Engine subframe — removal and installation (Opel Omega B2)

Removal

1. Apply the handbrake, then jack up the front of the car and support it securely on axle stands. Loosen the fasteners and remove the lower engine compartment shield.

2. On models with Xenon headlights, disconnect the wiring from the front longitudinal vehicle roll sensor (see the relevant section).

3. Unscrew the bolts of the ball joints of the lower arms from the base of the steering knuckles (see Chapter 4).

4. Disconnect the vertical rods from the ends of the anti-roll bar (see Chapter 7).

5. Unscrew the nuts securing the engine mounts to the subframe and engine brackets (see the relevant section). Where available, remove the vibration damper strut bolts from the frame.

6. Bring a winch to the engine compartment. Attach slings to the engine mounting eyes and lift the winch to support the engine weight.

7. Apply alignment marks to the subframe and underbody.

8. Support the frame with a jack, placing a piece of board between them.

9. Mark the six subframe mounting bolts with respect to their positions (they have different lengths and diameters). Gradually loosen and remove the bolts, then lower the engine subframe on the jack and remove it from under the car.
