Normal antifreeze levels in the coolant recovery tank are around the half way point. This is usually marked with an Full or F on the side.
Coolant will expand as it heats - that's the purpose of the coolant recovery tank - to take excess when vehicle is hot and return it to the radiator when vehicle cools
The coolant is being circulated by water pump. That is normal operation. Ensure coolant is at proper level (and bled if required).

Coolant Recovery Reservoir. There is no sensor in the coolant recovery tank on a 1998 Buick Regal.
because your coolant level is too low. put some antifreeze in it......
Coolant is fluid that flows through a device in a vehicle to prevent overheating, The coolant level sensor is located on the bottom side of the coolant recovery tank.
probably the coolant level sensor... Does the temprature gauge go up to hot then down to normal?
If your coolant level is down ( because of a leak somewhere ) there won't be any flow of coolant through your heater core if the coolant level drops too low and you won't get any heat Find where the coolant leak is , repair it , and refill the coolant system with 50/50 mix of antifreeze and preferably distilled water ( in colder climates you can use up to 60 % antifreeze , but don't exceed that )
