4w-4955 Oil Cooler — Cat Engine 3516B

This is an oil cooler designed to regulate the temperature of the engine oil, ensuring optimal lubrication and performance. Manufactured to strict standards, it provides efficient heat dissipation, unlike a clogged or damaged cooler that can lead to overheating and reduced oil viscosity. Operators may notice an increase in engine temperature or a drop in oil pressure if this oil cooler fails.

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 elevated engine oil temperature gauge reading is a common initial symptom of a failing oil cooler. If the problem persists, oil pressure may begin to drop, indicating the oil is too thin from overheating. Prolonged operation under these conditions can lead to severe engine wear and potential seizure.

Installation Tip

Thoroughly flush the oil system to remove any debris before installing the new oil cooler. Ensure all O-rings and seals are properly seated and lubricated to prevent leaks.

Service Note

When replacing the oil cooler, it is crucial to inspect the engine oil for any signs of coolant contamination or metal particles, which could indicate other internal engine issues.
