Engine coolant expands when heated. Heated coolant needs a reservoir to come and go as needed.

Both. The reservoir is the overflow. But in the event your radiator is low, your reservoir will back it up.

How does an automotive radiator reservoir work?

A hot radiator releases excess coolant through the spring-loaded cap in to the reservoir, and when cooled the partial vacuum created by cooled radiator pulls it back in. A reservoir should be only about 1/4 full cold on a system that uses a radiator cap, some cars have a pressurized cap on reservoir and no cap on radiator

When 2001 Ford Taurus runs hot in idle do you need to add water to radiator?

Not necessarily! Let it cool down then check the radiator water level and the water overflow reservoir tank. In a properly operating system the reservoir adds water as needed to the radiator when it cools down after you quit driving. #1. The radiator should be full of water and the reservoir tank should be 3/4 full of water. #2. At a certain temperature or with the "AC on" the radiator fan(s) should be sucking air over the radiator and cooling coils. So! Fill the radiator and the reservoir and when it overheats in idle see if the fans behind the radiator are operating.

If the reservoir has a hose that travels to the top of the radiator, then it is filled with engine coolant. If the hose is not connected to the radiator, then it is most likely a windshield washer bottle.
