Remove the spark plug wires from your 2004 Chevy Malibu spark plugs. Remove the old spark plugs with a 5/8 deep well socket, by turning the socket to the left. Reverse the process to install the new spark plugs.
To change the spark plugs on a 2000 Malibu, you need to get a spark plug socket with a u-joint in order to access the plugs on the firewall side of the engine. The plugs up front are easy to get at, and don't require anything special. Word of warning, if your Malibu has relitivley high mileage on it (80,000+) and it still has the factory plug wires, there is a good chance that they will break on you when you have to pry them off of the plugs, go ahead and replace the plug wires when you replace the plugs.
If you do not have any problems with plugs, change them when you replace the timing belt (do not forget to replace the spark plug wires too).
6000 miles

How to replace spark plugs in a 1989 jeep cherokee?
Depends on the type of spark plugs. Factory plugs around 70 - 100k depending on the condition of the plugs. I would replace the spark plugs out with some AC Delco iridium plugs they will last you 100k+.
