How to Change Your Spark Plugs Part 1 - Jeep 4.7L

The first video in a two part series: A quick tutorial on how to change your spark plugs in a 2005-2007 Jeep 4.7L V8. The principles apply to most gas engines, just access and location might be different. Another few precautions when changing plugs on aluminum heads: "When changing spark plugs, wait until the engine has cooled to remove the plugs. This is very important with aluminum cylinder heads because it reduces the risk of damaging the threads in the cylinder heads when the plugs come out (aluminum is a much softer metal than cast iron)." "Most threads on spark plugs for engines with aluminum heads are either precoated to reduce the risk of thread damage, or the plug shell is made of a nickel alloy. If the plug shell is black or plain steel, however, you should put some antiseize to the threads, and reduce the applied torque by about 30 to 40%." "Do not use antiseize if the plug shell is nickel or has been precoated. Antiseize acts like a lubricant and may allow too much torque to be applied to the plugs, damaging the treads in the cylinder head." http://www.aa1car.com/library/sprkplg...
