Turbocharger Inlet Y-Pipe

Turbocharger Inlet Y-Pipe













Removal

1. Remove the engine cover.

2. Remove the 2 LH turbocharger inlet Y-pipe-to-exhaust manifold bolts and 2 nuts.
- Discard the nuts.





3. Remove the 2 RH turbocharger inlet Y-pipe-to-exhaust manifold bolts and 2 nuts.
- Discard the nuts.





4. NOTE: There is metal gasket between the exhaust inlet pipe and the EGR cooler.

Remove the turbocharger inlet Y-pipe-to-EGR cooler clamp.

- Discard the gasket.





5. Remove the turbocharger-to-turbocharger inlet Y-pipe clamp.





6. Carefully remove the turbocharger inlet Y-pipe assembly from the vehicle.

Installation

NOTICE: Only tighten the turbocharger inlet Y-pipe fasteners with hand tools or damage to the turbocharger inlet pipe may occur.

NOTICE: When installing the turbocharger inlet Y-pipe into the vehicle, do not bend or twist the flex bellows or damage to the flex bellows may occur.

1. 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 2 bolts and 2 new nuts.





2. Position the turbocharger inlet Y-pipe into the vehicle.

3. NOTE: Do not tighten the clamp at this time.

Position the turbocharger-to-turbocharger inlet Y-pipe clamp.





4. NOTE: Do not tighten the clamp at this time.

Install the new metal gasket on the EGR cooler and align the turbocharger inlet Y-pipe to the EGR cooler. Position the clamp.





5. NOTE: LH side shown, RH side similar.

NOTE: Do not tighten the turbocharger inlet Y-pipe-to-exhaust manifold bolts at this time.

Apply anti-seize lubricant to the turbocharger inlet Y-pipe-to-exhaust manifold bolts, then install the 4 bolts and 4 new nuts.





6. Tighten the turbocharger-to-turbocharger inlet Y-pipe clamp.
- Tighten to 12 Nm (106 lb-in).





7. Tighten the turbocharger inlet Y-pipe-to-EGR cooler clamp.
- Tighten to 6 Nm (53 lb-in).





8. Make sure the turbocharger inlet Y-pipe is correctly aligned to the exhaust manifolds. Using hand tools, alternately tighten the 4 bolts to draw the turbocharger inlet Y-pipe to the exhaust manifold. There should be an equal gap spacing between the turbocharger inlet Y-pipe and the exhaust manifold flange at the top and bottom bolts.





9. NOTE: LH side shown, RH side similar.

Alternately tighten the 4 turbocharger inlet Y-pipe-to-exhaust manifold bolts.

- Tighten to 27 Nm (20 lb-ft).





10. If loosened, tighten the 2 turbocharger inlet Y-pipe nuts at the RH to LH joint.
- Tighten to 27 Nm (20 lb-ft).





11. Check the systems for leaks.

12. Install the engine cover.
