Removing the engines
The engine can be removed from the car separately or as part of the power unit. The total mass of both the engine and the power unit is very significant. It is recommended to remove the engine separately using a hoist and an assistant.

Removing the engine
1. Fix a cowl in vertical position or remove absolutely.
2. Disconnect the negative plug from the storage battery.
3. Drain the coolant.
4. Remove the radiator and cooling fan.
5. Remove the A/C compressor mount, move it aside and secure.
6. Disconnect the hoses from the power steering pump, close the channels with plugs.
7. Remove the air cleaner and disconnect the carburetor throttle control rods, as well as, where necessary, the elements of the injection system.
8. Mark and fix (write down) installation locations for all electrical connectors removed from the engine.
9. Disconnect the heater hoses, the remaining cooling system hoses and all vacuum hoses.
10. Disconnect the fuel hoses, as well as the pressure oil line.
11. Apply the parking brake, raise the front of the vehicle and place it on stands (supports).
12. On models equipped with automatic transmission (AKP), drain the liquid (oil) and disconnect the dipstick tube from the intake manifold. Disconnect the pipes from the oil cooler and remove the elements of their fastening on the power unit. Turn away bolts of a forward cover of transmission and fastenings of a leading disk to the hydrotransformer. Install two screws on the top of the cover.
13. Disconnect the wire «masses» and unscrew the nuts from the shock absorbers of the supports on the front cross member.
14. Remove the exhaust system (OG).
15. Remove the starter.
16. Install the stand under the gearbox. Loosen the rear cross member mounting bolts from the underbody and lower the assembly slightly. Remove all bolts securing the transmission to the engine with socket wrenches with extensions from the rear to gain access to the upper bolts. With all bolts removed, install the rear crossmember on the underbody.
17. Using an internal hex wrench, remove the lower mounting bolts. If the bolts stick, disconnect the engine mount from the body along with the shield.
18. Raise the front of the engine slightly with the hoist chains attached to the engine mounts.
19. Remove the engine from the supports and feed it forward (the front of the engine is raised) before disconnecting the primary (leading) gearbox shaft (or from a torque converter). On models with automatic transmission, make sure the oil pump is connected to the torque converter.
20. Remove the engine from the engine compartment, being careful not to touch the surrounding elements. Fix the gearbox on the body.
