antifreeze for track days etc ? |

Hi Arrow, not as far as i know but have not done a track day myself but considering how many people are doing them on road registered bikes i doubt very much they are running without antifreeze. Same scenario with most race bikes have to run with oil catchment tanks.
