142-8879 Oil Cooler — Cat 3034 3054C

This is an oil cooler, a heat exchanger designed to remove excess heat from the engine's lubricating oil, maintaining optimal operating temperatures and preventing premature component wear. Manufactured to meet OEM specifications, it provides efficient heat dissipation and robust construction compared to a clogged or leaking cooler that compromises lubrication. Operators may observe a rise in engine oil temperature warnings, a decrease in oil pressure, or an increase in overall engine operating temperature when this 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

The initial sign of a failing oil cooler is often an engine oil temperature warning light or gauge reading higher than normal. If ignored, the oil can overheat, leading to reduced lubrication effectiveness and increased wear on engine components. Continued operation with an ineffective oil cooler can result in severe engine damage due to excessive heat and inadequate lubrication.

Installation Tip

Thoroughly clean the mounting surfaces and ensure all O-rings and seals are properly seated before installing the new oil cooler. Do not overtighten the mounting bolts, as this can distort the cooler housing and cause leaks.

Service Note

Always change the engine oil and oil filter when replacing the oil cooler.
