EXAMPLE
• When disconnecting the spark plug
cables, pull on the boot, not on the
cable itself. Pulling on the cable can
damage it.
• When installing the spark plugs,
screw them in with your fingers to
avoid stripping the threads. Tighten
with a torque wrench to :
Alto - 13.0–22.0 N-m (1.3–2.2 kg-m,
9.4–15.9 lb-ft)
Alto K10 - 25 N-m (2.5 kg-m, 18.0
lb-ft).
Do not allow contaminants to enter
the engine through the spark plug
holes when the plugs are removed.
• Never use spark plugs with the
wrong thread size or length.
CAUTION
When replacing spark plugs, you
should use the brand and type
specified for your vehicle. For the
specified plugs, refer to the
“SPECIFICATIONS” section at the end
of this book.
NOTE:
When installation, make sure the wires,
couplers, sealing rubber of top cover and
washers, are correctly returned in place.
