coolant level warning

[Karl]

I occasionally get a low coolant warning message in the instrument cluster, but when I check the level, it's OK. Any likely suspects in the wiring? Or does the little float switch give out on these cars?

A small stream of coolant should flow near the fill cap. If this small stream of coolant doesn't flow, then check the return hose & give it a blast with compressed air or snake it with weed eater line to make sure it's not clogged.
