2025 western star 47x Overheating

Bear with me as I’m still learning and not very experienced with trucks but am trying to gain more knowledge. Along with seeing if there could potentially be something wrong or if it’s just a truck we are gonna have to fight constantly.

I work on a feedlot in Oregon feeding cattle mainly with a 2025 western star 47x. We are having constant issues with the truck overheating along with the truck not being able to handle loads above 20,000lbs(not including the box added to mix cattle feed) without it constantly trying to die on us. Now mind you the feedlot mixer box that got added to the truck before it came to us can weight from 16,000lbs-23,000lbs. Not entirely sure on the weight, but most likely closer to 20,000lbs. Within the feed box, there are added augers that pull power from the truck to mix the feed. Our load sizes can range from 1,500lbs- 29,000lbs. Depending on the ration. After we get the feed mixed and are heading out to feed the cows, it’s a constant battle keeping the truck from dying on us when trying to feed with loads above 20,000lbs(some days even 15,000lbs is to much) We have to turn on the augers to be able to spit the feed out of the truck otherwise the feed won’t come out. It does struggle to get up and drive off when it gets loaded but the dying part comes in when we try to feed and turn the augers on.

Now the other issue is the overheating. We are having constant overheating issues. It is dusty but we are blowing out the radiator and all that constantly. Trucks get mandatory blown out once a day and we’ve been blowing out this truck 2-3 times a day not including end of the day servicing. Truck gets daily checks on fluids and what not. It’s not overheating when doing one thing. It sometimes overheats well we are getting loaded with the augers and pto engaged. Sometimes over heats well we are driving or feeding cattle. So it’s not only one thing that is causing it to overheat. It’s anything we do with the truck. It’ll even over heat when doing small loads that are less than 15,000lbs. Filters get checked regularly, servicing is done regularly etc…. We’ve had these issues since we got the truck with less than 100 miles on it. Apparently it was tested on a feedlot and did fine but we are having constant issues.

Any ideas? Maybe a case of it is what it is?
Feel free to ask questions as I may have forgotten something or made things unclear.

 

Yes it is boiling over. It’s shut down on employees before. I can look to see what engine it is but don’t know off the top of my head. Engine fan is switched on
