FAQ

Q: How do I confirm this oil cooler fits my Caterpillar E320C?
A: First, visually inspect your existing oil cooler for the OEM number 34339-03100. If that number matches, this unit is a direct replacement. Additionally, check that your machine is powered by the Mitsubishi S6K diesel engine. If you have a different engine model (e.g., Caterpillar 3066), this part will not fit.

Q: What is the installation procedure for this oil cooler core?
A: Installation involves draining the engine oil and coolant, removing the old cooler assembly, and replacing it with the new core. It is critical to replace all gaskets and o-rings during installation to prevent leaks. We recommend consulting your machine’s service manual for specific torque settings and procedures. After installation, check for leaks before returning the machine to service.

Q: How can I maintain this oil cooler for maximum lifespan?
A: Regular maintenance is key. Ensure the radiator and oil cooler fins are cleaned of debris (mud, dust, chaff) during routine service to maintain airflow. Use the correct viscosity engine oil and replace it per the manufacturer’s schedule, as dirty oil can clog the cooler’s internal passages. Periodically inspect for physical damage or fin corrosion, especially in harsh environments.
