• Q: How to replace the Spark Plug Wires on 2002 Buick LeSabre?

  A: Users must begin replacements by turning off the Ignition Switch followed by removing the fuel injector sight shield. Start the procedure at the engine rear where you remove Spark Plug wires (2, 4, 6) from the spark plugs. Twist the Spark Plug boot by 1/2 turn, use the Spark Plug boot removal tool (J 38491) to gently raise the heat shield and subsequently remove the wires. Record the wires' positions before removal. Continuing with the Spark Plug wire installation, use the same procedures to guide the placement of wires 1, 3, and 5 at the engine's front section. Remove all ignition coils wires together before unfastening Spark Plug wires from the coils and engine-mounted retaining clips at both rear and front and top positions. During installation of new wires transfer required accessories including boot heat shields along with Spark Plug wire conduit and retaining clips. You should position new Spark Plug wires on the engine before installing retaining clips to link wires with ignition coils through front-to-rear mounting of Spark Plug wires (1, 3, 5) and Spark Plug wires (2, 4, 6). The last step requires the installation of the fuel injector sight shield.
