Greetings Team
I am a little concerned about my GU overheating in the soft sand. Couple days ago I was over on the north shore and driving through soft sand but it was not that soft and just normal 4h was needed. Tires was dropped down to around the 19 mark and I noticed that the temp meter went up very high. I then turned the aircon off and all went back to normal......
On the way back I had to pull this bloke out of the first cutting with a camper and that was some hard work for the Patrol and the temp started climbing again and very fast. When I got
home I checked oil and water and all seemed okay
This never used to happen and is a new thing. I have done allot of soft sand driving and towing cars out in the little truck.......Any ideas??

G'day mate,
What motor do you have? I checked your Rig Profile etc, but it doesn't say what donk.
Anyway, in my case, I have never noticed the temp go up when sand driving......but I always ALWAYS use low range when driving in sand.....even did the whole
Simpson Desert crossing from Big Red to Purnie
Bore in low range. Temp guage sat on normal/85oC the whole time.....and that was towing the camper trailer etc. I kept revs to around the 2000 to 2500 mark. The issues I've had with my temp guage are VERY
WELL documneted on here, but slow slogging in sand is never a problem.....only high speed and
hill climbing etc.
I would also mention that i let my tyres down to 16psi for sand work....always.
Cheers
Roachie

It's really a matter of going through the basics. Do the inexpensive things first unless there is anything obviously wrong. Clean the radiator and descale the cooling system.
Check thermostats, fan hub, hoses for any softness (especially lower radiator one, which can collapse and block off).
Check engine tune, exhaust restrictions. If the oil gets filthy, sludging can restrict oil flow under pistons, which is essential for cooling. If so, that would require flushing the crankcase.
People often spend $3000-$4000 by just doing all the major items first, only to find that a lot of their money is wasted. If it has got worse since new, some part of the system is failing. A big core radiator may over ride the issue, but not correct it.
Hope these comments help.
