ABS light & low coolant light on

On my 1993 buick park ave ultra my ABS & low coolant light stay on but there seems to be nothing wrong with either. Is there a sensor that might be bad?

If the ABS light is on, there is a problem somewhere in the system. You will need to take it in to a mechanic to diagnose the problem (unless you happen to have a GM Tech1 scanner handy).

The low coolant level problem is probably a bad sensor. The sensor is located on the back of the radiator, just below the upper radiator hose. It will have a wire that plugs into it. That's an easy fix.
