Remove the fuel rail mounting screws.

Spray universal oil or similar around the injector connectors on the intake manifold.

Gently work the fuel rail and injectors loose.

Carefully put the fuel rail to one side.

Removing ignition coils

Mark up the ignition coils so that the original positions can be established.

Remove the mounting screws for the ignition coils and the screws at the two ground terminals.

Disconnect the connector for the variable valve timing solenoid.

Lift up and place the ignition coils and wiring to one side.

2. the by-pass valve vacuum hose
3. the upper row of screws holding the intake manifold to the cylinder head. Slacken off the lower screws
4. the pipe screw for the crankcase ventilation from the underside of the intake manifold.

Disconnect the connector for the electronic throttle module.

Lift up and remove the intake manifold.

Note. Make sure that the fuel delivery pipe is not damaged.

Scheme 92

Disconnect the connectors for the ABS sensor and level sensor in the expansion tank.

Lift up the expansion tank and servo oil reservoir. Place them on top of the engine.

Note. Make sure that power steering fluid does not leak from the breather hole in the filler cap.

Take off the auxiliaries belt.

Remove

1. the front timing cover
2. the hose for the water-heated crankcase ventilation from the thermostat housing.

Separate the connector for the engine coolant temperature (ECT) sensor.

Draining coolant

Raise the car.

Remove the splash guard under the engine.

Open the engine nipple.

Drain the coolant into a container.

Close the nipple.

Drain the coolant and loosen the front exhaust pipe

1. Remove the cable from the battery negative terminal. First read «Battery, disconnecting»(ref-438278-S34403393232011120100000) .
2. Remove the cap on the expansion tank.
3. Remove the splash guard under the engine.
4. Place a container under the engine's drain valve and drain the coolant.
5. Move the container to the radiator's drain valve and drain any remaining coolant.
6. Close the nipples.
7. Remove the nuts for the manifold/front exhaust pipe.

Drain the fuel line

The illustration does not match completely since the power steering fluid tank now has another placement.

1. Depressurize the fuel system acc. to «Fuel system pressure release»(ref-403959-S38366318392011061000000) .
2. Disconnect the fuel line quick-release connector at the engine NOTE: Protect the openings against impurities in a suitable way. Make sure that all cleanliness conditions for working with the fuel injection system are followed.
3. Put the line to the side.
4. Detach the EVAP line at the quick-release connector.

Drain the coolant and detach the front exhaust pipe

Detach the negative battery cable.
