Hey OPT, how you been? I have a quick question about my 2011 sportsman 500HO Touring; I need to pick up some antifreeze that is compatible with the antifreeze that came in it. I only need to add a small amount to the puke tank to bring it up to the full mark and don't want to cause any problems, but the nearest dealership is 50 miles away.

 

Almost all coolant now is for aluminum radiators whether 50/50 or 60/40 and is suitable. Except leave Dexcool alone! OPT
50/50 good down to -37 degrees Fahrenheit to where 60/40 protects down to -62 degrees(arctic conditions!) Either one too damn cold!
