Shop International 4700 - 4900 Charge Air Coolers

International 4700-4900 Charge Air Coolers

The charge air cooler (CAC), also known as an intercooler, is a vital part of your International 4700 or 4900 diesel engine system. It works by cooling the compressed air from your turbocharger before it enters the engine. Cooler air means denser air, which improves combustion, boosts power, and increases fuel efficiency. If your CAC isn't performing like it should, your truck's performance, emissions, and fuel economy all take a hit.

What Does a Charge Air Cooler Do?

The charge air cooler on a diesel engine reduces the temperature of turbocharged air before it enters the intake manifold. This cooled air helps: - Improve horsepower and torque. - Reduce engine knock and stress. - Increase overall engine efficiency. - Lower emissions. It's a critical part of your intercooling system that ensures your turbocharged engine stays within safe operating temps, especially under heavy loads or long hauls.

Signs You Need a Replacement Charge Air Cooler

A bad or leaking CAC can lead to: - Loss of power and poor acceleration. - Increased exhaust smoke. - Higher fuel consumption. - Excessive heat in the engine bay. - Check engine light or fault codes related to boost pressure. A damaged CAC can also allow hot, unfiltered air or oil-contaminated air into the engine, potentially leading to long-term damage.

Frequently Asked Questions About International 4700-4900 Charge Air Coolers

Will these charge air coolers fit my specific International 4700 or 4900 model year?

Our charge air coolers are designed to fit International 4700 and 4900 series trucks typically from model years 1989-2001. However, compatibility can vary based on your specific engine configuration (DT466, DT530, T444E) and whether you have a conventional or COE cab style. We recommend checking your current cooler's part number or contacting us with your VIN to ensure proper fitment before ordering.

What's the difference between aluminum and plastic tank charge air coolers, and which should I choose?

Aluminum tank coolers offer superior durability and heat dissipation, making them ideal for heavy-duty applications or hot climates. They typically last longer but cost more upfront. Plastic tank coolers are more affordable and work well for standard applications, but may need replacement sooner in extreme conditions. Most customers choose based on their duty cycle - aluminum for severe service or high-mileage operations, plastic for lighter duty or budget-conscious repairs.

Can I install a charge air cooler myself, or do I need a professional mechanic?

Installation typically takes 2-4 hours for someone with moderate mechanical experience. You'll need basic hand tools, possibly a hoist for easier access, and should expect to drain and refill your cooling system. Common challenges include tight clearances around mounting brackets and ensuring proper hose connections. Many customers successfully complete DIY installations, but if you're uncomfortable working with cooling systems or pressed for time, professional installation is recommended.

How do I know if my charge air cooler needs replacement versus just cleaning?

Signs that indicate replacement rather than cleaning include: visible cracks or holes in the core, separated tanks, excessive oil in the cooler (indicating turbo seal failure), or pressure testing that shows leaks above 3-5 PSI loss. If your boost pressure has dropped more than 2-3 PSI from normal or you're seeing black smoke and power loss despite cleaning, replacement is likely needed. A simple pressure test at 30 PSI can help determine if repair or replacement is the best option.

What warranty coverage comes with these charge air coolers, and what does it include?

Most of our International 4700-4900 charge air coolers come with a 1-2 year manufacturer warranty covering defects in materials and workmanship. This typically excludes damage from improper installation, contamination, or physical impact. Some premium brands offer extended warranties up to 3 years. Always register your purchase and keep receipts, as warranty claims require proof of purchase and may need photos showing the failure wasn't caused by external factors.
