Temperature switch location

[William Blankinship]

I have a 2011 Kawasaki mule model 4010 with gasoline engine.  The cooling fan is not working. I took the front cover off and unplugged the fan and it works fine on a 12 volt battery. The fuse is good also. I am having trouble finding the temp switch.  Most sources say it is on the radiator but there is not one on this model.  Is in on the engine?

Welcome to the UTV Board!

If in Temp switch you mean thermostat, your part # is  49054-2056,

Thanks. I may need to replace the thermostat also.

I just found out that this model does have a temp sensor on the engine that sends information to the ECU which turns on fan thru a relay. 

I hope to do some more checking today if rain holds off.

 

Thanks

Fan, fuse and relay is good. I can inject 12 volts at relay and fan works.  The sensor on engine resistance seems ok but voltage is not right. I hooked a 100 ohms resistor in hope that would trick ECU into turning on the fan relay with no luck.

I  need to pull ECU and check  wiring and contacts for corrosion. I have unhooked battery in hopes of resetting computer. Raining now.

If ECU is bad I may just install a toggle switch and run fan that way.  

Now that cooler weather is here the fan will not be coming on much anyway.  I hope there is not another problem lurking around.
