Installation guide - Replacing spark plugs / ignition coils
General guidance for this part type - always follow your device manual- Spark plug socket, extension and ratchet
- Torque wrench
- Small pick for connector clips
- One cylinder at a time keeps coil wiring in the right order.
- Oil in a plug well points to a leaking valve cover gasket.
- 1Let the engine cool. Switch the engine off and let it cool fully; plugs removed from a hot aluminum head can strip its threads.
- 2Remove one coil. Work on one cylinder at a time. Press the connector clip, unplug it, undo the coil bolt and pull the coil straight out.
- 3Swap the plug. Blow dirt out of the plug well, unscrew the old plug and check the new plug's gap against your service manual.
- 4Fit by hand first. Thread the new plug in by hand for the first turns to avoid cross threading, then tighten to the value in your service manual. Refit the coil and connector.
- 5Repeat and test. Do each cylinder in turn, then start the engine and check for smooth idle and no warning light.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
