Removal And Installation: Turbocharger: Installing

WARNING: This page is about a different car, the 2013 Volkswagen Jetta and 2012 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

If mechanical damage is found on the turbocharger, for example, a destroyed compression wheel, it is not enough to just replace the turbocharger. Perform the following steps to prevent subsequent damage.

Clean all oil lines.
Change the engine oil and the oil filter.
Check the air filter housing, the air filter element and the intake hoses for contamination.
Check the entire charge air circuit and cooler for contamination.

If contaminants are found in the charge air circuit, the circuit must be cleaned and the cooler replaced if necessary.

The oil supply line must be replaced when installing a new turbocharger.

Tightening specifications, refer to TURBOCHARGER COMPONENT OVERVIEWS .

Install in reverse order of removal. When doing this note the following:

Hose connections and charge air system hoses must be free of oil and grease before installing. Sealing ring and sealing surfaces must only be lightly oiled with connector couplings. Refer to CHARGE AIR HOSE AND PIPE, DISCONNECTING AND CONNECTING .
Install only approved clamps for securing hose connections.
Charge air hose connecting and disconnecting, refer to CHARGE AIR HOSE AND PIPE, DISCONNECTING AND CONNECTING .
Always replace seals, gaskets and self-locking nuts.
Lubricate the stud bolts on the exhaust manifold with hot bolt paste.
Add oil to the turbocharger through the oil supply line connecting piece.
After installing the turbocharger, let the engine idle for approximately 1 minute without increasing the engine speed. This ensures adequate oil supply to the turbocharger.
The coolant return line . Coolant Return Line must be installed together with turbocharger.
