Power steering.. as if you even need it on such a small car!!
You will really only notice a difference at very slow speeds.. ie. >5mph. If its pretty heavy (takes alot of effort) to steer at these speeds, your PAS is being affected. If not it should be ok.. Im not an expert, but Check for any holes/ wear and signs of damage elsewhere in the engine bay. If it looks solid enough & isnt playin up.. No worries really!
