There is no recall on the cylinder heads of a Navigator,if it was then the repair would be free,so he must be refering to a technical service bulletin.
The problem with having head redone is if they resurface the head then the bolt holes in the front timing chain cover will not line up with the bolt holes in the head when you reinstall the cover. Ford has recently come out with oversized headgaskets for this purpose so it is do-able now but it would have to be done by a machine shop fimilar with this proceedure.We tried to have this done one time by a local machine shop here and it was a total disaster.Wound up replacing heads anyway. The problem with this type of repair though is that the dealer wouldn't be able to warranty the repair but if it saves you a couple thousand that probably wouldn't matter to you. But you would definately need to be aware of this.

Where is the coil pack for cylinder 5 located at for a 2002 lincoln ls

Hi, welcome to my name is Shawn and I will be answering your question.

They have an individual coil for every plug on this engine. Do you have a check engine light on if so if you retrieve the code it should be a P030X misfire code the X being a number between 1 and 8 identifying the cylinder that is misfiring. #1 being the passenger side front - #4 passenger rear #5 driver front #8 driver rear. They go in order 1-4 passenger side 5-8 driver side. If this is a 6 cylinder then coil 1 would be the passenger side front coil 3 would be the passenger side rear. Coil 4 would be the Driver side front and 6 would be the driver side rear. The coils are located under the center cover on the valve coves.

I hope my assistance helped you and resolved your concern, if you need further assistance please ask.

2004 lincoln nav...shaking..trying to cut off...mech said 3 plugs and wires need oto be changed...can I do this or should I do A complete tune up?

There haven't been Tune-Ups,in the last 30 years,on vehicles that are all electronic
You have COP, Coil-On-Plug Ignition System,no plug wires
Spark plugs and Air Filter and other electronic cleaning, is called preventative maintainance,and as I said, that way for decades.

If you have Codes PO-301 thru PO-308,you may have a bad coil or two. I doubt you have three bad.
Their $59.00 at the auto parts store. Install them yourself

The only tuning that is done,is by the PCM (computer),not a repair shop mechanic

Also,scan the Throttle Position Sensor,they fail. You can get that at the store also,and don't need a dealer to sell you the entire throttle body for $700.00.

Clean the MAF Sensor ,with CRC MAF Cleaner

Expect the EGR Valve to fail.

Change your trans fluid, flush your power steering fluid and brake fluid every couple years.

Have the vehicle scanner for codes anyway. The fault may not be a hard one. Then depending on what is found do the repair. If no codes are found have a technican do a cylinder leakage and injector lbalance test. This will tellus if the cylinder is leaking vacuum and whether the injectors are firing.

I put diag tester on 2001 linc nav it said lean 1

If you getting a lean code you may want to start by changing the fuel filter. I'm not that familiar with the Navigator but, If you look at the coil pack they have them numbered. The right front (passenger side) cylinder is number "1" it's 1 2 3 down right side and 4 5 6 on the drivers side, that's for a V-6. A V-8 is the same except 1 2 3 4 and 5 6 7 8.

Misfirecyl#5 onlincoln ls 2002

these are individual coils per cylinder replace your number 5 coil that is most likely the issue also it may be time for your spark plugs also.if this is a 8 cylinder the #5 coil will be drivers side front first coil.I would get a good coil from the dealer.
