When starting the car the hose from the thermostat is very soft and nothing coming from it as well. Is this normal? If not, what could be wrong?

Hi:
Yes and no. When the cooling system cools off, the pressure is released and the hose will become soft. Never open a radiator cap when the hoses are hot. However, there should be coolant in it. Make sure the radiator and overflow is full.

A soft thermostat hose after the cooling system cools is normal because system pressure drops. Confirm coolant is still present, keep the radiator and overflow full, and never open the radiator cap while the hoses are hot.
