7C3039 Core As-Oil Cooler — Cat 16g 16H nA

This oil cooler core is a heat exchanger designed to dissipate heat from the engine's lubricating oil, maintaining optimal oil temperature for proper lubrication and engine protection. Manufactured to meet stringent OEM specifications, it provides efficient cooling performance superior to a damaged or clogged core, preventing oil breakdown. Operators might observe a rise in oil temperature warnings, decreased oil pressure, or potential engine overheating if this component is compromised.

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

Early signs of a faulty oil cooler core include an engine oil temperature warning light or gauge reading higher than normal. If the issue persists, the engine may experience a gradual loss of oil pressure, and the engine could begin to overheat. Prolonged operation with a compromised oil cooler risks severe engine damage due to lubricant breakdown and excessive heat.

Installation Tip

Ensure all oil passages are completely clear of debris and old sealant before installing the new core. Use new seals and gaskets, and apply them correctly to prevent oil leaks.

Service Note

Inspect the engine oil for signs of coolant contamination or sludge when replacing the oil cooler core.
