SOURCE: spark plug gap

Notice: This engine has aluminum cylinder heads. Do not remove the spark plugs from a hot engine, allow it to cool first. Removing the spark plugs from a hot engine may cause spark plug thread damage or cylinder head damage.
Gap the spark plug, using round wire type spark plug gap gage. 


Gap Adjust the spark plug gap to 1.14 mm (0.045 in).

DO NOT coat the spark plugs with anti seize compound. Over torquing could occur and damage to the cylinder head threads may result.

If your going to use Platnum plugs, DO NOT GAP them. Just check the gap and if there not the right gap, ask for new one's with the right gap.

The metal on the PLatnum plugs, are harder and my break apart in the cylinder .

Good luck and hope this helps

How to change spark plugs in 2005 chevy silverado ?


half of the plugs will be on the left, and half on the right of the engine. You will find a cable going in between the exhaust heads, those cables go to the plugs.

Use a plug puller to reomve the caps with out damaging them,

then remove the spark plugs with a socket designed for spark plugs, then verify the proper gap on the new spark plugs

install the new plugs,

place the caps back in the same spot they came from

the caps should make a clicking noise if they seat right.

2000 Chevy Silverado 1500 with 5.8 liter gas motor reading code saying spark plug gap is incorrect on #3 and # 5 plugs but gap is correct


you may have a bad coils or coil boots in those cylinders, try switching the coils to a good cylinder and see if the codes change to the other cylinders, if they change then replace the coils, the computer see it drawing more cuurent so it thinks its the plug because its not misfiring or completly grounding out.
