8) Swap Spark Plugs
1) One you have removed the Ignition
Coil , check for any dust / dirt in the hole. If you see any (I had quite a bit
dust) use a dust blower to blow it out or a narrow vaccum cleaner extension, or using a drinking straw attached to the vaccum cleaner hose.
Note: Blow out the dust before you remove the Spark Plug!
Next use the Wrench with
the extension bar and the Spark Plug Socket 10mm to remove the Spark Plug. You might want to use some tape to fix the socket to the extension bar, as the socket has a rubber cushion in side it and normally attaches itself to the Spark Plug and when you pull the bar out, and stays in.
As the car is
cold the Spark Plugs may be really tight,
if so, then you could start
the car and let the engine warm up a bit, this will loosen the
tight Spark Plugs and you should be able to remove them easier, but then you may burn yourself while changing them...so be careful!
Remove the old Spark Plug
3) Next place the new Spark Plug into Spark Plug Socket and then lower it down into the hole. Tighten the
Spark Plug to a hand tight finish - meaning just keep
turning it till you need to apply some pressure, at which point
Next ighten the Spark Plugs using either of the tools and methods:
Using a Torque Wrench, tighten the Spark Plug to 30nm (as specified on the box of the NGK Spark Plug)
2) Or using a Socket Wrench and give the Spark Plug a final tight 90 degrees turn (as
specified on the box of your Spark Plugs which
depends on the seat of your Spark Plug). Do not under or over tighten the
Spark Plug, this may have an effect on engine performance.
