I have a 2001 763G. It runs great. After using it for 30 minutes or so in 90 degree weather it starts getting hot. The temp gauge goes to the yellow and approaches the red. Today it did get nearly to the red and the temp light came on. I can let it idle or run for a few minutes without using the hydraulics and it cools right back down. I have only used it for a very few hours. I bought it several months ago, but not used it a lot. It sounds like the Hyd. are noise when steering. It is full of hyd. fluid and all fluids are full (rad. engine oil) I have not independently checked the actual coolant temperature, but with the light coming on seems to confirm the overheating Any suggestions? Thanks Larry
