I have a 2007 C15 Acert. Bought it at auction in May of 2016. Ever since day one it has been pushing coolant out of the overflow line and temp would rise at the same time. Have put on 30,000+ miles hauling hot mix at 84,0000lbs. Rencently it has gotten more frequent. Coolant temp will rise to 225. Then within a minute or to with out letting off the petal it will drop to 180 within a matter off minute or two. Normal temp is around 190z Have removed radiator and cleaned, replaced coolant diverter valve. Has passed the bottle test for a head gasket. And would think that if it was a head gasket it would have failed by now after 10 months of driving. Anyone else come across this issue before?

Yes, i have this situation in my C15 a lot of water is go out from the overflow line i changed radiator before two month now i clean oil cooler and i rebuild water pump, the thermostat stay the same, the water still go out from the overflow line and the temperature on load of 226Amp is 92'C. What reason make the water going out from the overflow line is drop in cylinder head or something else? Known that i dont have white smoke in exhaust.
