Overheating Plow Truck

theframer · January 10, 2011

My truck is a 2001 1500HD with a 7’6 Artic blade. The truck runs fine without the blade and even when the blade is installed it only overheats after the truck has been turned off then turned back on, turn it on again and it runs fine. I have replaced the temp sensor, thermostat, and still end up with the same problem, also I have noticed a relay seems to clicking under the dash. Or could it be a fan problem?

Thanks

I had over heating problems with my 03 2500HD. Did a little research and found others had same problem. The problem was with the thermostat, and GM came out with a revised new one which took care of the problem. With your thermostat when it was replaced, did you replace it with the same part number? Because the newer one has a different part number. If you replaced it with same part number, it will still over heat cause having a plow on, will cause this to over heat everytime. The entire part is a round metal dish that has cooling fins on it. I dont remmeber the # off hand, but google your truck and write "over heating when plow is on" and there should be a handful of sites with the correct part number.
