hello, I'm from Uruguay ( South América) and I have a problem with my deere . We're in wheat season and monitor says that exhaust temp is out of specifications, is while the auger is on or when I' m climbing a Hill . Last season I had no problem. Thanks for some help, I wish you could understand my poor english
J D 9770 exhaust temp.

Have a 9770. 1800 E. Hrs. Tier 3 motor.
Last season engine started running warm with that code. Day later electronic actuator and turbo packed it in. Was returning too much exhaust gas causing it to run hot.
This season ran up to hot. Foung EGR cooler got pin hole in it leaking coolant into cylinders. Burnt off coolant in the combustion process but eventually coolant ran low in a matter of minutes. Once engine turned off remaining coolant went through to sump when left overnight. Seems all this emission control stuff is quite unreliable in trucks, combines etc..
Hopefully a couple of things to watch out for.
