Looking for coolant recommendations for Yamaha street bike

[subaron]

I am looking to replace coolant on my Yamaha FZ6 with something decently priced. I read about Engine Ice but it seems for high performance and a can is about $30 before tax for 1.9L and my bike needs 2L and 0.25L on the reservoir. Don't feel like spending $70+ tax on coolant.

I was wondering what coolant you guys are running in your bikes and where you are buying it?

I run whatever cheap stuff canadian tire has on sale.

How bout just running water wetter with distilled water ?

or you could run Engine Ice but top up the rest with distilled.

I love engine ice Great freeze protection, great boil over protection, INSANE heat transfer!! Keeps my bike running WAY cooler than other R6's I ride beside on my group rides! I hear everyones fans whirring away and my temp gauge is only at 86 (fans come on at 102), lol!

Premixed Honda engine coolant for cars...

Prestone pre mix. Canadian Tire and it's what the OEM requires. What makes you think you need something exotic?

Agree.... if your not racing.... go to crappy and get some Prestone. Dont be fooled into spending your hard earned money.

I was on the FZ6 forum to see what others were using and Engine Ice was in the top 3 choices.

I am planning on keeping the bike for a while (esp with all the customization) and was looking to put in something decent...didn't have to be exotic.

Are you running a 50/50 mix of anti-freeze and water? Here's why I ask: Anti-freeze is 10 TIMES heavier than water! If you are running a 50/50 mix, your engine is working 5 times harder just to move the coolant mixture around than if you were running straight water. Of course, water is extremely corrosive, so you cannot run straight water, right? Put only enough anti-freeze in your system that will get it to the lowest temperature you expect it to reach. Add redline 'Water Wetter'. This breaks up the surface tension of the water, making it easier for the engine to move the fluid around. And use distilled water, which does not have the heavy mineral content that tap water does.

The density of ethylene glycol is 1.113 g/cm3, only 11% more than water , which is 1.000 g/cm3 by definition. The VISCOSITY, on the other hand, is much higher. The viscosity of a glycol/water mixture is not a linear relationship, though, and for reasonable mixing ratios it makes little difference to the amount of effort it takes to turn the water pump.

Compared to water, ethylene glycol has higher viscosity, somewhat higher density, about half the heat capacity, but a higher boiling point and lower freezing point.

I am running 50/50 mix (Honda Type II) coolant.

So I should top up the reservoir tank to max with distilled water?

50/50 mix doesn't provide optimum cooling. To improve cooling in hot weather, use less antifreeze and more water, possibly going to a 25/75 or a 20/80 mix ratio. Temperature drops about 3 degrees C are typically obtained by reducing the mix ratio from 50/50 down to 25/75 or to 20/80. The boiling point of pure water is 100C. The 50/50 mixture increases it to 106C. Pure antifreeze has a boiling point of 113C Pressurized systems will raise the boiling point in those cases. At 65% anti freeze mixture you’ve lost 20% of the cooling capacity of the system. Antifreeze prevents corrosion, but even a 10/90 ratio of antifreeze to water will serve the purposes of inhibiting corrosion and adding such additives as water wetter helps. In some states where it never goes below freezing, anti-freeze isn't used at all, just the corrosion inhibitors. You want more water to increase the efficiency of your cooling system, but at least 10% coolant to keep O-rings and the water pump lubricated.
