Spark plugs - V8 engine
Replace
Take great care when fitting spark plugs not
to cross-thread plug, otherwise costly
damage to cylinder head will result. It is
essential that correct grade of spark plugs
are fitted. Incorrect grade of spark plugs
may lead to piston overheating and engine
failure. Use only approved spark plugs, use
of unapproved spark plugs may cause the
misfire detection system to malfunction.
1.Disconnect battery earth lead.
2.Noting their fitted position, disconnect ht leads
from spark plugs.
3.Remove 8 spark plugs.
4.Ensure that gap of new spark plugs is 1.0
±
0.05 mm (0.040
± 0.002 in).
Do not attempt to clean or adjust gaps. If a
spark plug problem exists, try substituting
defective spark plug(s) with new one(s).
CAUTION: Do not attempt to clean or adjust
spark plug gaps. If a spark plug problem
exists, try substituting the defective spark
plug with a new one.
5.Fit spark plugs and tighten to 20 Nm (15 lbf.ft).6.Connect ht leads to spark plugs.
7.Connect battery earth lead.
