REPLACING SPARK PLUGS
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.
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 log shown in the “NISSAN
Service and Maintenance Guide”. Do not service
platinum-tipped spark plugs by cleaning or re-
gapping.
cAlways replace spark plugs with rec-
ommended or equivalent ones.
1. Remove the engine cover (QR25DE en-
gine) .2. Disconnect the ignition coil connectors. Re-
move the ignition coil bolts.
3. Disconnect the ignition coils from the spark
plugs.
4. 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.
5. 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)
6. Holding the boot, reconnect each high ten-
sion cable/ignition coil to its proper spark
plug by pushing it on until you feel a snap.
7. Install the ignition coil bolts.
Ignition coil bolt tightening torque:
33 - 44 in-lb (3.8 - 5.0 N·m)
Connect the ignition coil connector.
8. Install the engine cover (QR25DE engine) .
