This is an engine oil cooler designed to regulate the temperature of the engine oil, preventing it from breaking down under high operating temperatures. It is manufactured to meet Volvo's exacting standards for heat transfer efficiency and durability, ensuring optimal oil viscosity and lubrication compared to a clogged or leaking unit. A failing oil cooler can lead to elevated oil temperatures, reduced lubrication effectiveness, and potential engine damage.

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 primary symptom of a failing oil cooler is a noticeable increase in engine oil temperature, often indicated by the temperature gauge. In severe cases, oil may appear discolored or burnt, and the engine may run hotter than usual. Prolonged operation with a compromised oil cooler can lead to accelerated wear on engine components due to inadequate lubrication.

Installation Tip

Thoroughly flush the engine oil passages and cooler lines to remove any debris before installing the new oil cooler. Ensure all sealing surfaces are clean and that new O-rings or gaskets are used.

Service Note

It is recommended to replace the engine oil and oil filter when installing a new oil cooler.
