How do you change spark plugs on a 2003 Dodge Durango?

I can say that this is a job that most anyone can do, but it takes some consideration and a little bit of time. Now first off you need the CORRECT spark plugs and you need to know the spark plug gap. You also need to know what engine you have, so that you will know what plugs to get. Here is the two engines that come with the 2003 Dodge Durango. One of them is yours. I assumed you had the 4WD???

5.7L V-8 Spark Plug Removal



Eight of the 16 spark plugs are located under an ignition coil; the other 8 are not. If spark plug being removed is

under coil, coil must be removed to gain access to spark plug. Refer to Ignition Coil Removal/Installation and

observe all CAUTIONS and WARNINGS.

Before removing or disconnecting any spark plug cables, note their original position. Remove cables one-at-a-time.

To prevent ignition crossfire, spark plug cables MUST be placed in cable tray (routing loom) into their original position.

Refer to Spark Plug Cable Removal for a graphic.

Before installing spark plug cables to either the spark plugs or coils, apply dielectric grease to inside of boots.

1. Remove necessary air filter tubing at throttle body.

2. Prior to removing ignition coil (if coil removal is necessary), spray compressed air around coil base at cylinder

head cover.

3. Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign

material from entering combustion chamber.

4. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert.

5. Inspect spark plug condition.
