Removal and installation the oil pan (Opel Corsa C)

Engines Z10XE(P)/Z12XE/Z14XEP

1. Remove the multi-rib belt cover and (with appropriate equipment) engine crankcase protection (see Section 5).

2. Drain the engine oil from the oil pan (See Chapter 1), replace the sealing gasket and tighten the drain plug to the required torque (see Specifications).

3. Disconnect the catalytic converter lambda probe wiring connector and release the exhaust system exhaust tract from the two damping holders. Loosen the 3 nuts and disconnect the system inlet pipe from the catalytic converter. Using improvised materials (for example, wire), tie it to the left beam of the subframe.

4. Remove the 3 bolts securing the oil pan to the transmission (see accompanying illustration), and then another 16 bolts (on ZIOXE(P) engines - 14 bolts) fastening to the engine and remove the pan.



5. Before installing the pan, clean all mating surfaces from the remains of old gaskets. Install all removed components in the reverse order of their removal, do not forget to replace all gaskets. When installing the pan, tighten all mounting bolts by hand, and then tighten them with the required force (see Specifications).

Engines Z14XE/Z16SE

6. Disconnect the cable from the negative terminal of the battery (see Chapter 5).

7. Raise the car on a lift, drain the engine oil from the crankcase (see Chapter 1). Before screwing in the drain plug, do not forget to replace the gasket.

8. Remove the multi-rib belt cover (see Section 5). Disconnect the lambda probe wiring and the exhaust system (see Chapter 4).

Note: Only the front part of the system can be released from the holders and disconnected. In this case, it must be tied to the supporting parts of the car using wire.

9. Remove the 2 rubber plugs and the bolts shown in the accompanying illustration that secure the oil pan to the transmission and to the oil pump, and then the 12 bolts that secure the oil pan to the engine. Using a suitable tool, pry the oil pan off.



10. Before installing the tray, clean all mating surfaces from any remaining sealant and pre-thread all holes.

11. Apply a bead of sealant (gray color) 2.5-3.5 mm thick on the surfaces indicated in the accompanying illustration and install the tray in place.

Attention: Installation must be completed no later than 10 minutes after applying the sealant!

12. Installation of the remaining components is carried out in the reverse order of their removal.

Z18XE Engine

13. In principle, the procedure for removing the oil pan on this engine is exactly the same as on the Z14XE/Z16SE engines (see above). However, due to the specifics of the engine layout, additional operations are required to gain access to the pan.

14. Remove the rear and then the front engine mounts (see Section 18).



15. Suspend the engine using the special equipment kit MKM-883 or using other winch-type lifting equipment (see Section 19). Remove the right engine mount (see Section 5).

16. Using the installed equipment, raise the engine high enough to access the oil pan and remove the oil pan.

17. Installation is carried out in reverse order.

Z13DT Engine

18. Perform the operations described for this engine in Section 8 up to and including the point of disconnecting the catalytic converter from the turbocharger (paragraphs 86-94).

Note: It is not necessary to set the TDC position and remove the crankshaft pulley.

19. Disconnect the oil level sensor wiring. Unscrew the 5 fastening bolts and remove the reinforcing element (see accompanying illustration).

Note: The mounting bolts are of different lengths, please note or mark their installation positions.

20. Remove 13 bolts and 2 nuts securing the pan, use tool KM-J-37228 (see illustration 12.19), separate and remove the pan from the engine.

21. Before installing the tray, clean all mating surfaces from any remaining sealant and pre-thread all holes.

22. Apply a bead of sealant (Locktite 5900) 2.5-3.5 mm thick on the surfaces indicated in the accompanying illustration and install the tray in place.

Attention: Installation must be completed no later than 10 minutes after applying the sealant!

23. Installation of the remaining components is carried out in the reverse order of their removal.

Engines Y17DT(L)/Z17DTH

24. Disconnect the negative battery cable, remove the oil dipstick, raise the vehicle on a lift and remove the multi-rib belt cover (see Section 5).

25. Remove the oil filter, drain the engine oil from the oil pan (see Chapter 1), do not forget to replace the drain plug sealing washer.

26. Loosen the 3 nuts and disconnect the exhaust pipe from the catalytic converter (see Chapter 4). Move the exhaust tract to the side and tie it to the supporting parts of the body using wire. If necessary, use the help of an assistant.

27. Unscrew 2 bolts and disconnect the engine oil level dipstick tube.

28. Remove 15 bolts securing the bottom of the pan (see accompanying illustration) and, using the appropriate tool (for example, with a spatula or with the KM-J-37228 device) pry it up and away from the top of the tray.



29. Removing the upper crankcase on a Z17DTH engine may require removing the front engine mount (see section 19).



30. Disconnect the engine oil level sensor wiring connector. Remove the 14 bolts securing the upper part of the oil pan to the engine block.

Note: The mounting bolts are of different lengths, please note or mark their installation positions.

31. Remove the 4 bolts securing the upper part of the pan to the transmission (see accompanying illustration) and, using a suitable tool, separate the pan from the engine block. Then unscrew the 2 bolts and separate the intermediate support of the drive shaft. Remove the pan.



32. Before installing the pan, clean all mating surfaces from the remains of old gaskets. Installation of all removed components is carried out in the reverse order of their removal, do not forget to replace all gaskets. The upper and lower parts of the pan are installed on the sealant (gray color).
