aWhen refitting the spark plug wiring, always apply a
bead of FLUOSTAR 2L (2 mm in diameter) to the in-
ner edge of the high-tension caps on the side of the
spark plugs and coil.
aConnect:
-the ignition coil connector,
-the ignition coil high voltage wiring harness.

aIt is essential to apply a bead of FLUOSTAR 2L
(see Vehicle: Parts and consumables for the re-
pair) (04B, Consumables - Products) with a diame-
ter of 2 mm to the inner edge of the high tension
caps on the spark plug and ignition coil side.
II - REFITTING OPERATION FOR PART
CONCERNED
aRefit the spark plugs.
aTorque tighten the spark plugs (23 N.m) using the
(Ele. 1933) fitted with the (Ele. 1382-01).
III - FINAL OPERATION
aConnect the ignition wiring harnesses to the spark
plugs.
aRefit the air filter unit (see 12A, Fuel mixture, Air fil-

WARNING
Do not use any product designed to improve the
electr ical contact in the injection computer and oxy-
gen sensor connectors or on the bodies of the oxy-
gen sensors.
Failure to respect this advice causes the oxygen
sensor to malfunction and results in failure to com-
ply with the emission control standard.
WARNING
If the connections are corroded, repair the wiring
(see Wiring: Precautions for repair) (Technical
Note 6015A, 88A, Wiring).
