141-4109 Oil Cooler Core — Cat 3512

This Oil Cooler Core is a heat exchanger designed to regulate the temperature of engine oil within Caterpillar engines and trucks. Constructed from durable materials engineered to withstand high oil pressures and temperatures, it efficiently dissipates heat, unlike a clogged or damaged core that compromises lubrication effectiveness. Operators might notice a significant increase in oil temperature warnings, a drop in oil pressure, or a general overheating of the engine when this component begins to fail.

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 is often an elevated oil temperature gauge reading or an oil temperature warning light. If not addressed, the engine oil can overheat, leading to reduced viscosity and inadequate lubrication, potentially causing increased wear on internal components. The ultimate risk is severe engine damage due to overheating and lubrication failure.

Installation Tip

Ensure all sealing surfaces for the oil cooler lines are perfectly clean and that new O-rings or gaskets are used to prevent oil leaks. Do not overtighten the mounting bolts, as this can deform the cooler core or strip the threads.

Service Note

Flush the oil cooler lines and inspect the engine oil filter for debris when replacing the oil cooler core.
