Installation & Application Notes

Allow turbo to idle 2–3 minutes before shutdown — this circulates oil through bearings and prevents coking. Check oil feed and drain lines for blockages before fitting new turbo. Replace oil and filter when fitting new turbo — old oil contains metal particles.

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 component is a noticeable decrease in engine power and acceleration. If ignored, the turbocharger may produce loud noises, and exhaust emissions will increase. Continued operation without addressing the issue can lead to reduced engine efficiency and potential damage to the turbocharger assembly.

Installation Tip

Ensure the turbocharger's oil supply and drain lines are clear and properly connected before installation. Do not reuse the old exhaust or intake gaskets.

Service Note

Inspect the exhaust manifold and turbocharger housing for cracks or damage.
