How often should power steering fluid be changed? My late model Kenworth has 6 month interval.

Never. Wait until the pump's fried and the box is leaking like a sieve. You can put new fluid in after you change out $500 worth of parts. :hehe:

But seriously - do you know when it was last changed? If not, you might want to go ahead and do that anyway, just for grins 'n giggles.

If you change it once a year you will be way ahead of 90% of everybody else. ATF+4 is what I recomend.
