500 HO overheating

Sorry, if this has been covered, I am new to the forums and tried searching the existing posts with no luck.

I have a 05 500 sportsman HO. The fan turns on and off properly, I think the coolant is flowing properly due to movement of the fluid in the reservoir. The motor does not seem any hotter than normal, but the display flashes HOT engine. Can anyone point me in the right direction?

Thanks

Take a good look at the front of your radiator. Make sure its clear of dried mud. If the "fins" that make up the radiator are clogged they will not be able to dissipate heat properly. Ive had this happen to me shortly after purchasing my quad after the first good mudding trip.

I cleaned the radiator fins out this morning, because it was a little dirty. It didn't help. I topped the coolant off to. This seemed to make it where I could ride the bike a little longer before the display warning came on. I think it may be a faulty sensor but I am not sure. I don't want to ride it in case I am wrong.

Take a good look at the rear of the fan and inside the shroud also.
The one I'm working on now looks spotless from the outside, but upon crawling around underneath I noticed this.

Sounds like you have a faulty sensor....if the quads not overheating then you can rule out the thermostat unless its just opening enought to let some coolant pass...500's run about 180 to 190 degrees before the fan comes on and will cool down to normal 150 to 160 degrees..is the oveflow bubbling? Are you loosing any coolant? That radiator looks beat...if fins are clogged or bent up you won't get the proper air threw the rad to cool the quad..and that maybe throwing your light on....bad circulation..Muddie49

Most common reaSON FOR OVER HEating is a dirty radiator. It takes a very detailed cleaning to get the proper amount of air flow to prevent over heating.
