Inspection
Check turbine and compressor wheels for cracking and other
damage. Make sure turbine and compressor wheels turn smoothly. Check
for oil leakage from turbocharger assembly. Check for proper wastegate
valve operation. See SYSTEM & COMPONENT TESTING article.
Installation
1) To install, reverse removal procedure. Before oil pipe
flare nut (above turbocharger) is installed, pour clean engine oil
into turbocharger. Ensure oil and air hoses are properly installed and
securely clamped.
2) Use new gaskets. Adjust accelerator cable (if necessary).\
Refill engine oil and coolant. Check for oil and coolant leaks.
Tighten all bolts to specification. See TORQUE SPECIFICATIONS table.
