Bad radiator fluid.

coolant overflow/reservoir tank
The radiator cap could be the cause of coolant reservoir overflow or backup. Have the cap checked to see if it is bad.
If you mean the cap for a car radiator the water will heat up and overflow. The radiator/cooling system requires a pressure of usually around 16 lbs which is what the radiator cap provides in stopping water from overflowing.
Coolant for a 2006 VW Bettle is put into the coolant overflow tank. As it is needed, the radiator will automatically pull in additional coolant.
The overflow bottle may overflow if: 1. The car is overheating - this means after the coolant in the radiator gets heated up and expands it flows to the reserve bottle but the radiator doesn't cool down to suck back the coolant from the overflow bottle, but just keeps on sending coolant to the bottle. 2. You may have put excess coolant in the bottle - hence heated coolant from the radiator didn't get enough space.
no antifreese
Coolant is added to the overflow bottle instead of the radiator. The overflow bottle will allow fluid to fill over into the radiator.
It is on the overflow bottle.
Engine is overheating.
Depends what type of car, but generally it's near the radiator.
Filling the overflow to the correct level will suffice as the radiator will draw out what it needs.
On the coolant overflow bottle
The radiator cap may be at fault.
In the radiator and the overflow bottle.
On the plastic overflow bottle
An overflow tank is a bottle that holds coolant that expands and leaves the radiator under driving conditions. The Coolant will go back into the radiator as needed.
