    I found a coolant leak under the cab on the driver side in between the driver seat and the sleeper mattress. It’s leaking on top of the fuel tank. Is that a heater core? Both hoses are leaking, so it doesn’t look like the hoses are damaged. This is on a 2014 Freightliner Cascadia DD15.

    Same Truck you just flushed and filled? At least you can turn off valve, nothing lost. Just when you thought it was all set for a while.

    One thing I've learned with owning a truck, you're never "all set for a while". As soon as one job is complete, another one makes itself evident.
