Maintenance service adjustments must conform to specifications contained in the Engine/Emissions Diagnosis* manual, to those listed in the Truck Performance Specifications Book or shown on the Vehicle Emission Control Information Decal which is located on or near the engine (Fig. 1), or the emissions systems may become inoperative.

If an engine is equipped with a "Dura-Spark" ignition system and any high tension ignition wire was detached from a spark plug, the distributor cap, or the coil to perform

a maintenance operation, Silicone Dielectric Compound (D7AZ-19A331-A, [ESA-M1C171-A] or equivalent) must be applied to the boot before re-connection. Using a small clean screwdriver, apply a thin layer of Silicone Dielectric Compound on the entire interior surface of the boot.

As a safety precaution, before starting the engine to perform maintenance, make sure the transmission selector is in PARK (Automatic Transmission) or NEUTRAL (Manual Transmission), the parking brake set and the wheels blocked.
