What's up guys!
Scion xD forum noob here posting a first post about a quick procedure for changing the spark plugs on a xD. I'm sure that most of you are explicitly aware of the process involved in this routine maintenance job but for those of you who are mechanically noobish then you may prosper from this guide
Helpful diagrams:
xD spark plug diagram <--under parts listing, click on the 'more info' button and a window will pop up with the diagram
1) Disconnect the negative battery cable.
2) Remove the engine cover.
3) Remove the ignition coils:
Detach the 4 ignition coil connectors.
Remove the 4 bolts (one bolt for each coil), and remove the 4 ignition coils.
4) Use a spark plug wrench to remove the spark plugs.
5) Inspect the spark plugs, most likely they are worse for the wear which is why you're reading this walk-through in the first place
To install:
6) Use a spark plug wrench to install and tighten the spark plugs to 14 ft. lbs. (19 Nm).
7) Install the ignition coil. Tighten the retainers to 80 inch lbs. (9 Nm).
8) Install the engine cover.
9) Connect the negative battery cable.
10) You're totally done!
