i assume you mean "heater core". this is a really small radiator usually located behind the dashboard of your car. a fan blows across it when you turn the heat on. this radiator can leak eventually, just like the regular radiator is prone to doing with age.
the difference is that to fix the heater core you have to tear the dash out of your car. i would just take it to a mechanic to fix, or buy the bypass kit at any auto parts store and cap it off (you won't have heat if you bypass it)
hope this helps!

Can a planetary core be cold?
Certainly, a planetary core can be cold. The heat of our own planetary core is the result of radioactive decay of various elements in the core and mantle, but eventually that heat source will be used up, and the residual heat will gradually leak away into space. There could be other planets which never had much or any abundance radioactive content in the first place.
Your ford windstar has a steam that comes into the vents when the car is warmed up that covers the entire inside of window It also has a antifreeze smell when the AC or heat is on any thoughts?

Why do you get smoke coming through your vents on my 1999 dodge Dakota when you turn the heat on?
Sorry bad news Your heater core has a leak
What can cause white smoke coming out of vents?
That is probably antifreeze steam. Your heater core is a small radiator used to heat your car. The engine heats the antifreeze and circulates it through the heater core. Your blower blows heat through the core (radiator) into the car, and warms you. If the core gets a small leak, it will put out steam.
Why would a car leak antifreeze only when the heat is on inside the car but doesn't leak when the heat isn't on?
The heater in a car is a little radiator under the dashboard. It's called the heater core. There's a valve in the water system that sends hot coolant into the heater core when you turn on the heat, and keeps the coolant in the engine when you don't want heat. If the car is leaking antifreeze when the heat is on but not when it's off, something in the heater system has a hole in it. Because there's always coolant in the heater core and the hoses that feed it, my first thought is the valve itself is bad.
