Hello,
I have a 1999 Olds Alero 3.4 V6 and i have two questions. First off, my anti-lock light and trac off light come on only when i turn the wheels after I start it. And sometimes it does it when I put it into drive. Could this be a wheel hub baring needing replacement? And my cooling fans are not coming on. I have checked the fan motors they are good. Put in a new coolant tank with a new sensor, new thermostat, new temperature sensor, and Fan relay, what else could it be?
