I just filled my 954 up with pure Spring H2O and Water-Wetter after yesterday coming home from work.

The bike has digital readouts, including temperature. Normal operating temperature is 180 degrees {F}.

Yesterday, outside temperature: 91 degrees.
-When I would be stopped in traffic, the bike would go up to 209 degrees {F} or so. If I was doing less than 45-50 mph, she would struggle to drop below 195 degrees {F}.
-Coolant - factory 50/50 mix.

Today, outside temperature: 90 degrees.
-I deliberately had the bike get to 205 degrees before I started moving. At 35-37 mph, the temperature dropped to 195 degrees {F}. At 50 mph, the temperature would drop to 180 degrees {F}.


It seemed to me that the bike would be at a LOWER temperature at a LOWER speed with Water-Wetter than with factory coolant. Do your own thinking and purchase accordingly!

I'd me more than willing to change my coolant to Engine Ice if someone would send me a sufficient amount of the stuff. I'll purge my system again, and put the stuff in, and give a report as I did with the Water-Wetter!
I always run the stuff in the KTM in the summer, and I'll do the same for the 954 now too!!

I don't doubt your results, but there is one flaw in your procedure. You're checking coolant temp, not engine temp. I'm not going to speculate if your results would be the same or different if you checked the engine temp instead, I just wanted to point this out.

I believe that an engine will run cooler on a water/water wetter mix vs a water/coolant mix. Pure water has a better heat transfer coeficient than a coolant/water mix. The coolant serves the purpose of raising the boiling point and lowering the freezing point of the radiator fluid. The coolant also provides some corrosion resistance. Water Wetter is supposed to improve the heat transfer properties of water and also provides corrosion resistance. Remember to used distilled water in your cooling systems.

I've been running Water-Wetter for years. I believe in the stuff. Yes, they say it improves heat transfer properties. I always run a 50/50 mix with coolant and add the required amount of Water-Wetter, which I believe is a couple of ounces for a MX bike's system. I think that's the best of both worlds. I would love to hear Engine Ice results. Maybe you should contact them, direct them to this page, and issue the challenge. Maybe... just maybe... they might send you some. :)

To lower the engine temp you would most certainly see a rise in water/coolant temps as the BTU's are pulled from the engine and transferred to the water. If your pulling more heat out, it has to be stored somewhere before the heat can be transferred to the air via the radiator.

Sirthump is right, to measure the cooling properties of the coolant correctly, you would have to take a reading of the cylider head/block temp, as opposed to the water temps.

Remember what your trying to do. Trying to lower the operating temp requires sucking the heat out of the engine metal and transferring the heat to the radiator via the coolant. So the coolant must get hotter.
So if I read your test correctly, the water wetter worked perfectly! More heat was conducted to the water and then to the radiator and then out of the radiator via the fins.

Somebody tell me where Im wrong!

About 12 months ago, there was a LARGE THREAD on the whole engine ice thing, w/ engine ice (member) included. My thoughts after reading the thread were as follows:

If it ain't broke, don't fix it. My 426 runs just fine the way it is.

just my $.02
