    where is this coolant temp sensor located - 2014 Diesel

    Trying to find this sensor on the daughter’s 2014 Cruze Diesel.
    ACDELCO 55591401 COOLANT TEMPERATURE SENSOR


    goldcruzetempsensor


    The problem is that the temp gauge does not ever show any reading.
    We installed a ScanGauge-II, it reports 40 degrees at all times.


    So I bought the easy to find and replace green sensor NTK EF0067, will replace that to see if the temperature starts working again.


    greencruzetempsensor


    But can’t find where the other gold 90 degree one is. Searched and found where it is on a 2016, but notes said it is in a different location on the 2014 - any ideas?


    Thanks,
    Frank

    The green one is the engine coolant temp sensor that mounts near the thermostat.

    The gold slip in style one is a radiator temperature sensor, or sometimes engine coolant temp #2, if your car has it it's on the passenger side end tank of the radiator.about halfway down. Near the hose

    Since there were no Diesels produced for 2016 (2014-15 gen 1 and 2017-19 gen2), you might mistakenly found a diagram for a gasoline 1.4L instead of a 2.0 Diesel. (unless the 1.4 and 2.0 share a radiator and sensor...)

    We just completed replacing the green one, now the SCANGUAGE-II says it is 114 degrees, instead of 40 degrees, as before with the original (broken) green sensor!
    (It is 93 outside here today)
    Still no reading on the dashboard temp gauge, but it might not display any reading until the engine gets to ??? 150 ???
    Anyway, my daughter can use her SCANGUAGE to keep track of the temp now!!!

    If it's 93 outside, 2 minutes of driving should get the gauge to come off the bottom. Any update on if the cluster gauge works now?

    Also, good to replace this as you did since the ECM needs to know the engine temperature to help fuel delivery.

    It turns out that my daughter had the SCANGUAGE set to read air intake temp, so 114 makes sense now.
    When she sets it to read coolant temp, it still says 40 degrees.
    So we have no idea what the $55 green sensor does.
    If it is providing data to the ECM, great. But the original one probably was not defective anyway.
    We are still looking for the $7, gold, "right angle" sensor , that one might operate the dashboard temp gauge.

    Plan "C":
    If I can't find or access the other sensor so the stock gauge can be made to read again, we can add a temperature gauge somewhere in the dashboard area.
    Is there anywhere in the cooling system plumbing that has a plug to remove or place I can drill & tap for a manual temperature gauge ?
