1. Disconnect the spark plug wire at each spark plug. ^ Twist the boots 1/2 turn before removing the boots. ^ Pull only on the boot or use a tool designed for this purpose in order to remove the wire from each spark plug. 2. Disconnect the spark plug wire from the distributor. ^ Twist each spark plug boot 1/2 turn. ^ Pull only on the boot or use a tool designed for this purpose in order to remove the wires from the distributor. INSTALLATION PROCEDURE NOTE: If the boot to wire movement has occurred, the boot will give a false visual impression of being fully seated. Ensure that the boots have been properly assembled by pushing sideways on the installed boots. Failure to properly seat the terminal onto the spark plug will lead to wire core erosion and result in an engine misfire or crossfire condition, and possible internal damage to the engine. 1. Install the spark plug wires at the distributor. 2. Install the spark plug wire to each spark plug. 3. Inspect the wires for proper installation: 3.1. Push sideways on each boot in order to inspect the seating. 3.2. Reinstall any loose boot. 3.3. Wire routings must be kept intact during service and followed exactly when wires have been disconnected or when replacement of the wires is necessary. Failure to route the wires properly can lead to radio ignition noise and crossfiring of the plugs, or shorting of the leads to the ground. 3.4. Any time the spark plug wires or boots are installed on the spark plugs, new dielectric grease needs to be applied inside the boot.

Condition General Motors has decided to conduct a Voluntary Emission Recall involving certain 2001-03 Chevrolet Silverado and GMC Sierra model vehicles, equipped with a 4.3L V6 (RPO L35 – VIN W or RPO LU3 – VIN X) engine. The ignition distributor cap and rotor in these vehicles may corrode and cause ignition system failure. This condition may result in rough engine idle, misfire, stalls, engine cranks but does not run and/or illumination of the Malfunction Indicator Lamp (MIL). Correction Dealers are to inspect the distributor ignition ventilation holes and, if necessary, replace the distributor cap and rotor, remove the External Ignition Protection (EIP) vent screens and install a foam sleeve around the A/C accumulator line. Vehicles Involved Involved are certain 2001-03 Chevrolet Silverado and GMC Sierra model vehicles, equipped with a 4.3L V6 (RPO L35 – VIN W or RPO LU3 – VIN X) engine and built within these VIN breakpoints: Service Procedure 1. Raise the engine hood and inspect the ignition distributor ventilation holes, located in the base of the distributor, to see if the External Ignition Protection (EIP) screens are present. 2. If the EIP vent screens are present: • Remove the vent EIP screens using the procedure listed in Step 3. • Refer to the appropriate procedure in the Engine Controls sub-section of the applicable Service Manual and replace the distributor cap and rotor. 3. Remove the vent screens (1), located in the base of the distributor, by inserting a plastic- handled, long blade awl or pick (2) into each of the two airflow vent holes and popping out the screen. If there are no EIP vent screens in the airflow vent holes, check the vent holes for debris and clear as necessary before reassembling the distributor. 4. If the EIP vent screens are not present, the distributor cap and rotor do not require replacement. 5. Install the foam sleeve, P/N 15190971, around the section of the A/C accumulator line that is routed directly above the distributor. Cut a slit in the sleeve and secure it to the line using tie- straps. Do not install a new foam sleeve if a sleeve is already in place on the A/C accumulator line. 6. 2001-03 CALIFORNIA, 2003 MASSACHUSETTS & MAINE VEHICLES ONLY : Install a Recall Identification Label. Also, for California vehicles, complete a “Proof Of Correction” certificate upon recall completion.

Tools Required J38491 Spark Plug Heat Shield Removal Tool 1. Turn OFF the ignition switch. 2. Remove the spark plug wires from the spark plugs. NOTE: ^ Allow the engine to cool before removing the spark plugs. Attempting to remove the spark plugs from a hot engine may cause the plug threads to seize, causing damage to cylinder head threads. ^ Clean the spark plug recess area before removing the spark plug. Failure to do so could result in engine damage because of dirt or foreign material entering the cylinder head, or by the contamination of the cylinder head threads. The contaminated threads may prevent the proper seating of the new plug. Use a thread chaser to clean the threads of any contamination. 3. Remove the spark plugs from the engine. Installation Procedure NOTE: ^ Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine. ^ Check the gap of all new and reconditioned spark plugs before installation. The pre-set gaps may have changed during handling. Use a round feeler gage to ensure an accurate check. Installing the spark plugs with the wrong gap can cause poor engine performance and may even damage the engine. 1. Measure the spark plug gap on the spark plugs to be installed and correct as necessary. Spark Plug Gap: 0.060 in (1.52 mm) NOTE: ^ Be sure that the spark plug threads smoothly into the cylinder head and the spark plug is fully seated. Use a thread chaser, if necessary, to clean threads in the cylinder head. Cross-threading or failing to fully seat the spark plug can cause overheating of the plug, exhaust blow-by, or thread damage.
