How To Manually Fill Air Suspension

Air suspension systems are a big part of modern cars. They provide a smooth ride, improve gas mileage, and make the car more habitable in cold weather. However, air suspension can also be a big headache if it’s not properly maintained. In this blog post, we will show you how to manually fill an air suspension system and keep it running smoothly. By following these simple steps, you will be able to maintain your car’s performance and safety without having to take it in for service.

How do I manually fill my air suspension?

Air suspension is a technology that uses compressed air to raise or lower a vehicle. It’s most commonly found in luxury cars, but it’s also available in some trucks and SUVs. The system uses a reservoir of compressed air to keep the vehicle in its suspension height. When you need to adjust the suspension, you release the pressure from the reservoir and the car rises or lowers accordingly.

There are several ways to fill your air suspension:

1) Use an external compressor. This is the easiest way to fill your suspension, but it can be expensive and you may have to move your car to get access to a compressor.

2) Use a bilge pump. This method is more difficult, but it’s cheaper and you can fill your suspension using just one pump.

3) Fill your suspension using compressed air from your car’s air conditioning system. This is the slowest way to fill your suspension, but it’s also the cheapest option.

What are the consequences of not filling my air suspension?

If you don’t fill your air suspension’s reservoir, the pressure inside will increase until it ruptures. This can cause the suspension to collapse, potentially resulting in a dangerous fall. If you’re driving over rough terrain, this could also cause damage to your vehicle.

How do I know if I need to replace my air suspension?

If you notice that your air suspension is not providing the same level of support as it used to, or if it begins making unusual noises, it may be time to replace it. Here are four signs that you need to replace your air suspension:

1. Your car has a significantly rougher ride than before.
2. The springs have lost their initial bounce.
3. You’re constantly bouncing off bumps in the road.
4. The vehicle takes longer to go from a stop than it used to

How do I fill my air suspension?

The following is a guide on how to manually fill an air suspension.

1. Park the vehicle on a level surface and turn off the engine.
2. Remove the front bumper cover by pulling it down form the top of the car and then rotating it counterclockwise to remove it.
3. Use a Phillips screwdriver to unscrew the four screws that hold the air suspension control unit to the frame of the car (two on each side). Be careful not to lose these screws!
4. After unscrewing the four screws, carefully pull off the control unit from the frame of your car. Make sure to note which wires go where as you will need them later!
5. Disconnect both inflator hoses from underneath the control unit by unscrewing them from their respective brass connectors (three per hose). If you have an after-market air suspension, there is usually a quick-release valve in place that can be opened with a flathead screwdriver once disconnected (as shown in image below).
6. Carefully pour out any air that may still be in both hoses by squeezing them together until they release any accumulated air pressure (you may hear some gasps as this happens!). Once they are clear, replace both inflator hoses and screw them back on to their connectors beneath the control unit (being careful not to lose any screws again!).
7.Reattach the control unit to its frame by replacing those
