Removing
- Bring the lock carrier into service position: [1][2]Procedures
- Drain engine oil.





- Unbolt stop -1- (arrows).





- Unclip lower section -1- of starter wire mount (arrows).
- Unbolt oil return line from turbocharger at oil pan.

Vehicles with automatic transmission





- Remove bracket -1- for ATF lines (arrows).





Continuation for all vehicles
- Disconnect connector from Oil Level Thermal Sensor.
- Mark installation positions for threaded assemblies -1- and positioning sleeves -2-.
- Unbolt both engine mounts at bottom.





- Install 10-222A engine support bridge as shown.
- Remove eyelet for 2024A Engine Sling.
- Insert bolt -1- in the center bore of 2024A Engine Sling and secure with a cotter pin.
- Attach 2024A Engine Sling bolt to 10222A Engine Support Bridge spindle.
- Attach 2024A Engine Sling to sling clamps at front and rear of engine.

WARNING! Take-up hooks and pins at engine sling must be secured using securing pins (arrows) as shown in illustration.

- Lift up engine as far as possible using spindle of engine support bridge, or until the T-piece of crankshaft housing ventilation contacts the bulkhead (approximately 20 mm).





- Use 1202A engine hoist to support subframe.





- First remove front bolts -2- and -3 from left and right sides of subframe. Then remove bolt-4-.

Note: Only loosen or lower subframe at front side to avoid having to perform a wheel alignment.

Vehicles with manual transmission





- Loosen left transmission mount nut (arrow) until it is aligned with lower edge of bolt (approximately 4 turns).

Vehicles with automatic transmission





- Loosen rear bolt -2- for left transmission mount a few turns and remove front bolt -1 for left transmission mount.





Continuation for all vehicles
- Loosen rear bolt -2- for right transmission mount a few turns and remove front bolt -1 for right transmission mount.





- Slowly lower subframe using workshop crane.
- Wheel out workshop crane and swing stabilizer downward.
- Unbolt oil pan.

Notes:
^ Use 3185 flexible head spanner to loosen and tighten the rear inner oil pan bolts, and use T10058 hex ball socket to remove and drive in bolts.
^ For vehicles with manual transmission: Both rear bolts on oil pan can be reached through opening on flywheel (arrow). Turn flywheel as needed.






- Remove oil pan. It may be necessary to loosen oil pan by hitting it lightly with a rubber mallet.
- Swing oil pan to left at rear and slightly push subframe downward on left side in order to be able to swing oil pan over the subframe.
- Remove any remaining sealant from cylinder block using a scraping tool.





- Remove remaining sealant at oil pan using a rotating brush, e.g. a drill with plastic brush attachment (wear protective glasses).
- Clean sealing surface. They must be completely free of oil and grease.

Installing

Notes:
^ When installing oil pan on removed engine, make sure that oil pan is aligned with mete/ on flywheel side (i.e. oil pan projects out over engine block 0.8 mm).
^ Note expiration date for sealant.
^ The oil pan must be installed and tightened within 5 minutes after application of silicon sealant.





- Cut tube nozzle at front marking (nozzle approximately 3 mm).
- Apply silicon sealant to clean sealing surfaces of oil pan as shown. Sealant bead must:
^ be 2 to 3mm thick
^ continue to inner side in area of screw holes (arrows)

Note: Sealant bead must not be thicker than specified. Otherwise, excess sealant could get into oil pan and clog strainer in intake line of oil pump.





- Apply silicon sealant to clean sealing surface as shown in illustration.

Note: Apply sealant in area of sealing flange at rear with extra care. There are two bores in the cylinder block at the locations marked with arrows.

- Insert vertical M10 bolts into oil pan before installing the oil pan.
- Position oil pan immediately and tighten all oil pan screws lightly.
- Tighten M7 oil pan bolts in diagonal sequence to 15 Nm.
- Tighten M10 bolts between oil pan and cylinder block to 45 Nm.
- Tighten bolts between oil pan and transmission to 45 Nm.

Note: After installing oil pan, allow sealant to dry for approximately 30 minutes. Allow sealant to dry before adding engine oil.

The rest of the installation follows the reverse of the removal procedures.
- Install subframe.
