I am in Rexford, ID now and we stopped to have the clutch adjusted on the snowmocycle. The service guy here swears by the engine ice stuff, but also says the Honda coolant is good too. They carry both. They were booked solod so they dis not have time to drain and flush my system to put one of them in. I got a bottle of this other additive he recommended to top it off with till I can have my system drained and flushed when I get home. Brain burp, can not remember the name of the stuff and it is out in the chase vehicle with a few ounces left.
