I hit 121 deg c with mine while 4 wheeling this wknd....that is 249 f.
Called 3 dealers all said no problem....if light for check eng did not come on....
What are your thoughts...service reps are not mechanics but that is what I was told???
ran 112 most of way in on fields (pheasant hunt) then hit 121 once so I shut it down....on way back on my trail (2 miles across fields) it ran 105.....
Had I not had this option I would not know temp....oil does not smell burnt...and have run my 03 ram this hard before...but happen to hit vehicle info as I knew I was working the truck but did not feel it was excessive...it is a 2010 ram 5.7 l auto with 8oookm
