Automatic Transmission fluid
The power steering fluid reservoir is up on the passenger side wheel well in the engine bay. Looks like a short fat silver coke can with hoses coming out of it. On a side note, the 300zx twin turbo uses ATF (automatic transmission fluid) not power steering fluid. usually a green casing with black top. the following link is NOT a 300zx, but the reservoir is about the same. http://www.sillbeer.com/images/engine/power-steering-reservoir.jpg

in the power steering pump, on drivers side out near front of motor.
the power steering reservoir would be to the front left (green casing with black top) this would be you facing the car from under the hood. the hose below it should route you to the power steering pump. it is also recommended to use ATF (Automatic Transmission Fluid) and NOT power steering fluid in the reservoir (from personal and professional experience, it leaks far less)this is what it would look like... but this is NOT the same car, but the part in question looks identical)
It will hold between two and three quarts

no, but it will lose alot of power
Make sure pump has enough fluid. Then in a slow steady fashion turn the steering wheel left to right going from steering stop to steering stop 5 or 6 times
Chevy 6.5 turbo diesel more than likely has a hydroboost brake system. It means instead of having a vacuum type brake booster it uses hydraulic pressure supplied by the power steering pump to aid in braking. I would think it is more than likely the power steering pump or a power steering fluid leak or a slipping serpentine belt.
