This oil cooler is designed to regulate the temperature of the engine oil in Volvo D6E and D6D engines, preventing overheating and ensuring optimal lubrication. Constructed with durable materials and efficient heat exchange fins, it performs reliably under demanding conditions, unlike a clogged or leaking cooler that compromises oil viscosity. Operators may observe a rise in engine oil temperature warnings, a decrease in oil pressure, or visible oil leaks if this component fails.
Always verify with serial number before ordering.

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.
The first indication of a failing oil cooler might be an engine oil temperature warning light or gauge reading higher than normal. If the issue progresses, oil pressure may start to fluctuate or drop, and visible oil leaks could appear around the cooler fittings. Continued operation risks accelerated engine wear due to inadequate lubrication.
Ensure all mating surfaces for the oil lines are perfectly clean and free of debris before installation to prevent leaks. Always use new sealing washers or O-rings as specified for the connections.
When replacing the oil cooler, it is recommended to inspect the engine thermostat and flush the cooling system if necessary.
