Remove the engine assembly with the gearbox, lowering it down from the engine compartment

This requires a lift. to raise the front of the car higher.

In a garage setting where a lift is not available, a jack is required, as well as supports that are strong and high enough to place the raised front of the car on them, which will make it possible to remove the engine from under it, lowered to the garage floor.

For convenience, remove the hood.

Depressurize the supply system (see Reducing the pressure in the supply system).

Remove the air filter (see Removing and installing the air filter).

Disconnect the wires from the battery and remove it from the vehicle.

Remove the engine from under the car,

Install the engine and all removed components and parts in the reverse order of removal, taking into account the following:

  • - before installing the power unit, clean the threaded holes for fastening its supports with a tap;
  • - be sure to replace the exhaust pipe gasket with a new one;
  • - when connecting wires and pipelines, carefully monitor the correct location of them in the engine compartment, avoiding contact with heating and moving elements of the power unit.

After installing the motor, do the following:

Refill with oil (see "Changing the engine oil and oil filter")

Fill the gearbox with oil.

Refill with coolant (see "Changing the coolant").

Adjust accessory drive belt tension

Adjust the throttle actuator (see Adjusting the Throttle Cable).

Start the engine and check for fuel, oil and coolant leaks.
