Yes, adding coolant because of boiling overflow. At last service they claim to have flushed the radiator. Have owned the truck for +- 5 years, second hand, and have never replaced thermostat. When truck boils I open radiator cap to refill and find small pieces of hard plastic inside. Truck is now on 250000 km. Have just started engine cold and bottom radiator hose is not collapsing. Seems to only happen when engine is overheating. Glen
