As these are outstanding engines !! Treat them well and they will give back !! I have an 89 Mark and right now it has 301,000 miles !! Change the oil and(good) filter every 2500 miles and give it PREMIUM Fuel !! Make sure the cooling system is always in good condition, and drive belt. Also really good spark plugs and wires !!

i was told the alternator was going bad and somehow it was backing up into the speedometer

From 1984 to 1989 they did not have any airbags but 1990 - 1992 they had only one in the steering wheel...

There is a small hole below the compass button that allows for something small such as a paper clip... press and hold it and it will allow for you to configure the compass..

I converted my 1990 LSC with a kit from strutmasters and notice very little diffference overall, and have noticed bodyroll is less in the slalom with the springs.

That's kinda tough to answer without knowing more information like Miles, year, options,

Special Edition's are worth more especially 1990 grey special Edition's because they are rare.

Generally the lower the miles the more it can be worth because it would be less worn and usually in better condition. Hope this helps

On the front on both sides you see this thing that looks like a little spring covered with matirial it takes a star screwdriver and you can adjust it up or down, it's hard to explain what it looks like but it's right by the air bag

there is a coil spring conversion made by Arnott, i have it on my 91 LSC SE and the ride is so much better, i would check out Eibach, Tein, and other spring companies, as well as cross reference parts from a thunderbird/cougar/mustang of the same year range There are ride height adjusters under the front and rear of the car to lower the car all you need to do is adjust these and you can drop it at least a couple inches. only make sure car is supported by jack stands when doing so.

There are a few things that could be wrong. 1- It could be the computer located in the trunk behind where the switch is for shutting the air ride off. 2- A leak in one of the lines or the bags. 3- The compressor is bad. 4- A bad air bag solenoid. 5- A bad height sensor.

The Air Ride system can be scanned for trouble codes too that can help you better diagnose the system. Also there is a Club you can join and get a lot of help from them too, go to: " thelincolnmarkviiclub.org "

If the car has been sitting for awhile maybe the heater fan has a mouse nest in it. Not much info to go by . Does it get louder when fan gets turned to hi ? Could it be a hissing sound from one of the vacuum hoses being off ? Does it change at all when climate control unit is turned off? Message me and I can try to help you further.

good points, but there is no vacuum on the climate controls, just electronic servos. If you do hear a vacuum leak, the only source i know would be the parking brake line.

1-3-7-2-6-5-4-8 is the firing order for the 5.0 H.O. engines... If it's not the H.O. engine it is: 1 - 5 - 4 - 2 - 6 - 3 - 7 - 8...

LH side or RH side take the plastic shield or inner fender(mud gard) that is below the fender then take the signal lamp off ,after that start taking the nuts that holds the bumper cover and fender close to the tire it could be an 8 or 10 ml socket ,open the door and you'll see 2 more fender bolts take those off also ,under the car where the fender ends it has two more bolts take theme off then on the upper seccion of the fender it has more screws. good luck!

First you take out the driveshaft, then take out the starter "make sure to unhook the negitve battery cable" then take out the exshaust from the manifolds back. "i found it easy to take this out in 1 piece" Then unhook the shift linkage and electical plugs. use a tranny jack or floor jack with a wood block to slightly take some weight off the tranny, then take out the crossmember. then take off the tourque converter inspection plate. then tale off the four tourque converter bolts. then take out the six engine to tranny bolts and pull her out. On my 93 I had to remove the gas tank. But it wasn't bad, just four bolts lower it down and undo the filler tubes and fuel supply but be carful not to brake the clips on them. And also, there's a u shaped bar and shroud that goes bellow the drive shaft, it goes one way so make sure you put it on right or it while rub.

Bad ground to the dash.

The key for the door must be put in the door and unlock it. On my Lincoln the driver side lock is messed up so i lock the passenger side door and use the key to unlock it and the alarm goes off. If it does not stop disconect the battery.

The E brake pedal is to the left next to the kick panel It is vacuum operated and should release automatically when car is placed in drive as long as car has stored vacuum or is running. If it doesn't you can release it manually by lever located next to pedal . Emergency brake is built into rear calipers. Hope this Helps

ccrm module

on the trip computer it says miles/km if you press this and it converts to miles it will convert the temp from Celsius to Fahrenheit

The ~safety~ air bag on a 1991 should not be serviced by the vehicle owner. Replacement suspension air bags (springs) come with complete instructions (Arnott, StrutMasters, etc). The seller/manufacturer should gladly provide the buyer with a set even BEFORE purchasing the product. This is in their best interest to show you juyst how easy it is to install their product. If not, I'd move on to the next seller/manufacturer. Jack up your car, get to the air bag, turn the solenoid with vise grips, once the air is out turn the "fat" part at the top to unlock it. its kinda like your power steering cap on your car... it fits into place and turns to lock in. Now at the bottom of your a-arm remove the clip around the little stub that you see. kinda like a cotter pin... But like they said go to strutmasters.com and get some springs!!! 219.00 with shipping included and all instructions also. Hey also visit www.lincolnsonline.com

yes you can but its not recommended for more than one hundred miles. The output shaft bearing takes a beating without lubrication. Not trying to sound like a smart-a## but get aaa. it will save you money in the long run. hope this helps

im going on the assumption that you are referring to the belt back on the tensioner cause there is no reason to remove the tensioner to install an alt. if it is a matter of putting the belt on, make sure that the belt is routed correctly through the pulleys. then remove the belt off the alternator, put the belt on the tensioner THEN pull the tensioner back with a wrench on the tensoiner adjusting nut. slip the belt on the alternator and slowly release the wrench. i hope this was helpful
