    ECT2 above critical (EWPS programmable limit)
    Something to do with coolant temp or level??? Although gauge is saying its normal.

    Red warning indicator, dash only says stop engine and truck shuts itself down.

    If you have a Maxxforce engine, it has two separate coolant temp sensors. ECT1 is the main temp sensor and the sensor used for your gauge. ECT2 is basically for the egr cooler systems. If you have a Maxxforce 13, it uses a separate coolant control valve to direct coolant through its own separate radiator. Probably have a failed valve and coolant isn't flowing through and over heating.

    I think it was probably just past due. Haven't been in this truck very long and it maintenance history is a black box (not my truck). Nothing seized up, everything spinning fine and no uneven wear or anything strange on the pullies or tensioner so I think it was just old. 534k on the truck and for all I know it could have been the original belt.
