    I hope it's instrumentation. That is a super high coolant temp to have no other signs or symptoms. I don't wanna scare you anymore then you probably are, but those temps will ruin the linings in the cylinders, warp the head, and straight up melt cam bushings. Please be very careful, if you have warranty time left don't waste anymore of it.

    Rush is in Fontana...Cummins is in Bloomington...Real close to one another...
    I took my 379 to Rush before...They had it a week...

    Cummins usually can knock out most projects in two days...

    You can go to j and r they will knock it out in one day. There in bloomington. Cummins is just down riverside have. But ifwant warranty work its got to go to cummins and they will never start on it tommorow. Sat day is day they get everything out that was promised on Wednesday.Your chances on them starting on it tommorow are about as good as a blind man playing scrabble with gypsies. Not good.

    Well some good news...I went back and checked the oil and the coolant...
    No coolant in the oil and in fact...The coolant level is the same as it was yesterday on my Pre-trip.

    So if it is the coolant pump...How can the coolant be at between 180-190* with the oil temp at 230*?

    Oil pressure btw, is between 30-35 PSI...
