356-3519 Turbocharger — Cat D3K2 D4K2

This turbocharger is a forced induction device that increases engine power by compressing intake air using exhaust gases. It is engineered for optimal airflow and durability, ensuring efficient combustion and improved performance. A failing turbocharger will exhibit a loss of power, unusual noises, and excessive smoke from the exhaust. Operators may notice a significant reduction in acceleration, a whining or whistling sound from the engine bay, and black or blue smoke.

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

A common initial symptom of turbocharger failure is a noticeable loss of engine power, especially under load. This can escalate to audible noises like whining or grinding, and excessive smoke from the exhaust. Continued operation with a faulty turbocharger risks internal engine damage from oil starvation or debris.

Installation Tip

Always prime the new turbocharger with clean engine oil before installation to ensure lubrication upon initial startup. Do not reuse the old oil feed and drain lines, as they may be clogged or damaged.

Service Note

Inspect the engine oil system, including the oil pump and filter, and check the exhaust and intake systems for leaks when replacing the turbocharger.
