We remove the car engine by lowering it down together with the gearbox from the engine compartment
To complete the task, you will need a lift to raise the front of the car higher.
If we are doing work in a garage, in the absence of a lift, we need a jack and strong high supports to install a raised front part of the car on them, which will make it possible to remove the engine from under it.
Tools required: wrenches for 10, 13, 16, 18, sockets for 16, 18, a set of screwdrivers, a container for coolant, hydraulic support.
We release the fuel pressure in the power system, as described in the article - "Replacing the additional Renault Duster fuel filter"

Setting aside the wiring harness
Install the supports under the power unit
We unscrew the five bolts of the right engine mount
We unscrew the three bolts securing the support to the gearbox
We check once again that all wires and hoses are disconnected from the engine.
Lower the engine on its stands, keeping it from falling.
If it is not possible to lower the engine on supports, hang the front part of the car (raise the car on a lift) to a height sufficient to remove the power unit from under the car, and place reliable supports under the body.
Install the engine, as well as 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.
Fill in the oil
Refill coolant.
Start the engine and check for fuel, oil and coolant leaks.
Check the oil pressure.
Listen to the engine, it should run smoothly, without extraneous noise and knocks.
