Lincoln Navigator Maintenance and Repair

  • I have a '00 Lincoln Navigator. Apart from the Air Suspension failing a couple of times, I have not entirely been unhappy with my decision to purchase this car. However, after taking my car to the dealer recently to have the Air Suspension looked at again, that may have all completely changed and I am hoping to get some guidance from someone on this board.
    2 days ago, I brought the car in to have the suspension looked at as the CK SUSP light came on and the compressor stopped running. The service manager had looked at it about a week earlier and said that the previous failure was due to a bad relay and replaced. While there, I asked that the technicians take a look at the Service Engine Soon light which came on recently as well.

    When I picked the car up, the service manager advised that the susp failure was due to a loose ground in the car. This was located and fixed and not only is the susp working again but also the auto door locks and MPG indicator (YAY!!).

    BUT, and this is a very big BUT, the service manager said they also took a look at what was causing the Service Engine Soon light to come on. When they pulled the "codes" from the car, they found that that the "left bank" was running lean. Additionally, a hose in the engine compartment was also leaking air and could be heard outside the car. They found that they car was approximately 3 quarts low on oil and compression in the #6 cylinder was low. Needless to say, they repaired the hose, filled 'er up with oil, and checked the "left bank" and the engine service light was reset. In the process, they detected a faint noise coming from the motor (bear in mind that I am not sure in what order these problems were detected). They took a closer look and concluded that the problem is "deep within the engine" and cannot be easily repaired. IT will likely require a new engine.

    At the risk of sounding defensive, the car was serviced by the dealer 2 months ago and, at that time, the oil/oil filter, air filter, coolant, and transmission fluid was changed. The car does not leak or burn oil and assuming that they added the correct amount of oil 2 months ago, how could 3 quarts just disappear? Additionally, if the car was low on oil, would I not be able to tell from looking at the dashboard indicator? OR, would there be a noticeable loss in performance or excessive engine noise or something??

    Let's say that my only option is to replace the motor, would the car not have to be there more than 2 days for them to determine that? AND, would they not charge me for the time they spent to investigate the problem? They also did not charge me for repairing the loose ground which resulted in my suspension failure.

    As if this was not confusing enough, the service manager recommended that I trade the car in. NOT for a new Navigator but for another car and preferably not associated with their dealership.

    My next step is to bring the car in to another dealership to get a second opinion. If someone out there is/has experienced this same problem, please advise. If not, I would equally be interested in hearing your thoughts on this situation and any advise you may have for me.

    Thanks in advance.

    You may have already done something, so ignore me if I'm way too late.

    I have found that a lot of service techs don't know that your Navigator takes more than the customary 5 quarts of oil, and so they don't fill it up when they service it, and you start out 2 quarts low when you leave. That may explain why it needed 3 quarts.

    Why they didn't charge you could be alterior, but also they just could be sympathetic.

    I'm wondering how long you have had the car. Did you by new? If not, now long ago?

    Very odd they suggested you trade the truck in "elsewhere". That I totally don't get. But I agree, a second opinion is warranted. If indeed, something is detected that is serious, I also would trade it off unless it is still under warranty, which I'm doubting it is.

    I had a 99 Navigator that gave me -0- trouble for 4.5 years. I have an 03 that I'm now equally happy with. I have never heard of anybody else with this bizarre story. Wishing you the best.

    I just bought a used 01 Navigator and do not have the door lock code. According to the owner's manual the code is on the computer module but I can't seem to locate it under the hood. If anyone knows where it is I would greatly appreciate the help.
  • What type of engine coolant/antifreeze is recomended for my lincoln navigator?

    I don't know where the computer module is, but you can set your own unlock code numbers. There is a section in the owners manual telling you how.
  • I also want to know where the spark plugs are located 00 Navigator?
  • This morning my 99' Navigator 4 wheel drive had a problem with the air suspension. The back of the truck looked like a low rider truck and it had a very bumpy ride. By ging on the internet I figured out it was the air suspension. I could her the compressor working but the back would not inflate. I checked under the hood noticed there was a loose black hose(I don't know what it's called) with some kind of metal valve, it is next to the fuse box. Found out where it should go and conected it, but it was still leaking air. I decided to hold it while turning on the ignition and the back started to go up, so I guess that's the problem?right?Where can I get this hose/air line and what is the correct part name?Is it expensive? Should I still have someone check it out? Also do you know where I can get a diagram of all the engine parts (big ad small) so I can have for the future?

    The spark plugs on the 98 navigator are located under the fuel injector rail. The coil wire has a bolt that has to be unscrewed. The front 4 plugs are a little difficult to remove and the rear 4 plugs and coils are much more difficult, I was lucky to know a mechanic who works for a lincoln dealership and he talked me out of trying this difficult task. The reason is that the frame is from a van!!!!!

    I just bought a 2004 navigator with nav radio with Sirius and rear dvd system. After spending $5000 dollars for this system, I discovered a huge design flaw. You can't listen to sat radio while the kids in the back are watching a dvd with headphones. There is only one aux input on this radio which is shared by the two systems. "Dual play" is not feasible. Utter stupidity on the part of ford and Visteon engineers. My dealer claims ignorance and ford has no solutions and was quite apathetic. This is not a problem with the GM equivalent products.

    And, if you don't have the owner's manual, the door default code, should be on a white sticker, under the dash somewhere, driver's side. If you can't see it by lying on your back and looking up with a small light, your dealer can give it to you from the VIN number. Then, I'd suggest you use that default code to change it to another code. That way, if someone discovers your code, you can change it again. If they discover your default code, you're screwed, as it can't be changed. Good luck.

    Is almost always the result of a bad tire on these new Navigators. I have it too, but if I put the front tires on the back of the truck, it goes away. So, your dealer isn't shining you on, it is a common complaint, as the rack & pinion steering transmits road feedback very effectively to the steering wheel - but also any little defect in a tire or brake will also be felt. Try rotating your tires front to back.
  • My navigator was 3 weeks past the 4 yr warr, but had only 26,000 miles . Both dealer and Lincoln said 'sorry'. The cost to me was $491 plus $54 towing. I thought that some compensation should have been offered beside 'sorry'. Ken Leander

    Sure would have been nice if they had. But rarely do any manufacturers extend coverage on a discretionary basis.
  • I purchased my aviator in April of 2003. I have had recurring intermittent slipping/engagement problems with it since September of 2003. After being in for service 6 times with the same problem I am going to the dispute settlement board on Thursday.
    I have been without my Aviator for a total of 59 days for the specific problem listed. 33 total days of service since I first purchased the vehicle in April of 2003 to April of 2004.
    The listed problem is intermittent when the trans gets hot. Primarily in stop and go traffic conditions. It will engage in drive and then begin to slip until it just jumps into gear. This continues at every stop unless I stop the vehicle and put it into drive. It will still continue even afterwards on occasion.
    The problem has been addressed during the service visits with parts including the solenoid body, pump bolts, pan gasket, stand pipe and o-rings. Still a recurring problem.

    Has anyone had a similar experience with their Aviator and/or attended the Dispute Settlement Board trying to find resolution to their problem and what was the outcome.

    Transmission problems with New 2004 Navigator with 1000 miles on it (3rd week), similar slipping, complete disengagement problems, just happened and in the shop now. I am very interested in the problems they tried to ID. I told them to come pick up THEIR car, I am trying to exchange now because I am afraid of your very situation, ongoing unidentified problems. I will pass along their diagnoses.

    Does anyone else have this problem??

    This is the most common complaint on the Navigator and Expeditions since the 03 version came out with the very sensitive Rack & Pinion steering box came out. It's the tires. ANY imperfection in the tires, be it out of roundness or imbalance is transmitted up to the driver as well as any road imperfection as well. There is a special balancer that some dealers have, some don't, (It's a Hunter, something or other, check back in this site, and the other Navigator site and Expedition Problems board, and you'll see this problem more than anything else and find it) that is most effective at resolving it if it's balancing. If you have an out of round tire, switching the tires from front to back will tell you that. Then you can demand a new set of tires. That's what I had. And they were Michelins, which are the best, and one of them wasn't round. New tires fixed it.

    It is located on the anti-theft computer inside the vehicle.It is under the dash on the firewall beside the top of the brake pedal.It is 5"x4"x1-1/2" thick and white in color.There should be a 5 digit number on the label.
  • this vehicle is at the dealer already 2nd week in a row.
    they re balanced & rotate the tiers,they checked the rotors,they checked the driveshaft,they took the rear end axle down,in other words they took apart the truck & they can not figure what cause the vibration,they run the truck on the lift they dont get any vibration, ones they drive on the road the vibration is there,they took a set of tiers from a stock vehicle balance them & test drive they still have vibration,
    i have a heart condition I'm on medication daily, i dont get anywhere with this dealer or ford lincoln co.
    please help before i get my heart attack.
  • nvbankernvbanker Posts: 7,285
    Sounds like the dealer is doing everything possible to help you - what else can they do? What else could Ford do besides buy back the truck? Be patient and nice, and they just may do that for you.

    Has anyone tried getting the tires balanced using one of the Hunter 9700 machines like mentioned in msg#4331 on the tires, tires, tires message board. I had a similar issue with my Lexus and it was resolved by one of these machines at the dealer. The tire retailer used an older type of balance machine but the dealer had better equipment.
  • Have new 2004 Navigator purchased 9/13/04 with 1500 miles. Experienced two random occasions where car would not start after turning ignition key. Car spontaneously started after 5 and 10 minutes respectively. Took car in to the dealer and explained the problem. After they did the cursor diagnosis I was told that they did not know what the problem was and would have to go through the entire vehicle systems like "looking for a needle in a hay stack and could take some time to do". Has anyone had a similar problem and if so what was the problem?
  • nvbankernvbanker Posts: 7,285
    Oh man....that's the hardest problem of all to find, since you can't find it unless you catch it in the act. So here's what I recommend;

    1) Ask your dealer to swap out the battery with a new one. Sometimes, those batterys can go up and down like that, unless the problem isn't that it won't crank. It was hard to tell from your description.

    2) If the car did crank, forget #1. If you did #1, and it does it again anyway, then for #2, give the car to the service manager, get a loaner from him, and tell him to use your car as his own until it does it to him, and then find it, and fix it, no matter how long it takes. It's a pain in the [non-permissible content removed], but it's you're only chance to find it. Otherwise, you never know when it's going to let you down, and unless Jesus works at your dealership, it's their only chance to find it too.
    Good luck.

    Engine light is on, I hook it up on a code reader and it comes up with lean left bank and lean right bank, I replaced the air filter, spark plugs check the PCV valves and all visible vacuum hoses, did not find any leak, turn engine light off, take it back on the road, when accelerating at speed between 30-50 it seems to buck or no power, engine light was flashing, then after it drive with rpm at 3000, engine light go steady on and it start to work normal,, what else can cause this---help
  • Your dealer SHOULD claim ignorance, because this is common sense, THINK....the solution to your problem is not that hard to figure out...go to Radioshack.
