Towed the skidloader today for 50 miles at 12,000 lbs and the temp never ran over 100 degrees, you'd think the sensor was bad. Let it idle for 20 minutes and it goes up to 150, end of story. Never thought the cooler had that much effect in the winter. Don't have a cover over the front and water temps were at 180, even when pulling hills. Temp was 34 today. DW
