Let a bunch of air out of those tires!!!! For sand use 4hi lock, turn off the StabiliTrack. Tires should be less than 20 psi, I run mine at 15 psi.
When you run with street pressure, you are working the engine much harder. Sand also saps power, power makes heat!

Get a little compressor and check it out aired down.................like night and day.

Yesterday I ran the truck on sand for1 minute at full throttle, 5-6k rpm, using the 4low, the engine temperature was on red at full. Is it normal? I checked the coolant level, was ok.

Any ideas?

Thanks in advance

That's like hitting your own leg with a sledgehammer and wondering if it's normal that your bones broke.......
