I suspect this overheat issue to be a bleeding issue as some came right from the factory improperly bled. My SW is the hardest sled I have ever owned to bleed all the air out of the system.
There also have been a few members that have had the plastic water pump impellor fail and spin inside the pump on the shaft. The impellor failure would def cause the sled to overheat quickly.
On my SW I have changed the impellor to the billet aluminum version from Dasa and I have also installed BOP's aux rad and fan kit.
I no longer have to worry about limp mode when waiting a long time to cross a road and or operating in low snow conditions.
