Estimated time: 30 Minutes |

1. Here are a
picture of the Tools I used to change the spark plugs. |
 |
|
2. I used NGK
Copper Plugs for my replacement. This is optional, the maxima is recommended
to run with Platinum Plugs, however copper provides a better spark and the
only down side is it will only last for 30k instead of 60k for platinum
plugs. The Nissan Part # for these plugs are 22401 - 50Y05. you can walk
into any Nissan Dealership and give them this part number for these copper
plugs. The NGK name for the plugs are NGK V-Power Copper BKR5E-11, all this
information was obtained from Bill from Maxima.org |

3. You will have
to remove the valve cover to access the front coil packs & spark plugs, the
valve cover is secured by 4 hex screws and can be seen on the graphic to the
right with red dots in them. |
 |
|
4. Use your 4mm
Hex Tool to remove the Hex screws from the valve cover. |
 |
|
5. Once the
Valve Cover is removed you will see the Coil Packs for the Spark Plugs, i
have numbered them 1 - 3 in the diagram to the right. Please note this is
not the order in the firing of the spark plugs, i just named them 1 - 3 for
illustration of location. |
 |
|
6. Use your
socket wrench and 8mm Socket to remove the Screws that are securing the Coil
Packs. A Phillips screwdriver is optional, however if the screws are pretty
tight, you can end up damaging the screw. A Socket Extention is recommend
but not required as it allows the job to be much easier. |
 |
|
7. Once the Coil
Pack Screws are removed you can lift out the coil packs. |
 |
|
8. Use your
Socket Wrench, Extension and Spark Plug Socket and remove the Sparkplugs
from the engine. |
 |
|
9. Here is a
picture of the Spark Plug removed from the engine. |
 |
|
10. Here is a
picture of the Platinum and Copper plugs side by side. |
 |
|
11. Here is
another shot. |
 |
|
12. Once you
have removed your old spark plug, you may now insert your new spark plug
into the engine. The FSM suggests 14 - 22 ft lbs for torquing the Spark
Plugs. If you don't have a torque wrench i have found a method that works
for me, please don't do this unless you want to, i will not be reponsible.
The method i use is, once the plug becomes snug, i then make one full 1/4
turn with the wrench. Again do this at your own risk. |
 |
|
13. Once you are
done tightening up your new front plugs re-insert your coil packs. |
|
|
14. Use your
Socket Wrench and 8mm Socket to tighten up the coil packs to make them
secure. |
|
|
15. One you have
tighten all your coil packs you are ready to put back your valve cover. |
|
|
16. Use your 4mm
Hex Tool to tighten up your valve cover and now you are ready to do the rear
plugs. |
|
|
17. The rear
spark plugs are located towards the back of the engine inbetween the intake
manifold. As you can see on the right. Once again i have numbered them for
illustration and not for firing order. |
 |
|
18. Use your
socket wrench and 8mm Socket to remove the Screws that are securing the Coil
Packs. A Phillips screwdriver is optional, however if the screws are pretty
tight, you can end up damaging the screw. A Socket Extention is recommend or
an 8mm deep socket. Becareful with these screws as they can get lost in the
engine real easily. |
 |
|
19. The Coil
Pack to the driver side of the car is very hard to get to and will require
you removing two nuts to get to it. The first one i have labeled "1". You
will now use your 12 mm Deep Socket to remove this Nut. |
 |
|
20. Here is a
picture of the Second Nut label "2" |
 |
|
21. To ensure
that you don't mix up coil packs when you are replacing the rear plugs, put
them in order as they would go in the Engine, I have labeled 1 2 3 on the
Engine Location and 1 2 3 on how it appears where i have put them
temporarily. |
 |
|
22. Use your
Socket Wrench, Extension and Spark Plug Socket and remove the Sparkplugs
from the engine. |
 |
|
23. Once you
have removed your old spark plug, you may now insert your new spark plug
into the engine. The FSM suggests 14 - 22 ft lbs for torquing the Spark
Plugs. If you don't have a torque wrench i have found a method that works
for me, please don't do this unless you want to, i will not be reponsible.
The method i use is, once the plug becomes snug, i then make one full 1/4
turn with the wrench. Again do this at your own risk. |
 |
|
24. Once you are
done inserting your new plugs. Use your 8mm Socket / Extension and Socket
Wrench to replace the rear coil packs. |
|
|
25. Use your 12
mm Deep Socket / Socket Wrench to tighten up the two Nuts near the last coil
pack. |
|
|
26. Now you have
replaced your Spark Plugs. |
