    bird is overheating... I think, help?

    So my recently purchased bird is having problems in traffic. for the third or fourth time and a redlight the temperature gauge has risen to just below touching the top white hash mark. it then begins to puke coolant into the reservoir over flow and out the overflow draft tube. On occasions when I've parked it when it was hot, but not quite to this point the moment i shut off the bike it sounds like a boiling tea kettle, and bubbles and spurts into the plastic overflow tank. I have drained the system once, I filled it with tap water ( yes I know it should be distilled) and water wetter. this did nothing to fix the problem. The fan is coming on , so all I can think of is the radiator cap worn out? Could it be preventing the bike from holding sufficient pressure to keep the water liquid at high temperatures. The bike hasn't once boiled over ( IE popped the cap and flowed out of the top of the radiator)

    Thermostat would be the first thing I checked if it were mine.
    Where are we going...and what am I doing in this hand basket??

    hmm, if the thermostat weren't opening wouldn't it come close to overheating all of the time? It only gets hot when the bike isn't moving, If the radiator wasn't flowing wouldn't it heat up regardless of the air passing over it?

    Re: bird is overheating... I think, help?

    bubbles caused by a bad cap, or just bubbles in the system? when i filled the tank i let the bike idle for about 2 minutes with the cap off.

    Not if it's stuck partway open. Does it seem to take a while to warm up?

    So pulled the radiator cap, the coolant level was still good in the radiator itself. I left the cap open and ran the bike for about 4 minutes, the bike took about that long to heat up from cold to half way up the gauge as before. Anyway, I ran the bike up to temperature and shut it off. once again I could hear air moving around. I checked the large radiator hose and I could feel air bubble running through it. once again it forced water into the overflow and all over the ground. I could hear the bubbling boiling sound once again.

    Re: bird is overheating... I think, help?

    Sounds to me like proper care hasnt been used when the radiator has been refilled at some point... There are a few threads around here that discribe a similar problem to yours and they have been the result of trapping air in the coolant system after a drain and refill....

    The engine will never boil over and pop the radiator cap in the way that you describe.. inside the cap there is a sping loaded seal when pressure becomes to great then the seal is pushed up against the spring and water is allowed to flow out from the radiator into the overflow bottle.

    I know it just wouldnt be right to kill all the stupid people that we meet..

    But do you think it would be appropriate to just remove all of the warning labels and let nature take its course.

    Re: bird is overheating... I think, help?

    oh yea, I didn't think of that. What really scares me is that fluid boils out when the bike is shut off. The last time I saw this happen in a car it was a bad head gasket causing excess pressure in the cooling system. And I did see a small amount of something black in the cooling system which I'm praying isn't soot.

    Re: bird is overheating... I think, help?

    Alot of people dont realise that when you shut down an engine that there is a dramatic increase in water temps.. Even if the vehicle is stationary the water pump will force water to circulate and since fans are employed on radiators water continues to cool while the engine is running. When you shut down the engine you also shutdown all mechanical means of water circulation and other means of flowing cool air through the radiator.

    So now enters the area of hydrothermal circulation (i think its called..) water in the engine heats and opens the thermstat, this causes hot water to escape the engine and cooler water from the radiator to renenter the engine ,as long as the readiator is able to shed some heat there will always be a cool/ hot varience between engine and radiator and the circulation process will continue, since there is no airflow or fans cooling the radiator not a much heat will dissipate and the engine will continue to superheat the water for quite sometime after shutdown. It not uncommon for water temp to rise by upward of 25C

    Mmm, sounds like head gasket to me, try back flushing the system b4 doing anything else. Then completely drain system, and refill with a dedicated coolant.
