Note. This is a difficult operation. Please read this entire paragraph before proceeding. Make sure you have a lifting device, jack and props of sufficient capacity. During disassembly, make notes to yourself so that the routing of wires and hoses, the location of brackets and other "little things" did not cause you any difficulties during assembly.
Withdrawal
1. Remove the hood as directed in chapter 11.
2. Relieve pressure in the fuel system (see chapter 4A). Disconnect the negative cable from the battery (see chapter 5A)
3. Drain the coolant (see chapter 1).
4. Drain engine oil (see chapter 1).
5. Separate from the engine and remove the manual transmission (see chapter 7A) or automatic transmission (see chapter 7B).
6. If the lifting device you have is not high enough to remove the engine from the raised vehicle, lower it to the ground.
7. To clear the working area and improve access to the engine, temporarily support it from below with a trolley jack. Remove the hoist or other lifting device that was used to support the engine when the transmission was removed from the engine and set aside.
Attention! Before disconnecting and removing the hoist, make sure that the jack is securely supporting the engine from below.
8. Remove the radiator (see chapter 3).
9. On a model with a 4-cylinder M43TU engine, remove the ignition coils as indicated in chapter 5B, and the secondary air injection pump as specified in chapter 4B.
10. Remove the air cleaner and air flow sensor (see chapter 4A).
11. On the rear side of the engine compartment, remove the air duct of the ventilation and interior heating system. To do this, follow these steps (pic. 4.11, a, b).
- A) Remove the cabin air filter cover by turning its retainers 90°counterclockwise. Pull the filter out of the housing.
- b) Unfasten the four latches of the wiring box and remove the sleeves with wires from the box.
- V) Remove the four screws and pull the cabin filter housing forward.
- G) In the left rear corner of the engine compartment, pull off the seal, turn the two latches counterclockwise and slide the trim panel slightly forward.
- d) Turn out two screws and remove an air duct.
12. On a 4-cylinder engine, loosen the power steering pump pulley bolt and remove the accessory drive belt (see chapter 1).
13. Turn away nuts of fastening of a reservoir of a reserve liquid of a steering booster and move a reservoir aside, without disconnecting hoses from it (pic. 4.13).
14. Remove the A/C compressor from the engine, free its tubes and slide the compressor out of the workspace, securing it carefully.
Attention! Do not disconnect the air conditioning piping - cautions in this regard are given in chapter 3.
15. Remove the power steering pump as indicated in chapter 10. Without disconnecting the pipelines, move it to the side. If necessary, disconnect the hose going to the rack housing from the mounting to the steering gear mount.
16. Disconnect the ground rails from the engine mount brackets.
17. Remove the intake manifold from the engine (see chapter 4A).
18. On the 4-cylinder N42 engine, disconnect the hose from the secondary air injection valve on the right side of the cylinder head. Loosen the valve nuts and remove the valve from the engine.
19. On all engines, disconnect the vacuum hoses and hoses of the cooling system. Remember their padding.
20. In the safety circuits when removing the engine, remove the oil dipstick tube. Remove the o-ring from the tube. When installing the tube in place, the ring must be replaced.
21. Disconnect all electrical connectors. related to the engine. Note the wiring and connector positions.
22. Release the engine wiring by unscrewing the bracket mounting bolts and move it away from the engine. On an N42 4-cylinder engine, the alternator may need to be removed to remove the wires from the engine.
23. Check that all wires have been removed from the engine and that they do not interfere with its removal.
24. Check up, whether on the engine of the hoses and pipelines attached to it which could interfere with its removal remains.
25. Rearrange the lifting device, placing it above the engine. Hook the hoist slings to both engine rigging eyes - front and rear (pic. 4.25). Pull up the lifting device to remove the weight of the engine from the supports.
26. Turn out nuts of fastening of the right and left support of the engine to rubber blocks. Turn out bolts of fastening of basic arms to the block of cylinders and remove arms from the engine. On the N42 4-cylinder engine, we could not get to the right bracket mounting bolts. So we left the bracket on the motor and instead we detached the bracket from the rubber block. The left bracket was accessible and we removed it as above.
27. Pull the engine out of the engine compartment with a hoist. When performing this operation, the engine must be held and rotated as necessary so as not to damage the surrounding body parts, and not to hook anything important in the engine compartment.
28 Installing the engine is carried out in the reverse order of removal, taking into account the following notes.
- A) Tighten all fasteners to the required torque, if specified technical data.
- b) Route all wires in the same way. how they lay before disassembly.
- V) Install the accessory drive belt.
- G) Install the intake manifold as directed in chapter 4A.
- d) Install the radiator (see chapter 3).
- e) Install the gearbox (or transmission) and attach it to the engine (see chapter 7A or 7B).
- and) Finally, fill the cooling system and engine lubrication system (see chapter 1).
