Axys running hot - bad impeller?

[MrIQR]

Last two rides my Axys has been running 150-160. It has always ran 127.

Could my impeller be going bad?

Snow is deep, face shots plentiful, air temp in the teens..

Coolant is circulating and melting snow on the tunnel.

Really scratching my head on this one.

I remember having a impeller nut come loose on a Iqr 600r motor, is that still a thing?

Air in the cooling system by chance?

 

[MrIQR]

Update/edit Tunnel gets warm enough to melt snow but is barely Luke warm, I’d guess 80 to 90 degrees and this is when the gauge reads 165 and the motor is HOT.

 

[MrIQR]

I don’t think so but I’m going to try to burp it.

When I’ve had air in the system the tunnel would stay cool, mine gets warm

i would check the thermostat. sounds like its not opening properly. with a bad impellor it should just keep getting hotter.

I’m guessing this is my problem. Going to pull the Tstat and try it without.

I think that is the case and only the bypass is allowing the coolant to flow and why it’s running hot but not completely over heating.

I pulled mine on my 2017 and gutted the T stat and plugged the bypass and the sled ran to cold .

What year axys? My 19 had a broke thermostat and would overheat. Sad that Polaris only builds parts to last through the warranty.

 

[MrIQR]

It’s a 2017.

Appears the tstat failed and lost the tip like power mods video.

 

[MrIQR]

Was able to fish the spring out..

 

[MrIQR]

Finally rode it with the new thermostat, ran it’s normal 127... case closed
