How to change spark plugs in 3 liter v6?
Replace one spark plug at a time. DO NOT DIS-CONNECT MORE THAN ONE SPARK PLUG WIRE AT A TIME AS YOU COULD LOOSE THEIR ORIGINAL CYLINDER MATCH AND THE TRUCK WILL NOT RUN.
So, one wire and one plug at a time. The spark plugs should be gapped to .031 inches and torqued to 13 Ft-Lbs.
