GMC 19302741 Spark Plug Asm

To avoid misplacing the wires, after opening the hood, start by labeling each spark plug wire to ensure you place them correctly during the reinstallation of new spark plugs. Several tools are needed to do this job such as a spark plug socket with a padded interior to prevent porcelain insulators of new plugs from being damaged, pipe extensions of various dimensions, gap gauge for checking and adjusting plug gaps and a torque wrench used in tightening the new plugs. It is advisable to purchase new spark plugs ahead of time with set gaps that can be adjusted to meet specifications as well as replacing them one at a time. You should give your engine enough time to cool before removing any plugs, during this period scrutinize the new plugs for faults and adjust their gaps if needed. Checking the gap will entail using a wire-type gauge to make sure that there is a slight drag when sliding it between electrodes so that it matches up with the emissions control information label specified gap. This adjustment is done by bending slightly side electrode without breaking off or damaging porcelain insulation. When engine is cold remove one spark plug wire from one plug using preferably plug wire removal tool blow clean any dirt or debris around the spark plug hole through compressed air or bicycle pump so as not to contaminate it. Use a Spark plug socket with a short handle in order to unscrew the plug counter clockwise. Examine removed plug for signs of how the engine has been running since it was last replaced. Insert one of the new plugs into the hole screw it in finger tight then finally use torque wrench or ratchet on it. Rubber hose should be used threaded for threading instead cross-threading taking place.Threaded rubber hose can be used to thread into, preventing cross threading.Before connecting wire from a hot ignition coil onto another spark-plug check out whether there are any defects in those wires and finally repeat such operation regarding remaining spark-plugs; replace each one individually so as not mix up the wires.

The engine's side contains the spark plugs. In order to replace them, you will need a socket for spark plugs, various extensions, gauge for the gap, tool removing wires of the plug and torque wrench. Instead it is more advisable to purchase the new plugs earlier, align them to their desirable gap and change them one at a time. The right type of plug must be obtained that suits to your engine; this information is indicated in the Emission Control Information label found under engine hood. You should give room for cooling off before attempting to remove any plug(s). Meanwhile inspecting new plugs for malfunction and readjust gaps is proper. For removal of spark plug wire from one particular place just pull on the boot while noting that other parts should not be touched by hand. Spark plug holes are dirt-free with air compressors available or using bicycle pumps as alternatives. A socket extension will be necessary since reachability of spark plugs is difficult most times. By turning it anticlockwise will remove plug. Comparing an old one with chart can provide some understanding about engine's condition during operation period. Put anti-seize compound lightly on threads of brand new one and then screw it tightly into that hole with fingers only or use suitable spanner if needed. With a ratchet or torque wrench make it snugly tight after all has been done properly before you attach this second latest piece yank out first and turn around so they are seated properly Attach wire by twisting it until it sits straight down onto top part of each cylinder head Make sure not to mix up wires during replacement process where you'll take out individual ones.

It is advisable to allow the engine to cool completely, check the new plugs for defects, and adjust the gaps.
