2021 hardcore 154. Running no flap but do intend to get a new one back on there. Running 140-150 ° on the trail on the way in. About 125-130° in the off trail. Are these temps normal ? Yes scratch’s are down. Thanks I’m advance !

Awesome thank you. I used the search option but I guess didn’t word it correctly. Thanks again
Yeah I’m much higher temps than that. The coolant reservoir is down below. I’m going to try to add coolant and get the flap back on and see how it does
anybody know of a better scratcher than stock ?

On my 19 156 Alpha- It get pretty warm running down a groomed trail 35-40 MPH- It's reached temps to 170! - scratchers down and had a Polaris flap on there and buddies saying all my spray was going out the back- Put the stock flap back on and temp went down but still light come on at me around 156*F... Coolant bottle is at the cold level and didn't know if topping it off has cured others issues before I do so..
In the fluff I run 113-120*

Sounds very simIlar temps. I hope to get back out next weekend to see if the changes make a difference
The thermostat is 85F. I found mine to be broken after I pulled my engine apart due to crank bearing failure. Rode today after a full rebuild (and new t stat), temps ranged from 100-120 depending on trail conditions, with no snow flap. Maybe those of you running high temps have t stat issues.
I have only 120 miles on this machine. I wound hope the t stat isn’t bad, but yes I know anything can happen.
I would start with filling the coolant reservoir full, ignore the cold fill line.
Will do. Run just a regular green 50/50 mix of coolant ?
check your thermostat, Mine was broken and caused it to run hotter then it broke more and my sled ran 170 down the trail and i was fighting it to keep it cool.
If the T stat was broken would it not be in the open position all the time? and that would cause it to run way cooler than normal?
Not necessarily. They break on one side and get lodged in the housing crooked.
Let you know what I find.... got to get a replacement gasket first before I go looking at the T stat.. My Cat dealer just got the dealership pulled from him...
I can’t see my 21 thermostat being bad. I mean it has 120 miles on it.
I know I know I’m probably shooting myself in the foot

If the reservoir isn't full, start there. Completely full and stays full as you ride it (may burp out an air bubble). Make sure cap is fully seated. If that doesn't fix it, I'd check the thermostat. It's accessible by removing the primary clutch. I'd troubleshoot based on symptoms, not assumptions about parts being good because they're new-ish. But this sled should be covered under warranty?
My 18 over heats easily. Will the 20-21 thermostat work on a 18 ? The 20-21 thermostat is $50 cheaper so something must have been changed.
Yeah it's a direct replacement. I think Cat is just pursuing cheaper parts sources. The new cranks are way cheaper too.
