You need to first drain the coolant, to lessen the mess of spilt coolant. Next you have to unbolt the coolant neck at the block to access the thermostat. After replacing, you have to refill/bleed the coolant system.
There is a bleed screw on the thermostat housing. Remove the screw with the engine loose. Ounc you have pure coolant and no air you can close off the bleed screw.

Did you bleed all air from the system? Did you check the operation of the water pump? Did you flush the system thoroughly? Did you accidentally install the thermostat upside down?
If there is not bleed valve for the coolant you will have to do it manually. Fill the radiator up and start the car. After it warms up the coolant level will drop, refill it.
To bleed the cooling system on a Mercedes-Benz S 500 after replacing the radiator and coolant, start by ensuring the heater is set to the maximum temperature and the fan is on low. Fill the coolant reservoir to the proper level, then start the engine and allow it to reach operating temperature while monitoring the coolant level. As the thermostat opens, air will escape, so periodically check and top off the coolant reservoir as necessary. Finally, once the engine cools, recheck the coolant level and add more if needed to ensure the system is fully bled.
On a 1993 Mercury Villager, the coolant bleed screw is typically located on the thermostat housing. It can often be found near the top of the engine, where the upper radiator hose connects to the thermostat. To properly bleed the coolant system, you may need to open this screw while the engine is running until coolant flows out, ensuring all air is removed from the system. Always refer to the vehicle's manual for specific instructions.
First check the water level. Low level will not get to the heater core. Change the thermostat. If you recently changed the thermostat, bleed the coolant system.
check or replace coolant thermostat or bleed the coolant system
I believe you want to drain the coolant, remove the top hose at the thermostat housing, remove the housing, replace the stat and gasket, reassemble fill with coolant and bleed the system.
The Citroën Saxo VTS typically has two bleed points for the coolant system. These are usually located at the highest points of the cooling system: one on the radiator and the other on the thermostat housing. To prevent air locks when refilling the coolant, it's essential to open these bleed screws after filling the system to allow trapped air to escape, ensuring proper circulation of the coolant.
