FAQ

Q: Will this charge air cooler fit my specific Cummins 4BT engine?
A: This cooler (Part #3929333 / C5262613) is specifically designed for the Cummins 4BT and 4BTA series engines. However, there are variations in mounting brackets and pipe configurations depending on the exact application (e.g., generator vs. skid steer). We strongly recommend comparing your original part number and physical dimensions (core length, width, and inlet/outlet locations) with the specifications listed above. Contact us with your engine serial number or a photo of your old cooler for 100% fitment confirmation.

Q: What are the signs that my charge air cooler needs replacement?
A: Key symptoms of a failing or damaged charge air cooler include: a noticeable loss of engine power, increased fuel consumption, excessive black smoke from the exhaust (indicating incomplete combustion), or a visible oil leak near the cooler core. You may also hear a hissing sound from a boost leak. If you suspect a leak, a simple pressure test of the air intake system can confirm the issue.

Q: What is the recommended maintenance for this part?
A: The charge air cooler is a maintenance-free component under normal operating conditions. However, during major engine overhauls or if the engine is operating in a very dusty environment, we recommend inspecting the cooler core for external debris (mud, dirt, bugs) that can block airflow. Clean the fins gently with low-pressure compressed air or water. Never use a pressure washer directly on the core, as it can damage the fins. Also, check the mounting brackets and rubber hoses for wear and ensure all clamps are tight.
