In all probability you either have a bad radiator cap or an air lock.
Bad radiator fluid.
Potenially a bad temperature sensor or bad contact on the wire connector. Test for set voltage resistance according to temperature.
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.
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.
