298-4558 Oil Cooler — Cat 420E 430E

This is an oil cooler designed to regulate the temperature of the engine oil in CAT equipment. It uses engine coolant to dissipate heat from the oil, ensuring optimal lubrication and preventing thermal breakdown. A failing oil cooler may lead to elevated oil temperatures, indicated by a warning light or loss of engine power.

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 initial symptom of a failing oil cooler is a gradual increase in engine oil temperature, potentially triggering an oil temperature warning light. If left unaddressed, this can lead to accelerated engine wear due to inadequate lubrication. Prolonged operation with an ineffective oil cooler risks severe engine damage.

Installation Tip

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

Service Note

Inspect the engine coolant and oil for any signs of cross-contamination, which could indicate internal leaks within the cooler.
