On 3.0 litre V6 ST engines, carry out the following:
- Detach the top of the front anti-roll bar drop link from the right-hand suspension strut (use a 5 mm Allen key to stop the balljoint turning as the nut is undone).
- Remove the rear through-bolt from the engine rear roll restrictor – this will allow the engine to pivot forwards, creating more room at the rear. Securely wedge the engine forwards temporarily using a piece of wood, but make sure that no pipes or hoses are being strained.
- Remove the rear catalytic converter heat shield nut and two bolts. Slide the heat shield towards the transmission end of the engine, then down.
Remove the (main) auxiliary drivebelt.
To create more room for the alternator to be withdrawn, disconnect the outer end of the track rod end, as follows:
Loosen the nut securing the steering track rod end to the steering knuckle arm. Do not remove the nut at this stage as it will protect the balljoint threads. If necessary, use an Allen key to hold the balljoint shaft while loosening the nut
Slacken the nut while using an Allen key to hold the balljoint shaft...
Using a balljoint separator tool, release the balljoint from the steering arm
. If the balljoint is to be re-used, take care not to damage the dust cover when using the separator tool. Fully unscrew the nut and disconnect the track rod end from the arm. Discard the nut as a new one must be used on refitting.
...then use a balljoint separator tool to release the balljoint from the steering arm
On V6 engines, undo the alternator upper retaining bolt and unclip the wiring harness support bracket.
On petrol engines, remove the two lower mounting bolts and remove the alternator out through the right-hand wheel arch
On diesel engines the alternator mounting bolts and studs have already been removed during the drivebelt removal procedure.
Withdrawing the alternator through the right-hand front wheel arch
If required, undo the four retaining nuts and remove the plastic cover from the rear of the alternator.
If you are renewing the alternator, take the old one with you. Make sure that the new or rebuilt unit is identical to the old alternator. Look at the terminals – they should be the same in number, size and location as the terminals on the old alternator. Finally, look at the identification markings – they will be stamped in the housing, or printed on a tag or plaque affixed to the housing. Make sure that these numbers are the same on both alternators and the pulleys are identical.
Refitting is the reverse of the removal procedure. Tighten all nuts and bolts to the specified torque wrench settings.
