I'm just curious about the power steering hoses that has a very small leak. Every time I looked under the hood, I don't see it at all. So my question is what can it possibly be. And I was told by a mechanic not get a power steering flush. And if it is the hose, what's the name? Thank you.

Have you had any power steering problems? Do you have reason to distrust the mechanic who gave you this diagnoses? If so, take it to another mechanic to get a second opinion.

As for the hoses, there'll be two hoses in you power steering system. One is the feed line (High pressure) to your rack and pinion, the other is a return line (Low pressure) back to the pump.

You could have a tear/puncture in the rubber, or a leak in the terminal (what connects it to the pump and rack). And finally, the pump and rack & pinion themselves can have a leak in one of their many seals.

Usually, a leak is pretty easy to find, so long as you get under the hood or the vehicle to have a look.

As for "Power steering flush", the only reason to do that is if there's debris in the system. Such as a pump has failed or the racks gears have stripped. Then that will usually place small metal particles in the fluid. And when you're replacing an old rack or pump with a new one, you don't want it to circulate that old contaminated fluid or the new ones will fail also. So then it's necessary to flush the fluid.
