Oil change Vauxhall Vectra 1999 - 2002

You will need to remove car's undertray / open the sump access cover

Here's the sump plug

Don't forget to place a suitably sized receiving tray beneath

Using a Torx-40 socket, carefully remove the sump plug and fully drain the oil. When the sump has emptied, wipe clean the sump plug area with a paper towel and refit a new sump plug and washer

Do not over tighten - replace the undertray
