7s-6395 Oil Cooler Core — Cat 3306 950

This is a CAT Oil Cooler Core, a vital part of the engine's lubrication system that dissipates heat from the engine oil. Manufactured to meet OEM quality standards, it ensures efficient cooling and prevents oil degradation, unlike a clogged or damaged core. Operators might observe a rise in engine oil temperature, reduced engine power, or warning lights related to oil pressure or temperature.

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

A primary symptom of a failing oil cooler core is an elevated engine oil temperature gauge reading. If the issue persists, the engine may experience a loss of power due to oil breakdown and increased friction. Prolonged operation with an ineffective oil cooler can lead to severe internal engine damage.

Installation Tip

Ensure all sealing surfaces are clean and free of old gasket material before installing the new oil cooler core. Do not overtighten the mounting bolts, as this can damage the core or its seals.

Service Note

Inspect the engine coolant level and condition, as well as the oil filter and oil pressure sensor, when replacing the oil cooler core.
