The radiator may be pushing coolant back into the overflow due to a few potential issues, such as a malfunctioning radiator cap that fails to maintain proper pressure, allowing coolant to escape. Additionally, a clogged radiator or a failing water pump can disrupt coolant flow, leading to overheating and fluctuations in temperature readings. Air trapped in the cooling system can also cause irregular coolant circulation, exacerbating temperature fluctuations. Regular maintenance can help prevent these issues and ensure optimal cooling system performance.
In all probability you either have a bad radiator cap or an air lock.
Bad radiator fluid.
Filling the overflow to the correct level will suffice as the radiator will draw out what it needs.
the overflow res. cap is the radiator cap on the 97 cavalier
The hose that goes from the overflow to the bottom of the radiator on a 2002 Windstar is the bypass hose. It allows coolant from the overflow to return to the radiator as it cools.

No.
no antifreese
No
Coolant is added to the overflow bottle instead of the radiator. The overflow bottle will allow fluid to fill over into the radiator.
In a radiator, the fluids get really hot, when things get hot they expand and then they have to go somewhere, the fluid goes into an overflow.
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.
