Bashan It attaches to the thermostat housing. On a side note, both radiator hoses are hot so it doesn't appear that there is circulation through the radiator. I'm thinking I have a water pump issue.

 Untitled by mxmattaz, on Flickr  Untitled by mxmattaz, on Flickr Rich, I am aware of the difference between the reservoir fill spout and the radiator cap spout. I continue to get a full reservoir for some reason as well. I noticed that the return line from the carb is the one that is attached to the radiator fill spout. The coolant in that line is very hot and continuously produces bubbles. |

I forgot to mention that last night after a thorough burping and obtaining what appeared to be normal operation at idle for several minutes, I took it for a ride. I mostly stayed at 45 MPH for several miles with no overheating. It was a very cool AZ night so that was to my advantage. However, when I took it on the highway and ran it at 65 MPH for about a mile, the gauge quickly entered the red zone.  |

I think the splines on the impeller are bad. If so, can the impeller be replaced without the whole water pump assembly, or is it an all or nothing deal? |

Can you see the coolant moving in the radiator? Kind of. Something I am noticing is that no matter how many times I "burp" the system and test it for a ride, there is a continuous stream of bubbles emitting into the cup the radiator cap screws onto. It is coming from the hose that is attached to the carburetor. I am thinking that I am picking up air somehow. Also, no matter how long I let the bike cool down after a good burping, when I open the cap, there is a little pressure and coolant escapes. It's not much, but it didn't do this before. I am not sure I understand the "swirling" you are referring to Rich. Is that from the coolant returning to the cup under the cap? This is really starting to frustrate me. I have done nothing but baby this bad boy since the day it landed in my driveway. What would plug my radiator or cause the water pump to fail at 3300 miles? Oh, I double checked the weep hole on the water pump 10 times and there is not coolant coming from the hole. |

Did you check both of those thermostats in a pan of water? How can you 100% take them off of the table until you test them. Did you order a new one without testing the old one? Hmmm? Did you Mattie? OK...lean forward:
Next time listen up.....  No. No I didn't.  ? Yes. Yes I ordered the new one and replaced it without testing either. ? I still have the original and will run the test this morning and let u know. ? *palms stinging cheek* Both thermostats tested. Both operating properly. Still overheating. Fan works when heated before overheating. Water pump??? |

Did you do the swirling test? That is for the water pump. Sort of. I think. I'll do it again Zen Master. *heads to Walmart for another bottle of coolant* |

So the fan is not cooling, or the coolant is not circulating, or both. Sounds like a water pump to me. If it's the bike in your Avatar then here is your pump; Water PumpThe fan comes on when there is enough coolant in the system. After it overheats and loses coolant then the fan stops turning on cause it needs burped. Thanks for the link. Is this a job for a mechanic or simple enough for me to do? |

If it's the bike in your Avatar then here is your pump; Water PumpI am of the opinion that the fan and temperature sensor for the fan are operating properly. I am keen to your idea that it is the water pump it does appear that the pump functions at times and cools down the system a little bit every once in a whileas I do get a fluctuating temperature gauge. and at other times I do get a hog reading that is lower than an overheating reading that is abnormal. if that sounds like a bad water pump to somebody would you please confirm it?I am just a little shocked that a scooter I purchased in June has a bad water pump with only 3300 miles on it.I have taken unbelievably good care to do all maintenance as suggested. |

The only leaks I can find are coming from the reservoir cap.
Cooling fan is coming on until air gets into the system when pressure blows coolant out res cap. I'll do the swirling test mañana.

Crap! Installed new thermostat and I'm still overheating. Back to square one. What next boys?

Thanks! Thermostat is screwed into the radiator right? Do these go bad that quick?
