Power steering, hissing 2003 ZTS
I know this is a fairly common problem category so maybe you guys (and ladies) can make a suggestion for trouble shooting.
The problem, hissing while turning left after warm up. Doesn't take much of a turn either, bout 25 degree turn on the wheel?
I had this problem at about 26k and had it looked at by the dealership. They didn't do much but the sound went away. They purged they system and topped it off.
The actual print up is a bit iffy but here it transcribed, word for word.
Hissing noise from steering when turning left MT=extensive R/T for diag. Purge P/S system long test drive to verify cust concern found that after vehicle warmed up & while turning to the left found that there was a hissing noise at near left lock on power steering inspect all line rack vehicle test while not under load found noise still there found possible air in power steering syst. Test by turning lock to lock & watching fluid found slight discolor from poss air vacuum pump to 15 psi & turning wheel from time to time to evac air from syst added fluid retest found ok at this time.
What would you do? Obviously this has to be fixed and the dealership didn't fix it before. By the way, the fluid is at the right level but it is pretty dark, say like chocolate syrup mixed with coffee.
Did I leave anything out?
