Hello all. I have a 2000 Ford Focus 2.0L Zetec that takes Mercon V Transmission Fluid for the Power Steering unit. Now I bought the car used so I am trying to flush all the fluids out and replace with new synthetic. I have already done my motor and trans. Now my question is would I be able to use a trans flush product to clean my power steering unit since it already has trans fluid in there in the first place? And what type of flush would I use? I know some people will recommend AutoRX but I was thinking of something off the store shelved.....but something good! Any suggestions will help. Thanks!
