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

A failing component will first manifest as a loss of engine power and sluggish acceleration. Continued use can lead to persistent exhaust smoke and audible turbocharger noise. The risk of reduced engine efficiency and potential damage to other engine components increases if the issue is not addressed.

Installation Tip

Ensure that all oil feed and drain lines are clean and unobstructed prior to installation. Do not reuse old gaskets or seals, as this can lead to leaks and performance issues.

Service Note

Check the air filter, intake hoses, and exhaust system for restrictions or leaks.
