Evans Waterless Coolant?

[Samjp22]

Anyone running this stuff? Reviews on it and everything look good or is there another particular brand out there that's highly recommended? 265 degree test on a polaris triple https://www.youtube.com/watch?v=VkNz-ANfUkc

Best stuff you can by, GNCC tested Four Stroke Tech approved! First time I tried it Gas Gas had given me a 450 quad they made for a few years. The top end was a Suzuki Z400 copy, but it had smaller water ports and when I built it to a 465cc big bore we could no keep it from over heating. The only change was to the EVANS, never had another problem. On our V-Twin Kawasaki's in the GNCC races we would get the rads plugged with mud on the first lap and they would over heat. No much we could do to keep from getting plugged but with the EVANS the bikes could over heat and we could still finish the race with out boiling over and blowing all the coolant out. This stuff just flat cools better then anything out there because of it being waterless.

awesome thanks for the reply, seems like its worth the money!

[SHIFLITE]

Run it in my Big Bore 330 and have never had a problem with the motor overheating....

[Samjp22]

Im thinking of using it in my 250r just so I don't boil over again. They have that fluid your supposed to flush the system with before using the waterless coolant. All the videos I have seen people just suck/blow all the old stuff out. What do you guys recommend, buying the flush as well or suck/blow?

[TrikeGasm]

I think I read that with Evan's you can still have 3% water in there without any problems. Of course the goal is to get all of the water out but if you blow all the stuff out well enough I think you should be just fine. Also I think a lot of people just flush the system with the Evan's and then let it sit in the sun and evaporate the water out and then put it back in.

[Samjp22]

yeah was reading that as well, I'd have to put it in a hot plate and heat it off, too cold here for that lol or just flush it out then put new stuff in. Only liquid toy we've got

[onformula1]

It is good stuff.

Blow out the cooling system with compressed air.

This is what I use-

It works great and seems to be about $10.00 bucks cheaper.

If you don't have a overheating problem I run distilled water with a bottle of Water Wetter from Redline

http://www.redlineoil.com/Products.aspx?pcid=10&

Its like 8.00 bucks a bottle. It makes 3-5 gallons per bottle, distilled water is like 79 cents a gallon. That like $10.37 bucks for 3 gallons!

Cool, I have a friend that has a house in Hermosillo, Mexico.

I always ask him if he see's any cheap 3 wheelers down there.

I'm guessing he says no. I've seen only 2 here in 15 years. I'm sure they exist, but I doubt many still run.

I use evans coolant, its good stuff. Some bad things about it, it boils at 370+ degrees, if you overheat, you will never know it. I found out about it on ktmtalk.com, alot of them used it in their big bore 4 strokes and big 2 strokes. It doesn't cool as efficiently as water/anti-freeze and runs slightly hotter. To a point it actually runs a good degree hotter than water and anti-freeze/water-wetter. Alot of people used it at first to cover up overheating issues and they just ended up costing themselves more money.
The good stuff about it is even when it is 300 degrees, it is still transferring heat and not creating air pockets. When coolant boils, it doesn't transfer any heat. It also expands far less and is more stable, you can use a lower pressure cap and keep similar cooling. Basically, don't use it if you have a chronic overheating issue and want to "pretend" it doesn't exist, also keep away from it if you have extreme cold temperatures. Those are the big 2 downfalls. I use it as the riding I do on my dirtbikes, involves high speed, moderate speed and a good part of slow under 10mph weaving though trees, stuff that your bars don't fit between trees(we call them Hero Sections) and stop/go trail marking for event, those are the times that most of the bikes boil and it works to stop that. It won't stop a bike from overheating, won't cool it a great deal better and can lead to bigger problems in the end if you have a overheating problem. It will stop the bike from boiling over in a tight, nasty trail section, mud covered radiators, knarly hill climb and slow/stop/go riding. If those condition are for a extended period of time, you are doing more hard to your motor/cooling system, as you don't know it is running hot. I put sensors on my radiators to alert me to when they are running very hot.

[deathman53]

this pretty much sums it up

"I used evans in my cr500 and it worked great. It never boiled but it did expand 7% of volume so I still use the coolant recovery bottle.

Evans is perfect for the REALLY gnarly stuff where you normally blow off conventional coolants even with a recovery bottle. Here in the dez you dont want to use your camelbak water too many times to refill the rads. Enter Evans.

Jebs comments about it normally running hotter MIGHT be true, BUT a bike will for sure run even hotter without much water in the rads so out of the two choices evans is the clear winner.

The other comments about masking issues might be true too BUT where we sometimes ride there are only a handful of bikes that dont overheat. Usually 250 two strokes are fine, the yammies anyway, 300s do and about ALL of the four strokes (without fans). So nothing is masked, it just the motor or the rider.

I dont use evans now since my 200 seems impossible to boil and my new 450 has a fan and seems to work pretty well too. But I could see evans still being a good choice for purchase for other reasons. One is a leak in the rads isnt as big a deal as conventional stuff since there is almost zero pressure. Again, when doing NASTY remote rides or adventure riding it could save a ride or life even.

As said earlier you do need to be smart with the stuff. If your stuck on the trail and not moving and more trail nasties ahead, for sure stop and let it cool down or you will wish you did "

and
"As long as you understand it's raising the boiling point.
The engine is still getting hot.
Like Flash says, if it's HOT, shut it down."

and
"You do have to have a little common sense. When the thing starts heating up like a nuclear furnace, shut it off and let it rest a bit. It's not like it is a surprise - you get all of that metal creaking and heat between the legs to let you know you are approaching uncharted temps."

and
"You've gotten plenty of "don't use Evans!" advice, but there's another side to the story. If you understand the tradeoffs, Evans can benefit you like it does your friend. The tradeoff is that that in exchange for no-boil over, your engine operating temperature may at times be higher that it would be with a water based coolant. Bear in mind that "higher" is not the same as "too high". The question is not whether an engine with Evans runs hotter than an engine with traditional water/glycol coolant. Rather is whether that higher operating temp poses any kind of unacceptable mechanical risk. My experience with the 300 2T is no, it does not. Besides, an engine with the water based coolant is only running cooler than the Evans engine up until the point where the water-based stuff begins to boil. Boilling creates an insulating vapor barrier against the water jacket that causes the cylinder temp to skyrocket. Maybe Evans is overkill for the trail rider that can stop and let things cool down, but if you compete that's not an option. Evan's prevents DNF's from boilover. Keep in mind that Evans is not a cure-all for every overheating problem, but it's not snake oil either. For your model year bike, you are probably better off trying to solve the problem with jetting and a fan kit; but if that does not do it - or if you race, Evans may be worth a look.

Water transfers/exchanges heat better than least most other mediums.

Increasing the percentage of antifreeze, increases its boiling point but it will also transfer heat less effectively therefore causing the vehicle to run hotter so it’s a bit of a catch 22.

Atmospheric pressure is what determines the boiling point of any liquid . . water boils at a lower temp at 10,000 feet than it does at sea level.

If you increase the pressure rating of the rad cap, the boiling point of the rad fluid will increase regardless of what it is . . if you increase the pressure rating of the cap beyond the amount of pressure the rest of the system is capable of handling, it will develop leaks.

Water wetter will improve the contact of the coolant with the cylinder and the same or similar compound is used in some anti freezes but adding a bottle to a system will not lower temps by much . . it’s more of a case where “every little bit helps” if you’re running near “boiling”.


If you have a marginal cooling system and your bike runs hot, in addition to jetting as another mentioned, you can try a 1 step cooler spark plug, run slightly more clearance on the piston and/or apply some type of thermal coating and possibly a friction reducer to the piston etc . . mahle has been using friction reducers on their pistons for at least 30 years . . the company below is one that does this and it will not come off.

I’m not a chemist but here’s some info I know about anti freeze and cooling systems.

Not all water is the same . . tap water has minerals so it is best to use something like distilled or reverse osmosis water in the rad.

In effect, evans is actually nothing more than straight antifreeze . . NPG stands for non aqueous propylene glycol . . all proplylene glycol is the same, so the "non aqueous" simply means that they do not add water to it . . the old standard antifreeze that is made from ethylene glycol and not pre-mixed with water, could be called NEG for “non aqueous ethylene glycol” if they wanted to. . . the + in NPG + simply means that they add ethylene glycol to it . . as you can see by the thermal conductivity, the ethylene glycol is around 85% more efficient than propylene glycol at transferring heat, so this is possibly why evans uses it, because my guess is that if one used straight propylene glycol and rode their vehicle in maybe 80 degree heat or more, their engine would quickly melt.

Another interesting note is that the ethylene glycol is poisonous/toxic, but the propylene glycol is not, and in fact you can drink propylene glycol straight [although it is not recommended] . . it also comes in many food products, shampoos and lipsticks etc, but the most important thing is that adding around just 5% of propylene glycol to ethylene glycol neutralizes the toxic effects of the ethylene glycol rendering it “safe’ or “non toxic” . . evans figured this out and has applied for a patent for this finding which he intends to market.

Since, the ethylene glycol is around 75% more thermally efficient than the propylyene and they both boil at nearly the same temp, pg - 370 vs eg- 388 degrees, one could simply run straight ethylene glycol and it would run cooler than the propylene glycol and would cost around 50% less than the evans.

Since both glycols are corrosive, the coolant mfg’s put anti corrosion agents in them . . some of the coolant additives like hyper kuhl and purple ice have these same agents in them and these additives could actually be added to straight glycols to make your own anti freeze.

You "can" run straight ethylene glycol or ethylene glycol based anti freeze, but because it has a lower thermal efficiency than eater, a bigger radiator and fan are recommended. straight ethylene glycol antifreeze has the lowest cooling point when used at 67% with water.

You "can" run straight propylene glycol or propylene glycol based anti freeze, but because it has a lower thermal efficiency than water and ethylene based anti freeze, an even bigger radiator and fan are recommended than the straight ethylene glycol antifreeze requires.


Evans NPG not recommended for street/daily use.

Ethylene glycol = 0 or very little
Propylene glycol
Water = .5
Other = unknown


Evans High Performance waterless coolant same as Evans NPG + C for daily use.

Ethylene Glycol = 66–70 %wt
Propylene Glycol = not specified but it’s at least 5%.
Water = .5% max
Proprietary Corrosion Inhibitor Package 2 % by weight or less.


Evans Powersports waterless coolant.

Water .5%
Other = unknown but likely similar to High Performance NPG + C.


For every 1lb increase in the radiator cap pressure, the boiling point of the coolant increases by around 3 lbs.

If you want to increase your radiator cap pressure, thereby increasing the boiling point if the coolant, you can simply buy a rubber washer from the faucet/plumbing department of any hardware store that has the correct od . . this should increase the pressure by a few lbs . . use two if they are thin . . if your rad boils over, check the gasket to insure it is still properly seated.

Another option is to buy a higher rated radiator pressure cap . . many stock ones are 1.1 [15.7 lbs], some aftermarket ones are 1.6 [22.8 lbs] . . rocky mountain and some other atv and motircycle parts suppliers carry them.

A gasket with a thick wall like this will work to increase the preload on the radiator cap . . one with a thinner wall has more potential to distort when installing the cap.

You can buy inline temp gauges . . the digital ones have a remote screen that can be mounted on the top of the triple tree or handlebars etc for easy viewing.

Because the boiling point for both ethylene and propylene glycol is nearly the same, a 50/50 or 70/30 mix of either antifreeze and water for example will boil at nearly the same point, however, because of the greater thermal efficiency [cooling ability] of the ethylene glycol over the propylene glycol type antifreeze, any ethylene glycol and water mix will run cooler [or make your engine run cooler] than an equal mix of propylene glycol for the same amount of energy [heat] applied.

In a bad summation, because of the poor thermal efficiency of the evans and the fact that if your engine gets to the nearly 400 degree boiling point of the evans or any other 100% antifreeze, it will probably cook something anyway, imo, it’s better to simply run some type of ethylene glycol based antifreeze at a percentage of 50 to a maximum of 75 to that of water.

In other words, in one way, you need the high boiling point of the evans if you use it because it cools more poorly than straight ethylene glycol antifreeze or a mix of ethylene glycol and water.

If you are running propylene glycol based antifreeze, switch to ethylene glycol base and mix it to the ratio you prefer . . prestone and some others still make it.
