Instantly. If someone is telling you otherwise, they're blowing smoke.

Purg The Air Out of the Cooling system
you have an airlock
If it is leaking coolant. And you changed the thermostat. I would then move to this section. Flush the radiator and the heater core. This can be done at a certified shop with a reliable mechanic.
the ac stoped working and so did the heat . I changed the thermostat added freant
You might have bad actuator that opens and closes airways.
have you changed the battery in the thermostat?
that's the complete oposite to mine! mine just keeps blowing hot air out! changed the thermostat and still nothing changed, in the end i just unhooked so it constantly blows cool air gonna be a problem in the summer!
You may have the thermostat in backwards. The spring side of the thermostat faces into the engine.
No
Have you replaced the thermostat?
