Overheating Plow Truck

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.

turns out the clutch fan needed to be replaced works great and is back plowing snow! :confused:

 

 

Yes, that is what was replaced on mine, the clutch fan. Sometimes my memory isn't so sharp of exact parts replaced.

    • Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?  
    • I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery. 
    • The lifter issue can be dealt with by shorter oil changes and quality oil IMO.
    • Got heavy rain, hail and light rain yesterday. 
    • I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
