2003 Grand Cherokee 4.7 auto- not H.O.

I have the factory service manual and I can not FIND the plugs on this vehicle - and I once upon a time was a Jeep fleet mechanic (258 DJ's).
Can somebody throw an old man a bone and tell me how to change the plugs on this vehicle?

Thank You,
Putnam

The plugs are in the coil packs.

Actually, each individual spark plug is located under each ignition coil. Please read carefully;

Firstly, if it is the 4.7L HO (high output), do not sub. any other part number for the original plalinum tipped spark plugs as serious engine damage could result! If the 4.7L V-8, pre-ignition will result.

Prior to removing the plugs, spray compressed air around the base of ignition coil at cylinder head. This will ensure that nothing foreign gets into the combustion chamber.

You may also have to replace coil 'o' rings. Inspect them when apart.

I can't cut and paste, there is a lot of info I could tell you. I could always fax you if you like...
