i run it , my bike has never overheated since i swapped over .

some one else will recommend something better though , there is always something better .

i have had good experiences with it though .

don't use automotive coolant , if it has any silica in it your water pump will last about a month . Yamaha's like fancy coolant .

be prepared for the propylene vs ethylene glycol debate .

from what i have herd propylene is better in aluminum because of the metals porosity . not gonna go into it to much , again just what i have read , never put it under a microscope to see how well the two bond with aluminum .

Mixing antifreeze (prestone) stronger will make you're cooling efficiency worse. Ethleyne glycol prevents freezing, it does not improve thermal transfer. I've heard very good results from people that swithced to Engine Ice, it's only worth it if you have overheating issues, otherwise just run a standard 50/50 mix of common antifreeze.

I have never ran anything but engine ice :banana: It will boil over under extreme conditions (mud caked rads in tight technical stuff) but it's rare. Engine Ice is also "environmentally friendly":thumbsup:

Search this forum for "Evans". That is the coolant that I have heard about that is supposed to be the absolute best but in my opinion, you cannot go wrong with Engine Ice... What is it, $20 for a 1/2 gallon... not really expensive when compared to oil and gas:busted:

it's half water.

so, you dont mind paying $10 for a quart of water?

It maybe half water giving it excellent heat exchange and boiling points but the other half is an excellent corrosion inhibitor with similar properties allowing us to keep it in the bike for years... so yes, I would say it's money well spent.

In your part of the world water is hard and not overly corrosive but will develop a lot of scale especially if it evaporates, where I live the soft water out of the tap is not something you want to put into your cooling system either.... sure we can go down and get a cheap bottle of drinking water or DI and mix it with an off the shelf coolant for a lot cheaper but my experience tells me that does you no good when you have to shut the bike off because the going is slow and your boiling over.

If they sold it in a concentrate cheaper... I would buy it, but comparatively speaking with other things I either pour into the bike or bolt onto it and factoring in how long it lasts I would say $20 is a steal:excuseme:

What do you use?

I hope people don't think their bikes are running cooler with the likes of Engine Ice and Evans. These coolants just have higher boiling points than a 50:50 mix of regular coolant/water (which boils at ~260 deg F). So, if your bike with EI or Evans doesn't boil over now, when it did with a 50:50 mix of regular coolant under similar conditions, then you can bet it's running hotter than 260 deg, but under the boiling point of the EI/Evans, whatever that is. The fact that these engines don't melt down is a testament to the wide tolerance margins built into these bikes.

I use it as well. And let's not forget, it's blue which really acccents the whole bike.:banana:

I did a search a long while back on what worked and stumbled on to the mixture. I don't remember if its 50/50 water/prestone or 75/25 water/ prestone I think its the latter because I don't have to worry about freezing but its something along those lines...the only thing I remember for sure was the mix was one whole gallon.

I'm thinking of mixing in more water wetter though. There is a guy over on the YZ forum that mixes a whole bottle of WW to 1 gallon of mixture.

Have you found the mix loses its red tint after a while? The extra coolant in my overflow tank is almost clear now :banana:

Exactly - I just wanna keep the coolant in the bike... there was however an oil additive (2 cool or something like that) that touted cooler operating temps... anyone using this?

Can't really say 'cause I use the Prestone Extended Life 5year/150K stuff that's orange/red to begin with.
