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

Initial signs of a failing turbocharger include a noticeable reduction in engine power and acceleration, accompanied by increased exhaust smoke. If ignored, the turbocharger may begin to make loud whining or grinding noises, and oil consumption can increase significantly. The ultimate consequence is a complete loss of boost pressure, rendering the vehicle inoperable and potentially causing severe engine damage.

Installation Tip

Always prime the new turbocharger with clean engine oil before initial startup to ensure proper lubrication of the bearings. Avoid over-tightening exhaust manifold bolts, as this can distort the housing and lead to leaks.

Service Note

Inspect the engine's air intake and exhaust systems for leaks or blockages, and check the oil supply line for cleanliness and flow.
