    Q:
    How to replace the Spark Plug Wires on Buick Lucerne? Posted by Customer
    A:
    Begin the wire Spark Plug replacement process by taking off the intake manifold cover first. Separate the left side Spark Plug Wires from their connections to both spark plugs and Spark Plug coil. Before changing a single plug wire users should unlock their retaining clips before removing the wire. Start by dislodging left side Spark Plug wire clips from both the intake manifold bracket and heater inlet and outlet pipe before you extract the Spark Plug wire assembly. Inspect both Spark Plug Wires as you disconnect them from their respective spark plugs and Spark Plug coil while removing the clip from the Spark Plug coil bracket and extracting the assembly from the coil bracket. Start by placing the Spark Plug wire assembly into position then fasten the right side Spark Plug wire clip onto the Spark Plug coil bracket. When replacing one plug wire only, simply install it and terminate the retaining clip. Connect the Spark Plug coil to both right side spark wires and spark plugs before putting the Spark Plug wire assembly into place. Reinstall the left side Spark Plug wire clips to their positions at the intake manifold bracket and heater inlet and outlet pipe. Also replace any remaining single plug wire replacement before securing all clips. To finish the procedure connect both left side Spark Plug Wires one after the other to the Spark Plug coil and spark plugs and reinstall the intake manifold cover.
