    Holden 186 Motor

    The Holden motor in Gilbert, 77 series 3 SWB
    What is the black canister for. I think its to do with the Holden motor.
    Maybe a breather of some sort.
    Thanks.

    The black canister is normally a charcol filter.
    Filters the petrol fumes from the carb etc.

    I could be wrong

    Thanks for the replies.
    Next question regarding the Ignition Coil.
    I have no spark.
    So with the ignition on, I had 12.5 ( same as battery ) on the + side of the coil, the wire coming from the ignition switch.
    12.5 on the - side of the coil, which goes to the points. 12.5 at the points.
    Using the ohms scale at its lowest, got.
    Primary,
    - to + 2.4
    + to - 2.4
    Secondary,
    +to HT, 1 on the left hand side of the screen.
    - to HT, 1
    The NOS coil reads the same on the primary, 2.4, and but 9.55 on the secondary. But still no spark
    Do these readings seem ok for the New coil ????
    I will put new points in tomorrow, and see if things improve.
    What points gap would be good for the 186 motor.
    The old coil read USE WITH RESTSTOR, so does the one I replaced it with, but I cannot see one inline, unless its hidden behind the dash somewhere.
    Any Thoughts.
    Thanks

    0.5mm roughly for the points
    If the engine ran before with the original coil then there must be a resistor or resistive wire in the circuit.
    because your getting 12v to the coil would mean that the resistor, if it is there is still intact.
    could be the condenser as well causing problems.

    If the coil says use with resistor, and you don't use a resistor, your points will burn out much quicker than normal.

    Hi,
    Have had the Holden 186 running real smooth at idle.
    Ran a cleaner through the water system, after finding the Top hose was gunked up to the thermostat.
    Where is the water temp sensor, on my 186 ????
    Can you tell me the year of the motor from the serial No ????
    should I replace and put back in a thermostat ????
    First start up seems hard. Fuel seems to be draining back to tank from pump. Glass bowl fills during cranking, but needs a drop of fuel down carby to start. Will change the inline fuel filter tomorrow.
    Any ideas on this ????
    Thanks for the comments.

    You need a thermostat for correct engine temp.
    Your fuel problem is most likely the fuel pump not holding pressure overnight so new pump should fix.

    Temp sensor I thought was on the head, it's been a long time since I have even seen a holden 6
