Cat 3306 Oil Cooler Core — Reman Parts

A remanufactured (reman) Cat 3306 oil cooler core is a rebuilt replacement part that has been restored to OEM-equivalent performance standards. It replaces the original core that transfers heat from engine oil to the coolant, helping maintain safe operating temperatures and preventing engine damage from overheating.

The Cat 3306 engine is found in a wide range of Caterpillar equipment including bulldozers, motor graders, wheel loaders, excavators, scrapers, and generator sets. The oil cooler core is a critical component in all these applications to maintain proper engine oil temperature during heavy-duty operation.

Signs that your Cat 3306 oil cooler core may need replacement include rising engine oil temperatures, oil contamination in the coolant (milky appearance), coolant mixing with oil, or visible external leaks and damage to the core. Regular inspection during scheduled maintenance can help catch failures early and prevent costly engine damage.
