    I called the dealer & they tell me that there is no relays?But they also told me that the temp switch is on the rad .it actually is on the engine.I found a component that is sealed but looks like a circuit board.does anyone know how the fan works? Temp switch tells something to turn the fan on.Does it send a signal to the ecm which in return tells the fan to come on?One would think that there would be a relay?

I read somewhere someone had the same problem as you with the fan not kicking on. the guy took his to several dealers and finally got it fixed. he said it was the fan relay. so check the relay for the fan. if it has any mud or dirt in there then you'll get high resistance or even no connection causing your fan to not work and your engine to overheat. I hope that works for you, good luck! :D

When my cooling fan kicks on it runs intermittently.


The fan will only run when it needs to. It's on a sensor. The only time mine comes on is if I'm hauling something

What is error code 51 and 58 how do I check gr4ound fault on my sportsman 500 or is it something more common like changing fuel filter


51 is a injector on #1 cylinder is stuck open.. will need to check wireing for damage first. 52 is cooling system fan issue.. fan is overload condition or maybe shorted to ground. Will likely have to chase wires to find issue.

I have a 2004 polaris sportsman 500 when it gets hot it cuts off and back fires


Does the cooling fan ever run when the engine is hot? If not, you may have a problem with the fan thermostat.

For the record, spray carburetor cleaner does no good if it's sprayed on the outside of the carburetor with the engine running. That's not what it's for.

Fan wont turn on


Sounds like a thermostat issue....inspect the rad and you should see a thermostat with wires ...check for corrosion on the terminals.

You will have to get the cooling fan working before you look any further. It may be best to have a coolant system pressure test and a compression test done to eliminate engine fault also
