Frequently Asked Questions About International LT AC Driers & Compressors

Will these AC driers and compressors fit my specific International LT model year?

Our AC driers and compressors are designed to fit International LT models from 2017 to present. However, there can be variations based on your specific engine configuration and AC system type. We recommend checking your VIN or calling our support team at 1-888-875-7787 with your truck's serial number to ensure exact compatibility. Most components will indicate whether they're for standard or high-capacity AC systems.

What's the typical lifespan of these AC components, and what are the warning signs of failure?

Quality AC compressors typically last 8-10 years or 100,000-150,000 miles with proper maintenance. Driers should be replaced every 2-3 years or whenever the AC system is opened. Watch for these failure signs: reduced cooling performance, unusual noises from the compressor (grinding or squealing), visible refrigerant leaks, clutch not engaging, or excessive moisture in the system. If your AC takes longer to cool or cycles on and off frequently, it's time for an inspection.

Can I install these components myself, or do I need special tools and certification?

While mechanically inclined individuals can physically install these components, working with AC systems requires EPA 609 certification for handling refrigerants. You'll need specialized tools including a vacuum pump, manifold gauge set, and refrigerant recovery equipment. The system must be properly evacuated and recharged with the correct amount of refrigerant (typically R-134a). Most customers find it more cost-effective to have a certified technician handle the installation to avoid damaging the new components or violating environmental regulations.

What's included with the compressor, and what additional parts might I need?

Most compressors come as bare units without the clutch assembly, though some are available as complete assemblies. You'll typically need to purchase separately: compressor oil (PAG oil specific to your system), new O-rings and seals, replacement drier (mandatory when replacing compressor), and refrigerant. We recommend also replacing the expansion valve and flushing the system to remove any debris from compressor failure. Check each product listing for what's specifically included.

Are aftermarket options reliable compared to OEM, and what brands do you recommend?

We carry both OEM and high-quality aftermarket options. Aftermarket brands like Denso, Four Seasons, and MEI have proven reliable for International LT applications, often matching or exceeding OEM specifications at a lower price point. The key difference is usually warranty length - OEM typically offers 2-3 years while aftermarket ranges from 1-2 years. For heavy-use applications or extreme climates, OEM or premium aftermarket (like Denso) is recommended. All our listed products meet or exceed original equipment specifications.
