Lincoln Navigator

i had the same problem there is no getting around it you have to get it towed to the dealer ship yes they suck :( and they have to reset the comp. this happened to me when i had a street mechanic fix my heater core. even if everything is set up right, and your missing a few vital screws it will cause the theft light to come on because its missing pieces( screws)

There is a small air tube located on top of the engine. Check it, it might have a leak.

unplug the unbolt, and replace them with ford expedition coil overs the same year.

THere are 8 coils and plugs. THey are located on top of the engine, in rows of 4 (one row on each side), in the middle of each valve cover, under a metal plate. Remove the plate on each valve cover, and you will see the coils each with an electrical connector and held down with a 7mm screw. Remove the coils and down in each hole (about 3 inches down) is the plug, one under each coil. They require a 5/8 spark plug socket to remove.

Disconnect battery negative cable. Each plug has it's own coil. Remove each coil by the one screw attached, disconnect electrical plug and pull out the coil boot. There are two pieces to each coil.

I'm not a mechanic / technician but I know the engine cylinder locations are numbered :

firewall

4 - 8

3 - 7

2 - 6

1 - 5

so I assume the coils would be :

D - H

C - G

Remove the seat. Remove the strap that is across the airbox and battery by reaching down behind the battery and sliding the strap clip to the left side of the bike while relieving the tension on the strap. Pull the airbox lid off. Remove the white plastic filter holder then remove the foam filter. Clean the filter in detergent and water, let dry. Saturate the filter with motor oil, squeezing out as much excess as you can. Put the filter back in, squeezing it as far forward in the box as you can. Install the white plastic filter holder as far forward as you can, it should snap into place. Reinstall the airbox top, be sure to note the airflow direction (there should be an arrow on the airbox top) Stretch the rubber strap over the airbox lid and battery and slide the clip behind the battery with your hand, to the left side of the bike. When you can feel the clip is past the notch for it, slide it to the right of the bike and it should hold.

Fuel Filter Location The fuel filter is located along the frame rail under the vehicle and is accessible only from underneath the vehicle. Fuel Filter Removal & Installation 1. Disconnect the negative battery cable. 2. Properly relieve the fuel system pressure. 3. Raise and safely support the vehicle securely on jack stands. 4. Remove the fitting safely clips by gently prying them off. Usually they are held to the fuel lines by small retaining straps, however take care not to lose them. 5. Insert fuel line disconnect toll T90T-9550-S into the quick-connect fittings on the fuel lines. 6. Push the tool into the spring lock coupling and release the garter spring and separate the fitting. Twisting the line sometimes aid in releasing stubborn connections. *** Caution *** Fuel will most likely run out of the line after it is removed from the filter. 7. Repeat the procedure for the other fuel line. 8. Grasp the fuel filter and carefully pull it straight out of the retaining clamp. To Install; 9. Push the filter into the retaining clamp aligning the front lip on the filter into the groove. 10. Attach the fuel lines to the filter until an audible click is heard from the connection. Sometimes the click is very quiet, so test the fitting by gently pulling on the line to see if it comes loose. 11. Attach the fitting safety clips by snapping hem into place over the fittings. 12. Lower the vehicle. 13. Connect the negative battery cable. 14. Start the vehicle and check the filter and lines for leaks.

The 2004 Lincoln Navigator has a 9 ft. 10.8 in. (118.8 in.) wheel base.

The air filter housing is located to the right of the engine and to the left of the fuse/relay panel. Simply undo the clips located on the housing and remove the old air filter and replace it with the new one. It is recommended that the air filter be replaced every 30, 000 miles or 24 months, whichever comes first.

According to the 1998 Lincoln Navigator Owner Guide :

( Motorcraft MERCON automatic transmission fluid )

* the type of fluid used should be engraved in the automatic transmission fluid dipstick or indicated on the dipstick handle *

I had trouble finding the keycode for our 2006 Lincoln Navigator. You have to remove the fuse panel located underneath the glove box, which is to the right. I had to crawl under the glove box with a flashlight and look around inside the fuse area. I saw a tag that had 5 digits on it, so I tried it out, and it worked. It was located way up inside the fuse area, so I had to look hard. I wrote it inside the owner's manual for easy access later. Hope this is helpful for anyone else with the same problem.

Because there is something in the car that keeps using electricity even when the ignition is off. A dash clock, an alarm, maybe a boot/hood/ glove comparment lamp stuck in the on position.

I would check the oil pressure sensor to see if it might have gotten disconnected some how. Might want to check the viscosity rating of the oil that was used. Some cars are really picky about the weight of oil. take it back to the dealership if they were the ones who did it last. Let them know of the problem asap and make sure you let them know that they were the last ones to touch the car.

The 2009 Lincoln Navigator has 39.5 in. of front head room.

Or remove lower radiator hose

The 2005 Lincoln Navigator has a 6-speed automatic.

Well maybe yes and maybe no but you can retro fit it for one if yours does not. The air box is located on the passenger side below the glove box. You will first need to remove the black plastic cover, then if their is already a filter in place remove it by pulling down on the tab (black or white). Then simply put your new filter in place F65Z-19N619-AB is the motor craft part number for all Navigators 1998-2002. If there is no filter like in the older Nav's you must cut (very carefully) the black plastic rectangle area out in order to install the filter. Not sure why Ford did this but it is a pain use a sharp knife or a roto drill to cut out around the plastic insert it will simply fall out and allow you to install the filter. Be sure to file down the sides if they are sharp to ensure no damage is done to the filter/ensure proper fit. Hope this helps
