I have a friend with a John Deere 270D excavator that has about 4000 hours on it .Machine no older than two to three years old.It over heats after about ten minute of hard working .Had the dealer out and can not find out why it happens.They took a temp read on the top and bottom of the radiator ten degree differnce.Is that normal ont htis unit.If you let it idle every thing goes back to normal.Unit has a new thermostat,coolant ,cooolent temp sender,fan belt is tight .And radiator and oil cooler are clean on the fins .I told him to llok betwwen the two and double check.It has a hydrualic driven fan.I thought maybe the cores are getting clogged in the radiator slowing the flow down .I asked does it hace coolant filter .He was going to check.Any other thoughts on this .The machine is Washington DC so I can not go and look at it.But would like to see happen to try to figire it out .
