The steps below are shortened from the Vauxhall TIS pages for the Speedster. The VX220 shares the same engines and most of the car, but check anything unusual against your own car. The TIS pictures and the full wording aren't reproduced, so use the workshop manual if you are doing the job. We haven't seen owners' accounts of this job, so there are no owner tips here.
