Again clean the oil cooler and the radiator. I the transmission cooler and hydraulic cooler are usually air cooled . So they have no effect on overheating unless they are blocking the radiator air flow.
That would be for a new radiator operating at absolutely peak efficiency. On this machine any difference beteween top and bottom hoses of around 15F would be acceptable I think.If the radiator is working correctly, I think there's supposed to be 20F difference between top and bottom temps
Make sure to take pics Shawn, for the benefit of us all in the future !Delmer, you have an excellent course of action that doesn't cost any money. Nige, I love the way you dig up the spec's! I'm exhausted... they're picking up the skidder. Shucks.... Foot Doc tomorrow. Top and bottom split, good check on efficiency! Take off the grill and clean the fins. Temp gun should work in sections from the front. The engine oil cooler should show a good in and out temp split too. You guys are giving me some Great Clues!! Now for some dinner. That bed is already looking Good! I haven't worked this hard since I retired!!!
Cheers

We had this same issue on a loader only used for snow. Tried backflushing, chemicals etc. with no luck. Our bush fix was cut a hole in the top of the radiator and rod it out. Then make a cover and tap the radiator for bolts to hold it in place. It had to be cleaned on three separate occasions until it wouldn't overheat. We used an electricians wire fish for rodding. I think we doubled up the fish for better cleaning. We also stuck a big magnet in there to catch the rust.If you want to try to flush it yourself, remove the cap and both hoses, stick a running garden hose in the top, stick a rag and air blow gun in the bottom, once it overflows give it a little shot of air, repeat until you get no more sediment, giving bigger shots of air as you progress. Clean the oil cooler like TCT has said. Could run it with rainwater a few times for a few hours each, and repeat until there's no more sediment in the drained water. You don't need good circulation, barely any circulation at all will be plenty if you're operating this thing only in winter.
