7n-0165-7s-6394 Oil Cooler Core — Cat 3306

This is an oil cooler core, a vital heat exchanger within the engine's lubrication system. It dissipates excess heat from the engine oil, maintaining optimal operating temperatures for engine longevity and performance. Manufactured with high-grade materials and precise fin spacing, this core ensures efficient heat transfer, unlike a clogged or damaged core which restricts oil flow and leads to overheating.

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 core might be a gradual increase in engine oil temperature during operation. If ignored, this can lead to persistent overheating, reduced oil viscosity, and potential engine damage due to inadequate lubrication. Overheating can accelerate wear on internal engine components and lead to premature engine failure.

Installation Tip

Ensure all mating surfaces are clean and free of old gasket material before installing the new oil cooler core. Use new seals and gaskets as specified for a leak-free installation.

Service Note

Flush the oil cooler lines thoroughly and replace the engine oil and filter when installing a new oil cooler core.
