Radiator only coolant tube got disconnected so the coolant leaks out

Get the coolant pressure tested, its definitely leaking coolant. You will need to get the coolant running line.

Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.

please let me know if i can assist you in any further problems you may encounter with your vehicle.
please do not forget to rate and comment about your experience with fixya today.

sounds like hoses going to heater core but they are rubber usually. But it could be the hoses for the degs bottle mounted on the passenger side inner fender.

Coolant Recovery System NOTE: When the water thermostat (8575) is closed, coolant flows through the degas tube and hose assembly from the lower intake manifold to the radiator coolant recovery reservoir (8A080) .

Trapped air in the cooling system must be removed. A pressurized radiant coolant recovery reservoir system is used which continuously separates the air from the cooling system.

• When the water thermostat is open, coolant flows through both the small hose from the top of the radiator outlet tank and the degas tube and hose assembly from the engine to the radiator coolant recovery reservoir.
• The radiator coolant recovery reservoir separates any trapped air from the coolant and replenishes the system through its radiator coolant recovery hose.
• The radiator coolant recovery reservoir serves as the location for:
  • service fill.
  • coolant expansion during warm-up.
  • system pressurization from the pressure relief cap.
  • air separation during operation.
• The radiator coolant recovery reservoir is designed to have approximately 0.5-1 liter (0.53-1.06 quarts) of air when cold to allow for coolant expansion
