The engine is usually removed together with the gearbox. A winch of the appropriate lifting capacity is required to remove the engine. Open the hood, unscrew the bolts holding it in place and remove the hood. Raise the front of the car using a garage lift or jack and place it on rigid supports (if the car is not installed on an inspection pit), secure the rear wheels with chocks. Remove the battery, keeping in mind that disconnecting the battery cancels automatic tuning of the radio to a specific station and erases the data in the memory of the engine fault diagnostic device, if such a device is installed. Remove the engine shield. Drain the coolant from the cooling system. To do this, remove the radiator and expansion tank caps, set the heater control lever to the "HOT" position and unscrew the drain plugs of the radiator and cylinder block. To avoid damaging the radiator, hold the plug nipple soldered into the radiator with a second wrench when unscrewing the plug. To avoid tearing off the edges of the plug, unscrew it with a socket or open-end wrench. Drain the oil from the engine sump and gearbox by unscrewing the corresponding drain plugs. After draining the oil, carefully wipe the plug magnets with a clean rag and reinstall the plugs. Disconnect the radiator hoses and remove the radiator and fan. Remove the inner joint ends of the axle shafts from the gearbox of front-wheel drive vehicles and tie up the axle shafts so that they do not interfere with the removal of the engine, having first wrapped the cuffs with wiping ends to protect them.
On models with power steering, remove the pump drive belt, unscrew the pump mounting hardware, remove the pump with the bracket and hang it in a convenient location without disconnecting the pump hoses.
On models with air conditioning, remove the A/C compressor drive V-belt, disconnect the compressor and hang it in a convenient location without disconnecting the hoses.
On models with a hydraulic clutch drive, remove the hydraulic cylinder with the hose and also secure it in a convenient place. With the hydraulic cylinder removed, do not press the clutch pedal. On models with a cable clutch drive, disconnect the cable. Disconnect the transmission control rods. Disconnect the muffler inlet pipe from the exhaust manifold.

Disconnect the electrical wiring that prevents the engine from being removed, after marking their installation locations (for example, by attaching a piece of paper with the appropriate inscription using adhesive tape). Disconnect the hoses and pipes from the engine that prevent the engine from being removed, also having previously marked their installation locations. Hook the hooks of the hoist onto the engine's cargo eyes, tighten the chains of the hoist enough to relieve the engine mounts. Unscrew the engine mount mounting bolts and remove them. Carefully remove the power unit from the engine compartment, gradually lifting it with the hoist.
Install the engine in the reverse order. Before installation, be sure to check the condition of the rubber cushions. If necessary, replace damaged or worn cushions. To ensure equal elasticity of the engine mount elements, it is recommended to replace all rubber cushions at the same time.
