1838115 Core As-Oil Cooler — Cat 320C

This oil cooler core is a vital heat exchanger designed to reduce the temperature of the engine oil, ensuring proper lubrication and preventing thermal breakdown. It is manufactured to meet high-quality standards, providing efficient cooling and durability superior to a corroded or clogged core. Operators might notice elevated oil temperatures, increased oil pressure, or a potential loss of lubrication if this component fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

An early symptom of a failing oil cooler core might be a gradual increase in engine oil temperature readings. If the issue progresses, the oil may become too thin, leading to increased wear on engine components and potential oil pressure warnings. A severely compromised oil cooler core can lead to insufficient lubrication and significant engine damage.

Installation Tip

Always use new O-rings and seals when installing the oil cooler core to prevent leaks. Ensure the mounting surfaces are perfectly clean and flat to achieve a proper seal.

Service Note

Inspect the engine oil for signs of coolant contamination and check the radiator and coolant level during oil cooler core replacement.
