When installing a new compressor for an air ride system, there are four items you need to pay attention to.

First, inspect the mounts that attach the compressor to the vehicle. The mounts are designed to isolate vibration from reaching the driver when the compressor is running. The noise might be problematic because the noise will be intermittent due to the operation of the compressor. Make sure the springs and bushing are in good condition. This replacement Wabco compressor kit includes new springs and bushings.

Second, ensure the hoses connecting to the intake and exhaust ports are clean and not damaged. Dirt and moisture inside the intake can clog internal filters and contaminate the drier inside the compressor. Also, some vehicles may have an external filter and drier assembly that should be serviced when the compressor is replaced. The hose for the exhaust port should be secure to the compressor and vehicle. If the exhaust hose is not securely attached, it could cause excessive noise when the ride height is being adjusted.

Third, the outlet on the compressor is typically a push-to-connect or push-on type fitting. To remove the plastic line, unfasten the fitting using a line wrench and remove the metal or plastic collar and pull out the line like this. Most Wabco compressors include a new fitting and plastic line that connects the compressor to the vehicle. To install the new line and fitting, press the collar into the fitting and install. Push line into the fitting until this printed line is flush with the base of the fitting like this.To connect the line to the compressor or vehicle, push it into the fitting until this printed line is flush with the base of the fitting like this. Do not attempt to cut the line without the appropriate tools. Using the wrong tools can cause the connection to leak or introduce a restriction into the system.

Fourth, inspect the electrical connectors on the vehicle. Since most compressors are mounted to a frame rail or near a wheel well, the compressor is exposed to moisture, debris and even road salt. This can cause corrosion inside the electrical connectors. This corrosion can cause thermal damage to the connector due to the increased resistance in the circuit. If the connector on the vehicle is damaged, service it with a new pigtail harness.

If you address these four items when replacing a compressor, you can be sure that when it is turned on, it will be able to generate the pressure and volume required for the air suspension to operate like new.

Andrew Markel talks air flow sensors in this video sponsored by Auto Value and Bumper to Bumper.

The theory and operation of any mass airflow sensor is pretty basic. What you have is a wire in the airstream entering the engine. It has current running through it. This current heats up the wire. As the air flows over this wire, it changes the resistance in the wire. The change in resistance shows the ECM, how much air is entering into the engine. But by heating up a wire that is in the Airstream entering the engine, even after the filter, it can have contaminants that can stick to that hot wire and cause faulty readings about the air entering into the engine. This can cause numerous codes because either it's under or over reporting the air entering the engine, and it's not very accurate. And using the oxygen sensor, the ECM can see issues with the mass airflow sensor. So what can you do both for maintenance and for service and diagnostics to confirm a mass airflow sensors functioning properly?
