2007 D16. Overheating /Shutting Down

I shift

 

Coolant temp sensor maybe.... But most likely your egr temp sensors with the little computer box is causing the code as it sees the heat from egr after the EGR cooler....which could be a sticking EGR valve allowing excessive flow and coolant temp overload.
Excessive EGR flow results in a cracked cooler in short order...you want to avoid this costly repair!

 

Change your oil it will stop shutting down going up an incline
If you are loosing 1/2 gallon of coolant every 2500 to 3500 miles clean your egr cooler

 

What temp is the Rad. cooling fan turning on at, poss. not soon enough to stop over temp shut/down?

 

^^ good question!

 

Does the truck pull well is my first question then the second question i have what is the oil temp and oil psi when the oil can comes on the dash along with the engine shutting down. also does the fan come on often there is a good possibility the radiator fins are plugged with just debri and it's not cooling the system down like its supposed to. also if you have codes for an egr temp usually that comes with a good derate of the engine it can happen for a few different reasons one being that the vgt its getting stuck or epg the second egr cooler needs to be washed out.

 

A wise choice!
