PLATINUM SURFACE SPARK
8D - 4 IGNITION SYSTEM
DESCRIPTION AND OPERATION (Continued)
2.5L SPARK PLUG GAP MEASUREMENT
CAUTION: The Platinum pads can be damaged dur-
ing the measurement of checking the gap if extreme
care is not used.
• Use only a taper gap gauge (Fig. 3)
• Never force the gap gauge through the platinum
pads. Only apply enough force until resistance is felt.
• Never use a wire brush or spark plug cleaner
machine to clean platinum spark plugs
• Use an OSHA approved air nozzle when drying
gas fouled spark plugs.
If gap adjustment is required of platinum plug,
bend only the ground electrode. DO NOT TOUCH
the platinum pads. Use only a proper gapping tool
and check with a taper gap gauge.

CAUTION: Cleaning of the platinum plug may dam-

SPARK PLUG CABLES
secondary ignition wires. They transfer electrical cur-
rent from the distributor (2.5L), coil pack (2.0/2.4L),
to individual spark plugs at each cylinder. The resis-
tor type, nonmetallic spark plug cables provide sup-
pression of radio frequency emissions from the
ignition system.
contact at the coil and distributor cap towers and at
the spark plugs. Terminals should be fully seated.
The nipples and spark plug covers should be in good
condition. Nipples should fit tightly on the coil and
distributor cap towers and spark plug cover should
fit tight around spark plug insulators. Loose cable
connections can cause ignition malfunctions by per-
mitting water to enter the towers, corroding, and
increasing resistance. To maintain proper sealing
at the terminal connections, the connections
should not be broken unless testing indicates
high resistance, an open circuit or other dam-
age.

for brittle or cracked insulation.
