your Toyota should have an overflow bottle to retain the antifreeze during normal operations. Unless it is overfull, I would be looking for a leak.
yes

Yes. There should always be some coolant in the overflow tank. Its level should rise when the engine warms up, and it should go back down when the engine cools.
It should be located in the coolant overflow resivoir.
Coolant for the 98 Deville is added into the coolant overflow bottle. The side of the bottle should have low and high coolant markings.
Check your coolant level in the radiator as well as the overflow reservoir. Believe it or not, I had the same problem yesterday. This should fix your problem.
Full to the level of the lower of the two lines that are molded into the overflow tank.
Look on the side of the coolant overflow bottle. There should be a low mark for the coolant for a cool engine, and one for a hot engine.
To check the coolant level of a vehicle first see look for the overflow reservoir. There should be a coolant dipstick with a level gauge on it. Remove it from the reservoir to see the coolant level.
It should be filled to the "Full" mark on the side of the bottle.
It should be up to the cold mark ( at least that's the way it is on my vehicle )
The coolant for a BMW x5 is placed into the coolant overflow tank on the left side of the engine compartment. It should be filled to the full mark when the engine is at operating temperature.
