It was leaking fluid to the point it was needing to be filled everyday...replaced hose and radiator. Fixed it.
Driving, stopped at light, when accelerated and turning it sounded light a reviving engine (really lound) and than we could barely turn the wheel - fluid all over under hood - we immediately took home and parked - will have to tow to repair
