Removal the engine (Skoda Octavia 5E)

Note: The engine is removed downwards together with the gearbox. After installing the engine, all cable ties removed or cut off during dismantling must be reinstalled in their original place. Leave the ignition key in the ignition to prevent the steering column from locking. Risk of injury due to fuel under high pressure. Before opening the high-pressure circuit of the injection system, the fuel pressure must be released to residual pressure.

Relieve fuel pressure in the high-pressure circuit. Open the "arrow" cap of the expansion tank.

Warning! Risk of burns from hot steam or hot coolant. When the engine is hot, the coolant in the cooling system is under pressure. To relieve the pressure, cover the expansion tank cap with a rag and carefully unscrew, gradually releasing the pressure.

Engine characteristics



Some points of removal and installation are described in 1.8 and 2.0 l engines.





Remove both front wheels. Remove the noise-insulating casing. Remove both front mudguards. Disconnect the electrical connector "2" on the coolant temperature sensor at the radiator outlet "G83" "3". Drain the coolant.

Caution! Install the used belt only in the previous direction of movement. Incorrect installation may result in belt destruction! Before removing the poly V-belt, mark its direction of movement with chalk or a felt-tip pen.
