PETERBILT CHARGE AIR COOLER | 377 378 385 387 388 389 | WIDE

Upgrade your heavy-duty Peterbilt with the American Radiator Wide-Core Charge Air Cooler with Bar & Plate Core and Frame, designed for 377, 378, 385, 387, 388, and 389 models. Engineered for demanding duty, this wide-body cooler delivers enhanced cooling capacity by using a robust bar & plate aluminum core, which ensures superior heat rejection and temperature stability even under high boost. Lower intake air temps result in denser charge air, better combustion, and increased horsepower—all while improving fuel efficiency.

This bar & plate charge air cooler features a reinforced structural frame that resists vibration, thermal stress, and fatigue. Its wide core construction spreads airflow evenly across the core, reducing hotspots and extending service life. Designed as a direct-fit replacement that aligns with OEM mounting points, it installs without modifications—saving time on repairs.

Optimized airflow pathways and an expanded core surface area help maintain consistent operating temperatures during extended runs and heavy loads. This wide-core design offers superb protection for your turbocharger, intake piping, and engine components, preventing performance loss due to heat soak or turbo lag.

Backed by American Radiator’s legacy of durability, the Peterbilt wide-core bar & plate charge air cooler with frame is ideal for fleets and owner-operators who demand maximum cooling efficiency, reduced downtime, and long-term reliability—mile after mile.
