ok ill have to check the thermostat and see if that is the problem. and ill look at the radiator but i dont think that is the problem. but couldnt hurt looking into it. any other suggestions while i work on these? thanks all

 

I take it the fan runs OK, and you are sure all the fins are clear? It might be possible that the temp sensor is faulty, too.

Also, if you change the coolant (and if you haven't, you should) be sure to use motorcycle specific stuff, like Honda's or a variety of aftermarket stuff.

Automotive coolant has silicates in it, abrasives that help control corrosion. The mechanical seal in motorcycles (and quads) is much smaller, and doesn't live long with the abrasives, so motorcycle stuff doesn't use silicates.

 

yeah i have checked all the fans and the radiator is clean and clear. so im going to change the coolent on it and see if that makes any differance. if not then i will check the temp sensor. thanks

 

May as well pull the thermostat and either just replace it or check it, while you've got the coolant drained.

 

do u know where is the best place to get a thermostat from for cheap?

 

I would suspect it is a Honda specific part... Even so, I can't imagine they would be much.

 

ok so i just got done changeing the oil in it today. and i rode it for about an hour and the over heat light didnt come on at all. but the cooelnt boiled over so far that it came out of the over flow tube. so the coolent is boiling when it gets hot. any suggestions on what that could be?

 

Was the fan running?

Have you checked the coolant level in the radiator?

If the seal is bad on the radiator cap it can loose coolant, and/or not pressurize the system properly. Could still be the thermostat.

At 6 years old, it should have the coolant changed.

 

yes the fan was running

how do i check the coolant in the radiator?

why was the coolant boiling? it shouldnt be doing this right?

 

No, the coolant should not be boiling. The radiator cap is located under the little hatch in the middle of the front rack.
