Changing out all 4 EGT sensors, is there a down side ?
My 2011 KR 6.7 is coming up on 100k miles, I am getting paranoid of an EGT sensor failure while I am in the middle of "nowhere". I haven't had a single problem with the motor, so I don't mind spending the money for the sensors, as I would install them myself. Am I correct in believing it's not a matter of "if" but "when" these sensors go bad ? Thanks.

Be careful as lynnmor mentioned. They are known to be quite troublesome to remove after so many heating/cooling cycles. the problem for me, is that a flarenut wrench doesnt get the best bite, and the only way to get a socket on it is to cut the top of the sensor off at which time you are committed to your project. If you put too much torque on them, the bung they thread into has been known to twist right off the exhaust making the situation much worse.
if it were me, and not having any problems, I'd get the latest calibration, and keep on driving. No sense in making a preventative maintenance repair go south....

I completely agree, I've had a spare EGT sensor in my glovebox for about 5 years and haven't needed it till recently. 105k miles and it was the first EGT sensor failure. The new programming no longer shuts down the truck so it's not a huge deal and can be changed at your convenience. I soaked mine with PB Blaster, let it soak for an hour and it came right out.

By now you should have removed each sensor, cleaned the threads and applied high temperature nickle anti seize. I keep a code reader, a 13mm wrench and a spare sensor in the truck in case of a fault. You should have the latest software update to prevent total shut-down from a sensor going haywire. If you have the update, it is no big deal, just drive till you can get it fixed.
