FAQ'S

What Kenworth models are your charge air coolers compatible with?
Our coolers support many Kenworth models—such as W900, T680, T800—offering exact inlet/outlet alignment and mounting dimensions for seamless integration.

What’s the difference between bar & plate and tube & fin charge air cooler designs?
Bar & plate designs are more rugged and resist clogging or fatigue under heavy-duty use. Tube & fin units offer lighter weight and effective heat transfer in less extreme applications.

How do I select the correct charge air cooler for my Kenworth engine?
Match the original cooler’s dimensions, airflow capacity, and port layout. Use OEM part numbers or reference your engine model to find a precise replacement.

Can I replace just the cooler and reuse existing hoses and clamps?
Yes — if your hoses, clamps, and ducting are still sound. But for optimal performance and leak prevention, many technicians install a full kit with fresh hoses and hardware.

What signs indicate my Kenworth charge air cooler is failing?
Watch for symptoms such as boost loss, poor throttle response, elevated intake temperatures, exhaust smoke, or visible oil leaks or damage to the cooler core.
