Coolant Questions Answered

Recommended Posts

I was introduced to this forum today. I did a search on “coolants/antifreeze” to see what people were talking about and was floored at the number of topics on this subject. I knew that high temperatures were a problem in four-strokes, but not this bad. So, I thought I would give you all some insight as to what coolants actually are and what their true purpose is.

Now, being from Engine Ice, I am a bit biased and I admit it. However, most all of the products on the market are excellent products, but each has various uses and applications for them. We produce Engine Ice for specific high intensity and high heat applications. It really is not designed as an “everyday” coolant; it is for racing applications.

There are two basic types of coolant/antifreeze, Ethylene Glycol (EG) and Propylene Glycol (PG) and then there are surfactant products such as Water Wetter from Red Line for example. All of the products mentioned are good products, just offering different things.

Ethylene Glycol (EG) – This is basically your “Prestone” type of products. Maxima’s Coolinol, Pro Honda Coolant and Spectro Coolant are examples of this type of product. It is basically the same as the coolant/antifreeze product you can buy at the auto parts store, but “silicate-free.” This is important, don’t get the stuff from the auto parts store unless it’s silicate free. Most are pre-diluted for easy use; they are diluted with a more pure distilled water or deionized water (deionized water is explained below). This is better water than what you can buy at the grocery store. You really shouldn’t call an EG-based product a “coolant,” an “anti-boil” product would be more accurate. EG is made very cheaply and its primary purpose is to eliminate boil-over and to keep your system from freezing up. That’s basically it. It is not designed to actually reduce temperatures. If you are driving a car or a cruiser-type bike that does not have a temperature issue, these are fine products.

Water Wetter - It is an additive product. Water Wetter is what is called a “surfactant.” What this means is that it reduces the surface tension of the water or in other words, it allows the water/fluid to “rub” closer to the metal allowing it to better draw off heat. Water Wetter works and it is good stuff. However, if you add it to an EG antifreeze product your results are minimal. Added to water, you will see a significant difference in temperature reduction. But it will not raise the boil point of the water nor does it offer any antifreeze protection. So your engine may run a bit cooler, but when it gets hot it will “spit out” the coolant before other products do. That is not good, because now you’ll have less coolant in the engine. Using more than the recommended amount (4 capfuls to a quart) is a waste and it will not make any difference, only use their recommended amount.

Propylene Glycol (PG) – This is what Engine Ice Hi-Performance Coolant and Evans Coolant is made of. Evans is 100% PG and has an extremely high boil point of well over 300oF. They recommend you make some mechanical changes to your system in order to use it. So, we will eliminate them from this discussion. Engine Ice is a diluted ratio of PG and Deionized water. The process of de-ionizing water eliminates all of the impurities that can do harm to your cooling system. Regardless if you are using tap, bottled, distilled, spring or R/O (reverse osmosis) waters, it can still contain minute particles of iron, magnesium, rust, lime and calcium. Many of these waters also contain chemicals, such as chlorine, fluorides and acids. Want proof? Take two different brands of distilled waters and perform your own taste test. They each taste different don’t they? If water were water, why would they be different? It’s because of the varying amounts of chemicals and minerals in these waters. These minerals and chemicals are what is the cause of scarring, scaling and mineral build-ups in your cooling system. Many also attribute these minerals and chemicals to water pump seal and gasket failures. Engine Ice was developed and tested in the heat and humidity of Southern Florida. Tests have proven to reduce operating race temperatures by as much as 50oF in some situations. PG is a lubricant and is a surfactant in itself, meaning it has more capability to draw away more heat than EG-based products and even Water Wetter. It is biodegradable and non-toxic. It will not kill your dog, nor will it kill the plant life at your favorite track or trail. It is also legal in AMA, CCS, FUSA and WERA road racing.

Engine Ice has won over 200 National Championship Titles over the last year and a half including the AMA 125cc West Supercross Championship with Ernesto Fonseca on the Yamaha of Troy YZ250F. You can bet that Yamaha Motor Corporation did extensive testing on Engine Ice prior to putting in into their premier bike in its debut year. It is also used an endorsed by the American Suzuki Amateur Motocross Program.

I would put our web site address on here, but I don’t want to look like I am trying to push our stuff too much.

I apologize if this appears to be a spam, it was not meant to be such. Only educational.

And where might one find this product...I've seen Water Wetter but ner Engine Ice in the local auto parts store? That is some great information that needs to be said. Sometimes people forget that horsepower is a product of heat (in a round about way) and the more HP the harder a cooling system has to work. I know that on a car it is often the most overlooked system. :)

Engine Ice is not available in auto parts stores, only bike shops.

If your local dealer doesn't have it, they can get it from the distributor Motorcycle Stuff...they are a nationwide parts and accessories distributor.

It will be available to dealers through Parts Unlimited in a few weeks.

We are presently working with TMV in the Netherlands for european distribution.

Our website has their phone number

I have used Engine Ice with excellent results on my 01XR650R and 02 KTM520EXC. Before I switched I used the Honda premixed non silicate coolant. I like the non posion aspect and excellent cooling properties of Engine Ice. I believe.

Hey KLXer If you would just ask good ole UNKLE MOOSE he can get you some. I just baught some for my bike, gonna put in saturday before racing on sunday. I would have gone riding with you and your dad on his show bike, but you guys are just too fast for me :D WHOA WAIT A MINUTE MICHAEL IS GONNA GET THAT BIKE DIRTY? :)

Hmmm...I'll let you experiment on your bike and if nothing blows up (coolent related, we know how you're prone to that kind of stuff ) I might give it a try. :D:)

EIDave,

What would the recommended flushing procedure be. I will switch over to EngineIce this winter and after testing, may remove my overflow tank on my WR :)

Bill - Lose the tank, and switch to the Kawaski 1.5 cap. I made the change with no problems - much easier to pull the subframe now.

Moose - Yes, I got the bike dirty.....I just clean it up afterward. It a process called maintenance. You should try it!

What I do is remove the drain plugs out of the radiators and let it go till it stops. Then remove the cylinder drain and with the plug out, turn it over quite a bit till no more fluuid comes out. Then fill the radiators up with the new fluid and let some of it drain back out to insure I have gotten most or all of the old stuff out. Works for me.
