International 9900/i/ix Charge Air Coolers

Frequently Asked Questions About International 9900/i/ix Charge Air Coolers

What does a charge air cooler do on my International 9900/i/ix?

The charge air cooler, also called an intercooler, cools the compressed air coming from the turbocharger before it enters the engine intake. Cooler, denser air improves combustion efficiency, helps the engine produce more consistent power, and reduces strain on internal components. A properly functioning charge air cooler is essential to keeping your engine running at peak performance and within safe operating temperatures.

How do I know if my charge air cooler needs to be replaced?

Common signs of a failing charge air cooler include a noticeable loss of power, increased black smoke from the exhaust, boost leak codes, visible oil residue around the fins or end tanks, and coolant or oil contamination inside the unit. If you notice any of these symptoms, it is a good idea to inspect the cooler for cracks, leaks, or damaged fins before they lead to more serious engine issues.

Will this charge air cooler fit my specific International 9900/i/ix model year?

Charge air coolers can vary by model year, engine configuration, and cab style even within the 9900/i/ix lineup. Always check the listed specifications, part number, and fitment notes on each product page, and compare them against your truck's VIN or existing unit before ordering. If you are unsure, our team can help confirm fitment based on your truck's details.

Are these charge air coolers new, used, or reconditioned?

We offer a range of options depending on availability, including new aftermarket units and quality used take-off parts. Each product listing specifies the condition of the part, so you can choose based on your budget and preference. Used units are inspected for cracks, leaks, and structural integrity before being listed for sale.

What should I check during installation to avoid future problems?

Before installing a charge air cooler, inspect all mounting brackets, hoses, and clamps for wear or damage, and replace any that are cracked or brittle. After installation, it is important to pressure test the system to check for leaks and confirm there are no boost leaks at the connections. Taking these extra steps helps ensure a proper seal and extends the life of your new charge air cooler.
