Hi Guys,

I am gradually working through a programme of preventative maintainance and wish to flush and refill my power steering system.

My Volvo handbook gives the fluid type as "Pentosin CHF 11 S". Haynes recommends "Dexron type ATF"

So..... my question is will a 'normal' Dexron 3 ATF of any brand be OK?

If so, then I guess a fully synthetic type such as Amsoil or Mobile ATF would be good as an upgrade to the recommended?

Is this correct?

Also, I believe a magnet suspended within the reservoir would be benficial in collecting ferrous particles. I had thought of epoxying a large 'penny washer' on the outside of the reservoir just under the inlet pipe and below the normal fluid level and then placing one of these small very powerful magnets (about the size of a £1 piece) within the reservoir at the same level as the washer. I guess there might be an outside chance of the magnet being displaced within the reservoir and then going down the feed pipe to the pump!!! (I doubt that this is really possible since the magnets are incredibly strong).

Does this sound like a reasonable (or daft!) idea?

Cheers, Terry
