    Hello, recently purchased this 2015 Freightliner straight truck with Cummins engine ISB 6.7 - 280 HP.
    I am just wondering where exactly is the coolant temperature sensor located ? Here is the picture of the engine tag. Thank you.

    Front of the engine, passenger side in the thermostat housing. Where the upper radiator hose leaves the engine, it will be the two wire sensor right there.
