International 9900/i/ix AC Driers & Compressors

Frequently Asked Questions About International 9900/i/ix AC Driers & Compressors

What is the difference between an AC drier and an AC compressor?

The AC drier, also called a receiver drier, filters moisture and debris from the refrigerant to protect the rest of the AC system, while the compressor pressurizes and circulates refrigerant through the system so it can cool the cab. Both parts work together, and a failure in either one can cause your AC system to stop cooling properly.

Will this drier or compressor fit my International 9900, 9200i, or 9400i?

Fitment can vary by model year and by the specific AC system configuration installed on your truck, so it is important to check the listed specifications, part numbers, and any cross-reference information on each product page before purchasing. If you are unsure, comparing your old part number to the one listed or reaching out to our parts team can help confirm compatibility.

How do I know if my AC drier or compressor needs to be replaced?

Common signs include weak or warm airflow from the vents, unusual noises coming from the compressor, visible oil or refrigerant leaks around the fittings, or a clogged/discolored drier. If your AC system was recently serviced and still is not cooling correctly, the drier or compressor is often one of the first components to inspect.

Do these parts come new, used, or remanufactured?

Availability varies by listing, so be sure to check each product page for details on condition. We list this information clearly so you can choose the option that best fits your budget and reliability needs.

Do I need to recharge or evacuate the AC system after installing a new drier or compressor?

Yes. Any time the AC system is opened to replace a drier or compressor, it should be properly evacuated, checked for leaks, and recharged with the correct refrigerant by a qualified technician. This helps ensure the system runs efficiently and helps prevent contamination or damage to the new component.
