Frequently Asked Questions About International 4700-4900 Heat & AC Parts

Will these AC parts fit my specific International 4700 or 4900 model year?

Our heat and AC parts are designed to fit International 4700 and 4900 models from 1989 through 2003. However, there were mid-year changes in some model years that can affect compatibility. We recommend checking your VIN or calling our technical support team at 1-888-875-7787 with your truck's model year and VIN to ensure proper fitment. Pay special attention if you have a 1999-2000 model, as these years had significant HVAC system updates.

What's the difference between OEM and aftermarket AC compressors, and which should I choose?

OEM compressors typically last 8-10 years and come with factory warranties, while quality aftermarket units offer 70-80% of OEM lifespan at about half the cost. Our aftermarket compressors from brands like Four Seasons and UAC feature new (not remanufactured) components and include necessary O-rings and oil. For trucks with over 300,000 miles or if you're on a budget, aftermarket is a solid choice. Choose OEM if you need maximum longevity or operate in extreme conditions year-round.

Can I install these heater cores and AC components myself, or do I need a shop?

Heater core replacement typically requires 4-6 hours and involves removing the dashboard in most 4700-4900 models. You'll need basic hand tools, trim removal tools, and ideally AC refrigerant recovery equipment. While experienced DIYers can handle blower motors and cabin filters (30-45 minute jobs), we recommend professional installation for compressors and evaporators due to refrigerant handling requirements and the need for proper system evacuation and recharging.

Why do heater cores fail so frequently on these trucks, and how can I prevent it?

The 4700-4900 series is notorious for heater core failures every 5-7 years due to electrolysis from mixed coolant types and debris accumulation. Prevention includes annual coolant flushes with distilled water, using only the recommended coolant type (typically green ethylene glycol), and installing an in-line coolant filter. Signs of impending failure include sweet smell in cab, windshield fogging, and coolant loss without visible leaks.

What other parts should I replace when doing AC repairs?

When replacing major AC components, always change the receiver/dryer ($30-50) and expansion valve ($25-40) to prevent contamination of your new parts. If replacing a compressor, flush the entire system and replace the condenser if it shows any signs of restriction. Don't forget new O-rings and proper PAG oil - using the wrong oil type is a leading cause of premature compressor failure. Most complete AC jobs also benefit from new belt tensioners and serpentine belts while you have access.
