Accent GT Coupe L4-1495cc 1.5L DOHC MFI (1997)
Tightening torque : 20-30 N.m (204-306 kg.cm, 15-21 lb.ft).
ANALYZING SPARK PLUG
Engine conditions can be analyzed by the tip deposits near the electrode.
SPARK PLUG TEST (WHEN ENGINE CAN BE CRANKED)
Connect the spark plug cable. Ground the outer electrode (main body), and crank the engine. In the atmosphere, only short sparks are produced because
of the small discharge gap. If the spark plug is good, however, sparks will occur in the discharge gap (between the electrodes). In a defective spark plug,
no sparks will occur because of a leak through the insulation.
