239-7851 Oil Cooler — Cat C15

This Oil Cooler is a heat exchanger designed to remove excess heat from the engine lubricating oil, maintaining optimal oil viscosity and preventing thermal degradation. It is constructed with durable materials and efficient internal passages to ensure effective cooling, unlike a clogged or leaking cooler that compromises oil lubrication and engine protection. Operators may notice a significant increase in oil temperature readings, a decrease in oil pressure, or potential engine performance issues due to inadequate lubrication.

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 might be a gradual rise in engine oil temperature, especially during heavy load conditions. If the cooler becomes internally blocked, it can lead to insufficient lubrication and increased wear on engine components. A leaking cooler can result in loss of oil pressure, potentially causing severe engine damage.

Installation Tip

Ensure that all mating surfaces for the oil cooler lines and mounting points are perfectly clean and free of any old gasket material or debris. Do not overtighten the fittings, as this can damage the cooler's ports.

Service Note

When replacing the oil cooler, it is recommended to also replace the engine oil and oil filter, and inspect the oil lines for any signs of damage or blockage.
