Cleaning and Inspection
NOTE: Several unique styles of spark plugs are produced for 3.0L engines. Each style is identified by the part number letters.1. AWSF-32P indicates the center electrode is enhanced with platinum and are used in cylinders 4, 5 and 6 of the engine.
2. AWSF-32PG indicates the ground (side) electrode is enhanced with platinum and are used in cylinders 1, 2 and 3 of the engine.
3. AWSF-32PP indicates platinum enhancement on both the ground (side) and center electrode. These PP spark plugs are the service replacement for all cylinders of the engine.
If a spark plug is removed for examination, it must be reinstalled in the same cylinder. If a spark plug needs to be replaced, use only spark plugs with the service part number as shown on the engine decal.
Clean spark plugs as necessary with a professional spark plug cleaner (follow manufacturers instructions). Inspect the firing tip. Replace with the proper replacement spark plug as listed on the VECI label, if the spark plug is worn or damaged.
