To ensure the correct firing order (1, 8, 4, 3, 6,
7, 2), the high tension leads must be replaced
in the correct relationship to each other (as
illustrated). Failure to maintain the correct plug
lead connections, will result in a misfire and
possible damage to the catalytic converter.
5,
Remove the plug leads, ensuring that you hold
the rubber shroud and NOT the high tension
leads (this will ensure no damage occurring to
the connectors during removal).
Ensure that the recesses around the plugs are
free from debris (to avoid foreign matter
accidentally entering the cylinder head) and use
a suitable spark plug wrench to remove the
plugs and washers.
When pushing the leads onto the plugs, ensure
that the shrouds are firmly seated on the plugs.
Refitting the plugs
When refitting, take care not to cross-thread the
spark plugs, otherwise costly damage to the
cylinder head will result.
Only fit plugs of a type recommended by the
vehicle manufacturer (see ‘ENGINES’,
page 241) and tighten to a torque of 15 lbf.ft
(20
Nm). Please note that incorrect grades of
plug may lead to engine failure and serious
damage.
