Coolant or Not??

12 posts in this topic

I only have water down my radiators. Will it cause it to rust or should i play safe and mix with coolant?

p.s.i forgot to say we have summer all year round over here, always in the 90's or 100's

cheers.

Only use distilled water. In addition to that you should probably have something that serves as a lubricant for your water pump and seals. I wouldn't run 100% water for that reason.

definitely run a mixture in teh range of 30/70 to 50/50 coolant/water. There are anti-corrosion additives in coolants that protect the metals in your engine/cooling system, besides lowering the freeze point. And definitely use distilled water. Most tap water is full of clacium and other crap that plugs teh passages of you cooling system. Distilled water is cheap and on teh shelf of teh grocery store.

Best coolant to use Dex-cool type. Only Shell, Texaco and Prestomne have Dex-cool approval. My brand is Shell Dex-cool.

Yes you can use water (distilled water) and you should add an additive to it to help lubricate and prevent corrosion, I don't remember the brand and name off the additive, but at some road racing track the only coolant allow is water, because if it spill on the track it will dry fast and nobody will slip on it...

Maybe you could ask road racing guy for more info... :)

Coolant not only lowers the freezing point, but it also raises the boiling point. I would not use water only if your bike is boiling over.

Redline Water Wetter?

But water transfers heat better than antifreeze, meaning that more __-glycol means higher overall coolant temps.

You probably have two intersecting curves. The rate at which the coolant temp goes up with added coolant, and the rate at which the boiling point goes up with added coolant. Go up or down from the intersection point, and you will have a little less effective cooling, or a bike more likely to boil over. Don't really know what that ideal point is, but in Southern Michigan we don't dare run less than 70/30 water/antifreeze, unless you want to drain your bike all the time. Personally, I use Engine Ice , and have no problems. I believe Water Wetter doesn't protect against freezing.

If I had a bike that was boiling over with straight water, I'd maybe add a little coolant, and see if the problem goes away or gets worse. It's just always been drilled in my head that coolant is as important for boil over protection as freeze prevention.

I get my distilled water for free from my garage dehumidifier.

The dehumidifier is really effective - keeps the bike and tools dry.

My wife also uses it in her laundry steam iron.
