4i-7502 Core As Oil Cooler — Cat 3116 320

This oil cooler core is a vital heat exchanger within the engine's lubrication system, designed to dissipate heat from the engine oil. Manufactured to meet precise OEM thermal transfer standards, it provides efficient cooling compared to a clogged or damaged core. Operators may notice a rise in oil temperature, increased engine noise, or a warning light for high oil temperature if this cooler core 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

The first sign of a failing oil cooler core might be a gradual increase in engine oil temperature readings. If the issue persists, the engine may start to run hotter, potentially leading to a high oil temperature warning light. Continued operation with an inefficient oil cooler risks accelerated wear on engine bearings and other critical internal components due to excessive heat.

Installation Tip

Ensure all sealing surfaces are clean and free of old gasket material before installing the new cooler core. Properly torque all mounting hardware to the manufacturer's specifications to prevent leaks.

Service Note

Inspect the engine oil and coolant for signs of contamination, and check the integrity of the oil lines when replacing the oil cooler core.
