Y-Pipe Removal & Installation

I found this while googling how to change a Y-pipe out and thought I'd share:


Item Specification
High Temperature Nickel Anti-Seize Lubricant
XL-2 ESE-M12A4-A

NOTE: The names turbocharger inlet Y-pipe and turbocharger adapter pipe refer to the same component.
Item Part Number Description
1 6K682 Turbocharger
2 8287 Clamps
3 W300006 Turbocharger inlet Y-pipe bolt (2 required)
4 W300051 Turbocharger inlet Y-pipe nuts (6 required)
5 6K854 Turbocharger inlet Y-pipe (LH)
6 W300013 Turbocharger inlet Y-pipe bolts (4 required)

With the vehicle in NEUTRAL, position it on a hoist.
Remove the turbocharger.
Remove the fuel injector control module (FICM).
Remove the retaining nuts and the rear FICM bracket from the LH valve cover.
graphicNOTE: There is a metal gasket between the exhaust inlet pipe and the exhaust gas recirculation (EGR) cooler.
Remove the turbocharger inlet Y-pipe-to-EGR cooler clamp by opening up the clamp, pushing the clamp down, positioning the bottom of the clamp toward the EGR cooler and then positioning the top of the clamp toward the EGR cooler.

Remove the turbocharger inlet Y-pipe.

NOTE: When installing the turbocharger inlet Y-pipe into the vehicle, do not bend or twist the flex bellows.
NOTE: Only tighten the turbocharger inlet Y-pipe fasteners with hand tools.
NOTE: Do not tighten the nuts at this time.
NOTE: Apply anti-seize lubricant to the turbocharger inlet Y-pipe bolts.

If the turbocharger inlet Y-pipe was separated, install the gasket and loosely install the bolts and nuts.

NOTE: Do not tighten the clamp at this time.

Install the metal gasket on the EGR cooler and align the turbocharger inlet Y-pipe to the EGR cooler. Position the clamp.
NOTE: Do not tighten the nuts at this time.
NOTE: LH shown, RH similar.

Apply anti-seize lubricant to the turbocharger inlet Y-pipe bolts, then install the bolts and nuts.

Install the turbocharger.

If loosened, tighten the turbocharger inlet Y-pipe nuts at the RH to LH joint.
Tighten to 27 Nm (20 lb-ft).
