The engine probably has a bad head gasket or a cracked head.
If you mean the plastic overflow tank, replace it. If you mean the plastic tanks on either side of the radiator core, replace the radiator.
Might mean you have internal engine damage like a blown head gasket. You need to get this professionally checked.
thermostat or blown head gasket....
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
yes
No.
Coolant is added to the overflow bottle instead of the radiator. The overflow bottle will allow fluid to fill over into the radiator.
