To change the sparks on a 2005 4.7L Dodge Dakota you will need the following:
- Spark plug socket
- Torque wrench
- Flat-tip screwdriver
- Make sure the truck is cold!!!
Note you will have to remove the air intake located at the top of the engine, and will have to move some of the coolant lines out of the way.
At the top of the engine there are 4 sparks on each side. The coils are held in place with a 10mm bolt. Undo the 10mm bolt and unclip the coil. Next pull out the coil.
Insert the socket, with extension into the spark plug hole.
Remove spark plug.
Check the gap on new spark plug, it should match stock.
tighten to approximately 25ft.lbs. (check spark-plug packaging for exact torque requirements).
repeat this process with all other sparks.
be sure that no dirt gets into the spark plug holes.
