CMV Posted August 5, 2015 Report Share Posted August 5, 2015 So my alternator went out and I changed it this past weekend. What a joy that was....... Anyway, after R&R the radiator to get to the alternator the DIC says check coolant level. I reset codes and it keeps coming back. Level in overflow tank is correct, temp gauge seems to work properly and holds at about halfway once the engine is hot, and I don't see or smell any coolant leak. What did I screw up to trigger this? It was a frustrating chore getting stuff out of the way to access the alternator and equally frustrating getting it all back in place. But I don't remember unplugging or even seeing anything that would be a coolant level sensor. 2 fan pigtails, outside air temp sensor (i think - mounted on hood latch supports), harness at alternator, and battery are only electrical connections I remember messing with.
