Where are the Spark Plugs located on my Lincoln LS 2001 3.9L? How do I remove and replace the Spark Plugs?

Hi Danny,I have a 2004 Lincoln LS, 3.0 haven't had that problem so far,have 125.000 miles on it.Here's a video I found on your sensor,a lot of things are put on our engines that are hard to get to,like the spark plugs. Lincoln ls 2001 V6 3 0 temperature sensors YouTube

The spark plugs in the v6 can become an involved job as the upper intake manifold. The LS uses a Coil on Plug (COP) ignition system, meaning that the spark plugs are located under the ignition coil

Generally in a spark plug is 60000 kilometers, if fuel is bad need in early, remove the spark plug, such as for auburn or rust color, spark plug showed normal; Such as stained with oil, shows that the spark plug gap imbalance or too much oil, high tension line short circuit or open circuit; Such as black smoke, spark plug type cold wrong or mixture is thick, the oil is up; Such as the top between the electrode and sediment, when for the oily sediment, shows that the cylinder into the oil has nothing to do with the spark plug, when the black sediment, spark plug carbon deposition and bypass, when grey sediments, is a gasoline additive covered electrode lead to lack of fire; If serious erosion, such as the scar at the top, with black pattern, electrode melt, showed that the spark plug is damaged.
hope help you -auto diagnostic tool

they are located under the manifold you have coil packs on them to remove.you have to remove the manifol to get to thje ones on the pasengers side.

This is for the 3.0L engine:

3.0L Engine

1. Remove the engine appearance cover.
   
2. To access the right bank ignition coils, remove the upper intake manifold..
   
3. Disconnect the electrical connector from the ignition coils.
   
4. Remove the bolts.
   
5. Remove the ignition coils.
   

To install:

1. Replace the ignition coils.
   
2. Connect the electrical connector to the ignition coils.
   
3. Remove the upper intake manifold for the right bank ignition coils.
   
4. Replace the engine appearance cover.
   

there is a flat plate on top of the valve covers you need to remove then remove each coil the plugs are under the coils

easier said than done.
driver side is staight forward.
remove coil packs from blugs, then remove plugs.
passenger side needs intake removed to gain access to plugs

it is down under the intake manifold. the intake manifold must be removed to get to it. this vehicle is known for developing a vacum leak in the elbow hose that connects to pcv valve, so ive done a few.

are you handy with tools???
get youself a hayes manual. start there.
if not better let teh pro. do the job.

put it in your ***
