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

The first sign of a failing turbocharger is often a significant reduction in engine power, especially under load. This may be accompanied by increased exhaust smoke and unusual noises like whistling or grinding. If left unaddressed, the turbocharger can fail completely, leading to a total loss of engine power and potential damage to the engine from debris.

Installation Tip

Ensure the engine oil and oil filter are changed before installation and that the new turbocharger's oil inlet passages are pre-lubricated. Avoid over-revving the engine immediately after installation, allowing the turbocharger to lubricate properly.

Service Note

Inspect the air intake system and exhaust manifold for leaks or restrictions when replacing the turbocharger.
