What does power assisted steering (PAS) fluid do?
The power assisted steering (PAS) fluid is the hydraulic liquid that is used in vehicles with a power assisted steering pump which is forced under pressure into the steering rack system to reduce the effort needed to turn the steering wheel.
What does a power steering fluid change involve?
Changing power assisted steering (PAS) fluid is a routine repair for all mechanics and can be done both kerbside as well as in the workshop, providing it is safe to do so.
Whilst there are variations between manufacturers, the basics are pretty similar.
The mechanic will;
- Check the condition of the fluid and proceed if deemed to require changing
- Undo the system bleed valve and drain the existing fluid out
- Depending on how tainted the fluid was, either refill it and bleed it or flush it through before refilling it and bleeding it.
- Test the vehicle’s steering once again

In addition to this, the fluid can be checked physically by removing the fluid reservoir cap (it usually has a picture of a steering wheel on it). If the fluid is clear, or bright in colour (usually green or red) then it's likely to be OK, If it is brown to black, then it has likely been contaminated.
