Question about 2004 Lincoln Navigator

2000 Lincoln navigator air suspension

I just purchased my navigator and it seems the pump is really loud.. and it runs alot.. whenever entering the vehicle. It was fine for about 3 weeks then I notced the air suspension light was on and it was very bumpy. I took it to the shop where they cleaned out the relay plug-in they said it was loose and corrodid .This seemed to take care of the problem for about 2 weeks. Then it did the same thing . The day i was going to take it back to the shop it started working again... I noticed that it seems to work on days when it's not so cold outside?? If that even makes any sense...
Where should I start?

    I took it to the shop today . The guy there said maybe it has moisture in the system and when it gets really cold out it is freezing up ? Ever heard of this ?

The air chambers are worn out and this has caused a heavy load on the compressor, causing IT to become loud. The relay could be oxidized from excessive runtime...accordianman

Tps on nissan quest makes loud noise when accelerates


As I look at your letter, which is very good, I might add, here are the few things that occurred to me.
The "loud squealing" should be a belt.
You have one or several belts, and if they get loose, or are worn out ( that includes the belt rubber getting old and hard) they will squeal like that.
However, the squealing also may be coming from one of the pulleys the drive belt or belts are attempting to turn.
If you have a bad bearing in one of the pulleys, you can get that loud sound like " a train".
If you are really careful, a "mechanic's stethoscope" might help you.
That is to take a really long screwdriver, and put the tip on each of the pumps or base of each pulley, and the handle end to your ear, and you can hear the bad bearing "scream" with the engine running.
Be blessed.

Put new battery in car. Now it is hard to start. Replaced fuel filter no help. What could the problem be? Engine cranks ok. Seems like fuel not getting to engine. Seems to run fine after it is started....


fuel pump is in the tank but don't think that it is the problem if it runs fine after started. sounds like a cold start problem alot of these vehicle have what they call a cold start injector that supplies the initial fuel to get the car started and then the regular injectors do the rest have this checked and make sure it is working properly.

Car cranks, but hesitates to start after sitting for over 24hrs


Tune ups are always a good place to start , including air, fuel, plugs and for the extra 5 bucks a PCV valve. If these havn't been done in the last year at least might want to start there. If that doesnt make any difference please post again and we will look at something else!

Loud air intake engine noise on startup


I would guess it is the electronic fan clutch. It will cause the fan to run too fast (very loud) and the light will come on sometimes.

Loud air intake engine noise on startup


If the vehicle has a clutch fan, verses an electric fan, sometimes the clutch will spin the fan too fast or at erratic speeds. I'm not saying that's what it is, but just one possible reason. Seeing how you have the warrany, I would take it in and not leave until they have remedied the problem. Let us know how everything turns out and good luck.
