4n-2231-2w-7590-378-3971 Oil Cooler — Cat 3204 910

This is an engine oil cooler designed to regulate the temperature of lubricating oil in Caterpillar engines. It is manufactured to meet stringent OEM quality standards, ensuring efficient heat exchange to prevent oil breakdown and maintain proper lubrication, unlike a clogged or leaking cooler. Operators may observe a rise in oil temperature, reduced oil pressure, or increased engine noise if this component is failing.

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 initial symptom of a failing oil cooler is a noticeable increase in engine oil temperature, often indicated by the temperature gauge. If ignored, the oil can degrade, losing its viscosity and protective qualities, leading to increased friction and wear on engine components. Continued operation with an ineffective oil cooler risks severe internal engine damage.

Installation Tip

Thoroughly flush the oil passages of the engine and the new cooler to remove any debris before assembly. Ensure all sealing surfaces are clean and free of damage before installing new gaskets or O-rings.

Service Note

Inspect the engine oil filter and oil pressure sensor when replacing the oil cooler.
