Not meaning to hijack this...ok...I am. Haha. But I'm running an Afco radiator in my ERC Lightning sprint. 2008 R1 on methanol. Not sure what's happening but there are no leaks. Ran hot laps last night, no issues...then came in from heat race and it was up to 245 and steam coming from overflow tube. Let it cool and checked coolant, and I lost maybe a half quart or so? It was full and bled of air before the night began. What's happening? Anyone got any ideas?!

Never had issues with it getting hot until last couple races last year. Like I said, no visible leaks anywhere.
