What does it mean if first you had no heat and now you notice no antifreeze in your overflow tank?
Coolant leak?
Check to see if coolant is getting mixed with engine oil
Run engine to normal operating temperature and remove oil dipstick, let a drop fall on hot part of engine - oil will smoke coolant will sizzle.
If coolant is mixed with oil could be a bad head gasket.
If coolant mixes with oil you won't need any special tests to see it. When they mix it will look like a vanilla milk shake.
The newer coolant return systems are designed to keep the coolant level inside your radiator and engine full. When you car cools down (after running at normal temperature) it is designed to pull coolant out of the return reservoir back into the radiator. If the system gets too much pressure (usually from getting too hot) it will push coolant into the reservoir and then pull it back in as it cools. If the system has a leak then it will always pull back in more than it pushed out and the reservoir will have all coolant removed. Then the system will begin to draw in air causing the engine to eventually overheat from lack of cooling.
Your heater works from the hot coolant passing through a small "radiator" under your dash. If the coolant is low then little or not hot coolant will pass through it.
What else can I help you with?
1998 Ford Ranger heater core?
Can a bad heatercore cause antifreeze to come out overflow jug. And heat go off and on.
Why does antifreeze backup into the overflow tank?
Heat from the engine causes liquid to expand. It used to overflow onto the ground if it caused enough pressure to open the radiator cap. The overflow tanks were installed to automatically catch and return the coolant to the cooling system.
Can no antifreeze cause no heat in a vehicle?
Yes, if your vehicle is low on antifreeze, there may not be enough to fill the heater core, and you wont get any heat. When the heat stops working in your car, antifreeze/coolant should be the first thing you check.
Does antifreeze make the heat in a car work?
Yes, if your low on antifreeze, there may not be enough to fill the heater core, and you wont get any heat. If your heat is not blowing that should be the first thing you check.
Why no heat after new heater core an thermostate motor runs hot no heat?
Are you sure the thermostat is installed correctly, or is it low on antifreeze? I would check the antifreeze level first.
Why don't you have heat in a 2001 eclipse spyder?
check your antifreeze level (there should be an overflow tank with add and full lines) make sure there is antifreeze in there if there isn't add a 50/50 mix until it is full, start the engine, run for a few minutes and shut off. check the level again once it cools off. check your antifreeze level (there should be an overflow tank with add and full lines) make sure there is antifreeze in there if there isn't add a 50/50 mix until it is full, start the engine, run for a few minutes and shut off. check the level again once it cools off.
Why is there no heat at idle in a dodge van?
Lack of antifreeze or wrong mix of antifreeze and water.
1999 mercury cougar overheating new thermostat.. not leaking antifreeze only leaks through the overflow when car stops but doesnt over heat... antifreeze resvuior always seems to be under pressure?
perform a compression test to check for leaking head gasket- you may have caught this before any major damage occurs,

Will putting straight antifreeze in your rad affect your heat?
A mixture of 50% water and 50% antifreeze will transfer heat better than straight antifreeze and still protect the system from freezing up to at least 34 degrees below zero F.
How does anti freeze wear out?
Antifreeze absorbs and releases heat constantly. Over time, this causes the antifreeze to break down.
Why do you smell antifreeze through your heat?
Your heater uses somthing akin to a mini radiator to transfer heat from your engine to the cars interior. However, if you're smelling antifreeze, you have some type of leak.
