Vehicle Damage Warnings

SPARK PLUG and SPARK PLUG WIRES

CAUTION: Spark plug wires must be connected to the proper ignition coil terminal. Mark spark plug wire locations before removing them.

CAUTION: Be sure to orient the spark plug boots so the spark plug wires do not contact the exhaust manifold shields or steering gear intermediate shaft. Wire contact can send voltage spikes to other electronic modules.

NOTE: Apply Silicone Dielectric Compound D7AZ-19A331-A or equivalent meeting Ford specification ESE-M1C171A to the inside of spark plug wire boots.

CAUTION: Do not drive the vehicle with spark plug wires disconnected. The result could be damage to the catalytic converter.
