Beefed up the the antifreeze for the winter. It was only good to about 15 below. Here in good old Vermont you got to have it down to -35 or so. And a question. So I drained out the old stuff. Now when I tested the new coolant cold, it was good to -35 or better freeze protection. After I put it in the bike and ran it for a bit,(warmed it up), it tested at only -25? :dunno Does warm coolant/antifreeze test different than cold? :dunno2:
