So my 2001 sixxer has been overheating now and again recently. I did a system flush and added some anti leak about three weeks ago and that fixed the problem until last night. The first time I had the problem I thought it was a leak because there was coolant all over the engine, but this time around I did a little investigative work and noticed when it started to "leak" that there was huge amounts of pressure in the coolant hoses, as well as a P1285 code makes me think my thermostat is junk and is sticking... Thoughts or comments? Any insight is greatly appreciated, and as always, thank you MF'ers!

 

Thermostat! Problem solved. I swung for the 180 degree over the 195 degree OE stat just to keep things cool.
