I have a 2008 650j with 4800 hrs. Will run it bout 2 hrs and the hydraulic high temp light comes on, let machine cool for 15 minutes and can get about 2 more hrs and light comes on again. I have cleaned/ pressure washed radiator till it's like knew, changed filter, and this last time took valve body off and had tested. Shot with temp gun when light came on - valve body 220, tank 210, pump, 210, hottest cylinder 190, oil cooling side of radiator bout 160. Transmission side of Dozer/ tank runs 150-160. Any help would be greatly appreciated. One last question is there a screen/ filter inside the tank?
