REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-tipped
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance schedule, but do not reuse
the spark plugs by cleaning or regapping.c Always replace spark plugs with rec-
ommended or equivalent ones.
WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect socket
can damage the spark plugs.
QR25DE
1. Disconnect the negative battery cable.
2. Remove the engine cover.
3. Remove the coil pack bolt.
4. Remove the coil pack/spark plug boot from
the spark plug.
5. Remove the spark plugs with a spark plug socket.
The plug socket has a rubber seal that holds
the spark plug so it does not fall when it is
pulled out. Make sure each spark plug is
snugly fitted into the spark plug socket. 6. Fit the new plugs, one at a time, into the
spark plug socket and install them. Use
only the specified spark plugs. Turn
each plug several full turns by hand, then
tighten with the spark plug socket to the
correct torque. Do not overtighten.
Spark plug tightening torque: 14 - 22 ft-lb (20 - 29 N·m)
7. Install the coil pack/spark plug boot on the spark plug by pushing it on until you feel a
snap.
8. Install the coil pack bolt. Coil pack tightening torque: 48 - 65 in-lb (5.4 - 7.3 N·m)
9. Install the engine cover.
10. Connect the negative battery cable.

NISSAN dealer for assistance.
