Power steering started to really whine and makes the revs up and down. Doing my head in as I put a used power steering pump last November. To try to save money first I looked up seafoam Trans fluid which helps power steering. Next day 80% of the whining gone!!!

Below is instructions. Worked for me anyway for now!!!!

Why did you not just change over the power steering fluid it will change around 90% using the method you used to put in the additive .

I did mine last autumn and used around two litres to get it back to pink.

Not sure how to change the whole fluid. How did you do this

The additive is supposed to clean steering rack also from what it says on google!!

The same way the transmission fluid is changed, take out a basting syringeful from the reservoir and replace with new syringeful.

When you start it will be black when you have put about 2 litres of new fluid in it will be nearly pink or red but it will be 85% new.

Much better than any additives.

Turkey baster a couple of pounds from the likes of Wilco’s.

On the subject of fluids there has apparently been a new check introduced on MOTs, the vehicle will now be failed on old discoloured brake fluid, this is normally a service item with recommended change periods
