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 noticeable decrease in engine power and acceleration is often the first sign of a failing turbocharger. If left unaddressed, the turbocharger may begin to consume excessive oil, leading to blue exhaust smoke and potential engine damage. Continued operation with a compromised turbocharger risks severe engine internal damage due to inadequate lubrication and combustion.

Installation Tip

Ensure the engine oil is clean and at the correct level before installation, as proper lubrication is critical for turbocharger longevity. Avoid over-tightening the oil supply or return line fittings, which can damage the threads or the lines themselves.

Service Note

Inspect the engine's air filter, intake hoses, and exhaust manifold for any signs of damage or blockage.
