Turbocharger, Removing And Installing, 3.0L Engine: Installing
Install in reverse order of removal and note the following:
- When installing a new turbocharger compare the old and new components and if necessary reposition the attachments. Refer to OVERVIEW - TURBOCHARGER, 3.0L ENGINE .
- Replace the screw-type clamp and oil return line after removal.
- When installing a new turbocharger replace the coupling and screw-type clamp.
- Replace seals, gaskets, O-rings and self-locking nuts after disassembly.
- Replacing the stud bolts.
- Fill the turbocharger with engine oil at the oil supply line connection.
- Secure all hose connections with hose clamps that match the ones used in series production. Refer to the Parts Information.
- Check the vacuum hoses for damage before the assembly and replace if necessary.
- Used coolant cannot be used again.
If the Turbocharger was Replaced
-- Assemble the new coupling -1- with a new screw-type clamp -2- on the turbocharger -3- as shown.
-- Tighten the screw-type clamp -2- until the turbocharger can be moved on the turbocharger.
Continuation for All
-- Bring the oil return line -1- in the installation position and secure using the clip -arrow-.
-- Bring the turbocharger into the installation position and at the same time guide the oil return line to the cylinder block.
-- Tighten the stud bolts and nuts -arrows-.
-- Install the stud bolts -arrows- and tighten them.
-- Tighten the nuts -3-.
If the Turbocharger was Replaced
-- Tighten the screw-type clamp at the same time push the coupling by hand in the direction of the -arrow-.
- The force must have an effect at the right angle to the coupling -arrow-.
-- When tightening pay attention that the flange contour of the coupling -1- is positioned flush to the contour on the turbocharger turbine housing.
Controlling the correct installation -arrow- of the coupling -1- is possible from above via the visible area on the screw-type clamp.
Further installation is the reverse order of removal.
-- Install the upper air duct pipe. Refer to AIR DUCT PIPE, REMOVING AND INSTALLING .
There may be additional procedures depending on the model. Refer to TURBOCHARGER, REMOVING AND INSTALLING .
-- Fill the coolant. Refer to COOLANT, DRAINING AND FILLING .
-- Tighten the nuts -item- 15 and -item- 20. This step is necessary to compensate for the shrinkage of the turbocharger compound.
-- Install the catalytic converter or catalytic converter with particulate filter. Refer to CATALYTIC CONVERTER, REMOVING AND INSTALLING .
-- Check the oil level. Refer to ENGINE OIL .
-- Install the heat shield and engine cover. Refer to ENGINE COVER, REMOVING AND INSTALLING .
After installing the turbocharger, let the engine idle for approximately one minute without increasing the engine speed. This ensures adequate oil supply to the turbocharger.
