It may appear to be coming from the radiator. A leak is a leak, and it can cause serious prolems inside your engine. It could be a house, a gasket, the water pump, or you may have missed a radiator leak. Over heating can cause this too, and that presents other problems. Lastly, your radiator cap may be failing. That's a cheap first step. Don't let this go for long, keep fluid in your system at all times.
It probably has a leak. Here's something to check - the radiator has a tube coming out to the reservoir, so when it gets hot and expands the coolant goes into the reservoir and should go back into the radiator when it cools, but if your reservoir has a crack and the coolant leaks out, well it's gone and can't go back into the radiator - this would cause a lot of loss of coolant.
Coolant goes in the radiator or you can also fill the radiator resevoir.

Not much info to go on. First thing to do is pull over and check the coolant level in the coolant reservoir. If the reservoir is empty look for obvious leaks and repair as necessary. Never open radiator cap when engine is hot. If you don't see any obvious leaks have vehicle towed to a garage for diagnoses.
There is a low level sensor in the side of the radiator. They do go bad.
NO just Coolant
Get something for the coolant to go into like a bucket. Remove the lower radiator hose from the radiator and also remove the radiator cap to help and drain into bucket.
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.
Next step after this would be to replace the radiator pressure cap, check ALL hoses for deterioration and leaks, check the coolant resevior bottle for leaks, and all connections to it. Check the drain plug and make sure it's snug in the bottom of radiator. Also, you may need a new water pump. Good Luck! I agree about the water pump, even if it seems as if it is working it will give poor circulation and cause overheating when pressurized until the bearings finally go out completely. but check the pressure cap first it is the most obvious and cheapest option, if it is bad when the system builds pressure and heat it will allow coolant to pass freely into the reservoir, but not draw it back in.
any radiator fixit that you buy in a store is a temporary fix usually makes the problem worse you can take radiator to a radiator shop where they can tell you if it is repairable or u need a new one now here is also a fix that will work but try not to laugh go into your kitchen and get the ground black pepper . that's right the stuff you put on your food pour this into radiator top off radiator and run engine this will stop leaks without gooing up anything else i know you are laughing but it does work when time comes to change coolant, this will just run out when u dump the old coolant
In the radiator and the overflow bottle.
Low coolant? Cooling fan not working? Radiator restricted or plugged? Water pump not circulating coolant? Defective radiator cap? Low coolant? Cooling fan not working? Radiator restricted or plugged? Water pump not circulating coolant? Defective radiator cap?
