How To Inflate Air Suspension On Lincoln Town Car

Air suspension reduces the tendency of the car to bounce over rougher terrain. But like all car parts, air suspension is prone to mechanical issues. Air suspension issues are especially prominent in Lincoln Town Cars.

Sinking Linkon’s are a common site everywhere. Now the question is how to inflate air suspension on lincoln town car?

The air suspension can be inflated by directly sending high-pressure air to the air springs. Lincoln Town cars start to sink, for a common reason. When the air compressor of that car is not able to pump enough air. To support the weight of the car. So bypassing the compressor is the way to go.

Still wondering how to actually stop your Lincoln Town car from sinking? Come find out in this article.

Air Suspension of Lincoln Town Car 

Lincoln town car air suspension kit is a small, separate air compressor. It is placed under the driver’s side left fender well. 

Air lines from the compressor run to the air bags. If the rear of the car drops for whatever reason, the arm is pushed up. This turns on the air compressor. The compressor then fills the air bags to level the car.

Diagnosing The Air Suspension

The lincoln Town car air suspension compressor test is really helpful. It will help you understand the condition of your car’s air compressor. The test is pretty easy if your car’s height sensor worlds properly.

The height sensor of your Lincoln Town will notify the suspension module whether it is at trim height or not. But that is if the air suspension is working normally and the ignition is also turned on.

If the suspension is at trim height, then there is nothing needed to be done. Your car is okay.

But the chances are, you are here because the suspension is below trim height. In such a situation, the suspension module starts the compressor and opens the air spring solenoids.

In this case, the compressor is unable to supply air at a high pressure. For this, the springs are not able to be filled. And the suspension is lowered.

Why Is The Lincoln Sinking?

Lincoln Town Cars were equipped with a pair of rubber air springs from the factory. These rubber air springs support the weight of the vehicle.

Due to usage and aging, the rubber air springs dry rot and eventually start leaking air. The leaky system cannot hold the air sent by the compressor.

The compressor is working to send high-pressure air to the rubber springs. You may hear the compressor running. But it cannot pump up enough air to keep the car off the ground.

The damaged and leaking rubber air springs force the compressor to overwork. This in time burns out the compressor as well.

The compressor might also be damaged due to corrosion. Moisture is retained in the compressor tray and that may cause rust.

Prior Preparations 

Before you can inflate the air suspensions, you have to make necessary preparations. We already mentioned Lincoln Town car air suspension compressor location. They are mounted below the air cleaner box.

First, you have to make sure the air suspension switch is in the ON position. The Lincoln Town car air suspension switch location is in the trunk of the car. So open the trunk for easy access to the air suspension switch.

Now you have to access the air suspension compressor. Then disconnect the high-pressure line from the drier. The compressor is not required to be moved.

From the air suspension compressor, only the high-pressure line to the drier should be removed. In order to disconnect the lines from the drier, push the orange collets. Push it https://theautoartist.com/how-to-disconnect-fuel-line/down around the line. This will release the line and you have to instantly pull it free.

You will need an air tank filled with dry air. It may be connected with a drier as well. This air tank will require an air gun conical fitting as well.

Now enter the air gun conical fitting into the high-pressure hose coming from the drier. Make a seal with it. A fitting with a rubber tip is highly recommended.

This whole procedure requires two people. One controls the air tank and pressure line. While the other deals with the car ignition and listens for the spring solenoid clicks.

Inflating the Rear Air Suspension

Now you can finally begin to inflate the air suspension. Begin by first joining the air tank fitting with the high-pressure hose. And then turn on the ignition.

The suspension module of your Lincoln will realize that the car has low trim height. It will also spontaneously start the air compressor and open the air spring solenoids.

You may be able to hear the click from the Lincoln town car air suspension solenoid. Now apply air pressure to the high-pressure hose from the air tank. You will see that the rear of the car is gradually rising.

While the car is rising, the suspension module will observe the height using the height sensor. The module waits to receive the trim height signal from the sensor. When it receives the signal,  it will close the air spring solenoid.

The air spring solenoids are turned off with a click. The suspension will also turn off the car’s air compressor. Now you have to turn off the suspension switch located in the trunk and the ignition.

After that, you have to disconnect the fitting from the high-pressure hose. You have to turn off the air tank as well. 

Now to install the high-pressure line back into the drier. To do this you have to press down the orange fitting. Next insert the hose and let go of the orange fitting. Examine the hose by carefully attempting to pull it out.

FAQs

Why Does Air Suspension Do In Lincoln Town Cars?

Air suspension reduces the tendency of the car to bounce over rougher terrain. So you can have a smoother ride. The air compressor of the Lincoln Town cars pumps air into the rear. It keeps the car from sagging or bouncing too much. This results in a more pleasant ride.

Where Is A Height Sensor Of Lincoln Town Car Located?

The height sensor helps the car maintain enough ground clearance. Passengers or cargo entering or leaving may impact the height of the car. But the sensors sense these changes in height and help make necessary adjustments. It is generally located above the rear axle housing on the driver’s side.

Where is the Air Suspension In The Lincoln Town Car?

Normally the air suspension of a Lincoln Town Car is a small, separate air compressor. It is placed under the driver’s side left fender well. Air lines from the compressor run to the air bags. If the rear of the car drops for whatever reason, the arm is pushed up.

Conclusion

And with that you know how to inflate air suspension on Lincoln town car. It is a difficult process and requires a lot of equipment. But worry not, you can do it yourself.

We have shown you how to directly sending high-pressure air to the spring solenoids. You will need an air tank, high-pressure hose, and rubber fittings for the procedure.

That’s all! Have a great day!
