I'm about to replace all of my coolant hoses on my unimog 404. Since I'll be draining all of the coolant what is the recommend coolant to use in these motors?

It was my father in laws. He bought, it drove it around a few times and then got a fuel issue and never fixed it. I tried dragging it about 1 foot forward and didn't break loose. I was thinking of taking an impact gun to the rear hub bolt. Since they are torqued to 750 ft lbs, I could try...
