Cooling System issue on an 06
Hey guys, so here's the story: I noticed a few drops of coolant leaking from a few hoses and around the water pump so I decided to change all the cooling system hoses, the water pump seals, and the thermostat and t-stat seal. At the same time I did a thorough cooling system flush with distilled water only and decided to run engine ice to keep the temps a little lower because I do a fair amount of commuting during the summer on my bike.
After flushing, filling, and then bleeding the air out of the cooling system I ran it into town to grab a few things and when I came back to the bike I noticed there was a small puddle under the reservoir overflow. My initial thought was that I put too much in the reservoir. That was last weekend and this evening when I opened it up to take a look, I noticed the reservoir was still full and when I opened the fill cap, air came rushing up through the reservoir and I couldn't see any coolant down in the radiator.
Not sure how or why the reservoir was still full and the coolant didn't go back into the radiator but I figured I'd fill it and bleed it again. Maybe I didn't bleed it well enough last time? I put coolant in and ran it to bleed. I noticed the return line coming from the t-stat didn't get hot until 190F. The level dropped some so I put a little more engine ice in. Then, just under 200F it starts boiling out of the radiator fill and then the level drops and then boils out again. I shut the bike off and the level in the radiator stayed the same.
I'm not exactly sure what's going on here. Maybe a mixture of things? I'm really hoping not head gasket!
