Installation and Care

  • Find out why the old turbo failed before installing the new one. Oil starvation or contaminated oil will destroy the replacement the same way.
  • Change the engine oil and filter. Flush or replace the oil feed line.
  • Inspect the nozzle-ring assembly and VGT linkage for free movement before reassembly. Follow the turbocharger service procedure during installation.
