Coolant only moves from the overflow tank/container to the radiator when the engine is cooling. It flows the other way (into the tank) as the engine heats up and coolant expands.
If coolant isn't moving into the radiator when the engine is cooling down there could be a couple of reasons.
1. The engine really never got warm enough to begin pushing coolant to the tank and the radiator is already full.
2. The radiator cap is faulty and should be changed.
3. If the coolant hasn't been changed for many years it's possible (though unlikely the hose linking the tank and radiator is plugged.
Thoughts: Be sure you're adding a 50/50 mix of coolant and distilled water to the overflow tank, not just water. Note the coolant level in the tank with the engine cold then go for a drive. Check the level again. It should be a little higher. Let the engine cool and the level should be back to the original point. If that's the case you're good to go. If coolant is pushed into the overflow but the level doesn't drop again blame the radiator cap and get a new one.

What else can I help you with?
Why is water put in a radiator?
Water is put in a radiator because it is used to transfer heat from the engine to the outside environment through the process of convection. The water absorbs heat from the engine and then circulates through the radiator to release it, helping to cool the engine and prevent it from overheating.
Why is your radiator leaking water?
A radiator can leak water due to a cracked or corroded radiator, loose connections, a faulty radiator cap, or overheating causing pressure buildup. It is important to identify the cause of the leak and address it promptly to avoid damaging the engine or causing overheating.
What is a example of heat transfer by convection?
An example of heat transfer by convection is when hot air rises from a radiator and circulates throughout a room, warming the air in contact with it. This causes a continuous flow of warm air, distributing heat around the room.
Can you put straight water into cooling system next to radiator?
It is not recommended to use pure water in a car's cooling system next to the radiator. Coolant or a mix of water and coolant is usually used to prevent freezing and protect against corrosion. Pure water has a lower boiling point and can lead to overheating and damage to the engine.
When water changes into ice it expands or contracts?
Water expands when it freezes into ice because the molecules rearrange themselves into a more structured hexagonal arrangement, which takes up more space per molecule compared to the random arrangement of liquid water molecules.
Where do you put radiator sealant in a 2003 Dodge Intrepid or where is the radiator cap?
the water overflow tank
How do you add water to the radiator of 2003 Chevy Tahoe?
You put it in the overflow jug.
Where do you put water in radiator on a ford E 150?
you add coolant to e150 thru the radiator overflow bottle
Where do you put and fill water in BMW car engine?
At the radiator or overflow tank. Do not add water, add coolant.
Where do you put water in the radiator for 2000 grandam?
the overflow reservoir, it should have marks for full cold and hot
Where is the antifreeze tank in a 1995 Honda Accord or do you just put it in the radiator?
Put it in the radiator but also make sure the overflow tank is full. Follow the overflow tube from the radiator and you will find the tank.
If there is not a radiator cap on a 1991 Jeep Cherokee Laredo where do you put the water?
in your coolent overflow tank then squeeze the upper radiator house to pump it through the rest of the radiator and to the engine.
How do you fill radiator fluid for Mazda MPV?
you have to put the radiator fluid in the overflow. This is the only way.
After replacing radiator hose do you put coolant in the radiator and the overflow bottle or just the 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.
Where do you put water?
If you are referring to a vehicle you put a 50/50 mix of distilled water and coolant in the radiator and overflow resivoir. You also put distilled water in the battery if it is not sealed. Also the windshield washer resivoir holds washer fluid which is part water.
Why did the radiator overflow bottle 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.
Where is the the place to put water into the radiator of a 2001 Saturn L300 you cant find the radiator?
there should be an overflow container on or near one of the wheel wells. that is where to add anti freeze to most newer model vehicles
