Volvo Repair: spark plugs, volvo s70 glt, 1998 volvo s70 glt

Question
Can you walk me through changing the spark plugs for my 1998 Volvo S70 GLT.
I don't recognize the cover assembly that covers the plugs or what to do to remove it.   Thanks

Answer
it is the long black cover on top of the motor.it is held on with 8 torx 30 screws.rmove the screws and then you will need to remove the 10mm bolts holding each coil to the head.then you can pull them out to get to the plugs.I would number the coils so they do not get mixed up when putting back on.
