Charge Air Coolers

At American Radiator, we specialize in aftermarket charge air coolers (CACs) for heavy-duty trucks, semi-trucks, and farm equipment. Drivers often ask: What does a charge air cooler do? It lowers the temperature of compressed air from the turbocharger before it enters the engine, improving fuel efficiency, reducing emissions, and extending engine life.

Another question is: Are aftermarket charge air coolers reliable? Absolutely. Our CACs are engineered to match or exceed OEM performance and are backed by strong warranties. With warehouse-direct pricing and same-day shipping, fleets save money and avoid downtime.

We offer two dependable options: standard tube-and-fin coolers with a two-year unlimited mileage warranty, and bar-and-plate severe duty coolers with a lifetime warranty—perfect for demanding trucking, ag, and construction applications. Popular replacements include Freightliner, International, Mack, Peterbilt, and more.

Fleet managers also ask: How can a charge air cooler save money? By preventing turbo and engine damage, CACs reduce costly repairs and keep trucks on the road longer.

Since 1976, American Radiator has been a trusted supplier of charge air coolers and repair services, delivering durability, savings, and reliable performance nationwide.

FAQ'S

What does a charge air cooler do on a semi-truck?
A charge air cooler (CAC) reduces the temperature of compressed air from the turbocharger before it enters the engine, improving fuel efficiency, horsepower, and emissions compliance.

How do I know if my charge air cooler is failing?
Common signs of a failing CAC include reduced engine power, overheating, poor fuel economy, whistling noises, or visible leaks. Regular inspections help prevent costly downtime.

Are aftermarket charge air coolers as reliable as OEM?
Yes. High-quality aftermarket charge air coolers, like those from American Radiator, are engineered to meet or exceed OEM standards while offering cost savings and strong warranties.

What is the difference between a standard and bar & plate charge air cooler?
Standard charge air coolers use tube-and-fin construction, while bar & plate designs offer increased durability and longer service life, making them ideal for severe-duty applications.

We recommend inspection every 6–12 months or sooner if the vehicle experiences heavy workloads. Replacement depends on mileage, operating conditions, and signs of wear.
