How to replace the spark plugs in your Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?

To change the spark plugs in your vehicle, you will need some important tools like a ratchet, socket for spark plug, various extensions and gap gauge appropriate for gap adjustment. Though a specific plug wire removal tool is available, it is not required. Ensure you have a torque wrench to fit the new spark plugs tightly. The first step involves allowing the engine to cool off completely and then checking the new plugs for any defect as well as making sure that their gaps are adjusted using a gap gauge if necessary. The gap must match with the specification on Emissions Control Information Label. Remove one spark plug wire at a time by only holding and pulling on its rubber boot or by using the plug wire removal tool if needed. If there is compressed air available, blow out any debris around the spark plug hole to avoid contamination. A spark plug socket has to be used to remove the old spark plug turning it counterclockwise. Reviewing the old spark plugs helps determine an engine's state of affairs. Thinly coat threads of new plugs with anti-seize compound before installing them. Using your hands screw in a new one until it becomes impossible to turn any further then tighten using a torque wrench or ratchet. In situations where reaching plugs poses difficulty use short lengths of rubber tubing as threading tools. Lastly, connect each wire from the plug wires by twisting and then turn until it is locked into place and repeat this process moving on to another one at a time so that none of these wires get mixed up.
