OK now I got to admit I am confused here. I was lead to beleive that certain coolants are different which in part I do beleive. Now I should have stated the coolant in question and it is called cool-anol and i also use cool-aide. I put this in all bikes and sleds and was told by either a rep or salesman (not sure) of the company that regular anti freeze for auto's will eat out your seals due to the bigger molecules, Now I think he is refering to a A/F with silicate inhibitors/compounds which I do know for a fact will eat seals. So why not buy a A/F designed for your sled which has no Silicate in it with great anti foaming agents and can tolerate a higher boiling point with the same freezing point and also lower your operating temperature by 20 degrees. We all know heat robs horsepower so this kind of boils down to a personal prefference, like I say what ever floats your boat I guess. So I think this is great that Versatile has access to a lab, so if you could do a test on this coolanol or something similar and compare it to automotive A/F I would be glad to flip the bill for it just send me the invoice for the A/F because now I am curious also and really want to know.
Now I have had 4 motocross bikes in last year and 3 in this year for water pump seals. Now due to the high demand of engine rebuilds these kids admitted to using auto A/F. This leads me to beleive it was the A/F causing this seal failure, mabee some one else can add to this? The ones we use cool anol in have had no problems.
Now on sleds I will admit to never replacing a seal on the pump but the only sleds i service are relatively new and have factory A/F in them and I replace it with the above stated.
So really Versatile if you could do a test on this cool anol I would greatly appreciate it because I do beleive in this product and I am happy to pay for it.
The other part I don't understand is why such the cotroversy about this A/F it is only a couple of bucks more and is designed for your sled with great benefits, so why not.
Just a few more sled A/F you might want to research
Cycle logic engine ice (garbage)
Honda HP coolant
Water wetter is a great additive to keep your engine 20 degrees cooler, just read the bottle.
For those wondering what silicates are, they are corrosion inhibitors which in turn act as an abrassive to mechanical water pump seals. I do know that the Honda HP coolant got right away from the silicates and used an organic corrosion inhibitor. Just remember your sled RPM's and small mill should be taken into consideratuion here, way different than a cars cooling system.
Let me know the results, going away on holidays late tonight for 3 weeks of sledding, happy new year to all. Brad
