Anyone replace the coolant on their QSM11s? Mine was last done 5 years/500 hours ago, when Cummins did some warranty repair that required the coolant to be drained. My records show about 8 gallons of coolant per engine, using the Fleetguard CC2825 blue coolant. The product info page for the coolant says 4000 hour service life, the QSM 11 service schedule says replace it every 1500 hours, mechanic says every 3 years, 5 tops.
I believe there are test strips the measure the health of the coolant, but mechanic says dont bother, just replace it.
Opinions?
