    Does this mean it is normal for coolant level in the reservoir tank to drop when the engine is hot and come back up when it cools?

    You've got that mixed up, when coolant heats up it expands and builds pressure, when pressure exceeds a certain rating on the radiator cap and radiator is completely full, excess coolant due to expansion will flow into the "expansion" tank through a bleed hose (or reservoir, or overflow, different names, same thing) when engine cools down coolant also cools down and contracts, creating a small vacuum and drains back into the radiator.

    Yep, other way around. Coolant level will rise when engine is hot, level will drop when engine cold
