no antifreese
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.
Coolant is added to the overflow bottle instead of the radiator. The overflow bottle will allow fluid to fill over into the radiator.
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.
On the coolant overflow bottle
In the radiator and the overflow bottle.
With the engine cold, put it in the radiator just to be sure there is no air gap. Run it for a short time until it gets warm and coolant begins to circulate. Then install the radiator cap and put coolant in the overflow to the coolant level line.
through the overflow bottle
you add coolant to e150 thru the radiator overflow bottle
by adding more gas I'm weak on Fords, but radiators are filled either at the radiator or the overflow bottle. The overflow bottle will be marked coolant only.
Radiator Coolant level in the overflow bottle is low. Fill the overflow bottle with coolant. If you have coolant in the bottle, the switch is stuck. Remove the whole overflow bottle and clean with some CLR (calcium, lime, rust) remover.
In systems that do not have a radiator cap, the coolant is drained by the radiator drain plug. It is filled by adding coolant to the system through the overflow bottle.
Remove the radiator cap when the engine is cool and add the coolant into the radiator or you can add to the coolant overflow bottle. DON'T remove the radiator cap when the engine is hot!!!
