How To Replace Spark Plugs 2000-06 Chevy Tahoe

All right, we wanna disconnect the battery, disconnect the negative cable. Use an 8-millimeter ratchet wrench or a wrench. And then slide that out of the way. We can take the spark plug wire off just on the spark plugs side. You might have to use some special pliers, like hose pliers, to get there boots off. Just like that. And just slide that to the side.

Now before you take the spark plug out, there could be some dirt and debris around the plug. Just take some compressed air and just spray right around the plug itself. And take a spark plug socket. This happens to be a 5/8 spark plug socket. And loosen the plug.

And slide the plug out. Take the new spark plug, put it in your spark plug socket and just carefully line it up. And you wanna torque this to 11 foot-pounds. And reconnect the spark plug wire, just line it up with the plug. Lock it down and then you can do the same procedure for the other ones.

Now we can hook up the battery. Line it up, get it started. And snug it up. Just make sure it's not loose. That's good.
