Antifreeze should show up to the level line when cold normal but may raise some when hot and fall below some when cold. This is due to expansion and contracting from engine being hot or cold. A slight fall below this line can not mean much it can also evaporate some. A small leak can loose some but if you are putting fluid in everyday or two then you probably have a leak someplace.
Always check and fill from the rad neck. If your car is equipped with a reservoir tank it will be attached by a hose to the neck of the rad. Follow it to find it.I hope this helps you. Mark
When running the air conditioner, there might be a small leak of fluid on the 2000 Alero after it is parked. This is normal as it is only the overflow valve being released. Always check the antifreeze level before operating the vehicle in the summer to prevent low antifreeze warnings.
always use manufacture specified fluids for your vehicle, it will say in the owners manual and in the engine compartment somewhere close to the overflow resivoir
We always renew the antifreeze in our car before winter.
perform a compression test to check for leaking head gasket- you may have caught this before any major damage occurs,

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.
Always use antifreeze. Water does not have any water pump lubricants or anti corrosion properties, antifreeze coolant does.
You should always use a 50/50 mix of antifreeze and water.
Look carefully around your engine bay and identify parts. The windshield washer, oil, trans, and coolant lids are almost always marked on top. You put the antifreeze in the radiator or coolant overflow bottle. You often have to drain or remove some water first. - Better yet, get a manual for your car so you can understand it and do simple maintenance.
Yes unless you are out in space.
No. From some parts of the world it is NEVER visible.
