2007 Pontiac Wave Base, 4D Sedan, D16/MLMSECTION Installation ProcedureSpark Plug Inspection
- Install the spark plug wire on the coil (2).
- Install the spark plug wire (1) at each spark plug.
- Inspect the wires for proper installation:
- Push down on each boot in order to inspect the seating.
- Reinstall any loose boot.
- Wire routing must be kept intact during service and followed exactly when wires have been disconnected or when replacement of the wires is necessary. Failure to route the wires correctly can lead to radio interference and crossfire of the plugs, or shorting of the leads to the ground.
- Any time the spark plug wires or boots are installed on the spark plugs, new dielectric grease needs to be applied inside the boot.
- Install the engine cover on the engine.
Tighten: Tighten the engine cover bolts to 3 N.m (31 lb in).
NOTE:
If the boot to wire movement has occurred, the boot will give a false visual impression of being fully seated. Ensure that the boots have been properly assembled by pushing sideways on the installed boots. Failure to properly seat the terminal onto the spark plug will lead to wire core erosion and result in an engine misfire or crossfire condition, and possible internal damage to the engine.
