Hey guys for some reason, my speedometer refuses to work. I have taken the front right wheel off and cleaned the sensor really well but it still wont work. 4WD still works and everything else seems to show up on the display very well.

Here is a video showing what I mean.


I also have another problem. Cooling system issues.
About 2 years ago I had antifreeze spewing out of the reserve reservoir of my 2003 Sportsman 500H.O. The heat sensor light would start flashing and eventually it was unridable. I let it sit for 2 years before trying to fix it. I replaced the mechanical seal, checked that the water pump WAS working, it was. I also flushed out the whole system with water so no stop ups. I purchased a new thermostat and new Radiator cap. Also, the radiator is clean as it can be and the fan is hooked direct so it spins as soon as I turn the key on. Iv put fresh anitfreeze in it and this is what happens now. After riding a while, when I get home I see antifreeze all over my belt cover. It's coming out of the reserver reservoir because it's level goes down. The overheating light does not come on though. Anybody know what's going on there?

 

guessing, but if the awd is working and assuming maaybe the tack is as well it might be a bad wheel sensor even though you cleaned it. as far as the coolant, do you fill the overflow tank to the cold mark and then it heats up enough to spit out the cap?

 

i would agree as well with the wheel sensor. you can test the sensor. all you need is a l.e.d., 9v battery and a resistor.

 

The issue with the radiator blowing coolant out the reservoir could be also an engine problem from your previous overheat issue. Cracked head or warped,leaking head-gasket possible. You can check the water pump pressure to see if its operating correctly. Then do the bottle test to check for combustion in the coolant.
