engine temp at idle - what is normal temp

[johnye75]

If I run my sled in the garage (50 degrees outside ) just idling ,should the engine temp stabilize at some degree, or will it keep climbing. Mine keeps climbing and I shut it off when it crosses 150sh. I wonder if that is normal ? I need to update my maps and the update takes longer, so I need to run my sled to have the screen running (no battery in my sled), but the update takes too long and I need to shut off my sled before it completes the update and overheats. thx!

It will keep climbing. No snow hitting your heat exchanger to cool down your engine coolant.

You could wait until summer and hit the heat exchanger with a garden hose to keep temps down. Might work?

Thank you for confirming it is normal, that was my main question. I was running a fan blowing under the tunnel, I even added an ice bag to make the air cooler, but I still could not keep the temp low enough. I may try that hose idea - thx!

Normal- All mine keep climbing-my 2018's shut off automatically at about 10 minutes if the throttle isn't touched, I don't know if it's a Polaris or EPA thing, 3- 2018 Axys Pro-S.

I also believe that the Polaris water pump and its configuration in the engine will not circulate enough coolant at idle, yesterday on our ride in the Snowys (ambient temp 45 to 54*F) I would have coolant temps rising at idle and still running at about 20 to 30 mph at 3500 to 4200 rpm, I had put heavy wet snow on the tunnel behind the seat and that helped , so we started running so the engine was staying at 5500 to 6500 and the coolant temps never went above 128 for the rest of the day (6 more hours) . Just observations from yesterday and had scratchers down and new 3" heavy snow on 5 to 8 feet of base every where we went, probably the last ride of this season as after May 30 the USFS shuts us down off trail in the Forest!
