I just bought a 2000 S70 GLT. On the back cover of the manual there is an under-the-hood diagram that points out locations for the Washer Fluid, Coolant, Power Steering, Oil, and Brake Fluid reservoirs. Additionally, on one of the inner pages, there is a similar diagram that also shows the Automatic Transmission fluid dipstick. Where is the reservoir for the Automatic Transmission fluid? I know that the Power Steering fluid for this car is ATF. Do the Power Steering and Automatic Transmission share the same reservoir (the Power Steering reservoir)? Why is the AT dipstick needed if the Power Steering Fluid reservoir has its own dipstick?

The manual indicated that the Power Steering Fluid is not required to be changed. Can this be true?! If not, when should this be flushed/changed? Is there one particular over the counter brand of ATF that should be used (even if only to top off this reservoir)? If I decide to have this fluid flushed/changed at a garage, how much should I expect to pay?

When the Coolant is flushed/changed, the manual states that only 'Volvo Genuine Coolant/Antifreeze' be used. How does Volvo's antifreeze differ from Prestone(mixed 50%/50% as directed on the back page of the manual)?

Thanks for your help.
