When bleeding the clutch on a Vauxhall Vectra 1.8 2002 the fluid that comes out looks cloudy with sort of air bubbles in it should the fluid be drained and all new added or is this something else causing the cloudy fluid even if I put new in. Or if I add new to the existing fluid by bleeding the system will it force out the bad.
Cloudy means air is present in the fluid and you need to keep bleeding till new fluids comes out with no bubbles. When bleeding, it is always good to get rid of any old fluid in system, just keep bleeding and topping up until the desired result is achieved.
If problem persists, it means the master cylinder is failing.
