What does it mean when your car is overheating and smoking and the antifreeze is draining out of your radiator but you can not find a leak anywhere?
Kevinhenry
It means the leak is small.
A large leak will drip, while a small leak will only leak when the system is pressurized from the heat. The small leaks spray out and make steam, which looks like smoke.
If you weren't losing coolant, I'd say the smoke was from either the exhaust manifold or from a bad valve train shooting exhaust back out the carburetor. Most new cars don't have carburetors.
As a side note, you might be able to find small coolant leaks by following the supple black hoses and looking for things that have been sprayed by them. If it's not obvious, follow the steam to its source. Chances are, you'll either find a hose with a small leak or it's coming out of a crack in the engine itself. Sometimes, gaskets that separate the oil and coolant can break down and coolant will get in the oil. It then can leak out the oil gaskets much faster and easier than oil can, because it water/antifreeze mixtures evaporate and pressurize so readily compared to oil.

Why is a 1994 Honda Accord LS overheating and leaking antifreeze?
ah.......radiator??
How does antifreeze keep the water in your radiator from freezing and overheating?
It changes the freezing and boiling point.
Your husband flushed out the radiator and filled up with new antifreeze and it is now overheating and never did that before what do you do now Help?
Is it at the correct fill level ? If the radiator is old it is possible some corrosion has blocked up soemwhere and the radiator may need anther draining and flush through with water till it clears out.
Why so people put antifreeze in car radiators?
antifreeze keeps your car from overheating, it flows thru your radiator hose, without it your motor would blow
What could be wrong if your car is overheating you have already checked water pump and thermostat and there are no leaks anywhere?
The radiator may be plugged. Take it to a radiator shop.
Antifreeze in a 2001 celica gt if it gets low but there is no overheating or leaking what is wrong?
It could be caused by a defective pressure cap on the radiator cooling system.
Why do you uses antifreeze?
Anti-freeze disburses heat produced by the engine (via radiator), thus preventing engine from overheating and allowing it to properly function.
Why does your 1990 blazer keep overheating you replaced the radiator thermostat and water pump and you have no leaks except from over flow when its hot and no antifreeze in the oil?
Bad head gasket or... Crack in exhaust port in head. Check exhaust for presence of antifreeze smell or exhaust gas in radiator.
How do you add antifreeze to a car?
Open the radiator cap when the engine is cool, check the radiator's fluid level, and add appropriately. NEVER OPEN A RADIATOR CAP WHEN THE ENGINE IS HOT OR OVERHEATING. Check your car's owner's manual for specific details.
What is a radiotor used for in a car?
The radiator is used to cool down the coolant (water plus antifreeze etc) which in turn is used to circulate the engine and prevent it overheating.
How do you find overheating on a 1988 motorhome 460 engine?
There are several things to check for overheating. check all belts,,hoses,,and the recovery tank. If the recovery tank is not in good condition,it will not recover antifreeze when engine warms up and transfer it back to the radiator. Next, and the most common problem, is a radiator that is partially blocked internally. Try a good commercial radiator flush,,follow the directions exactly for best results. If it still overheats, have the radiator serviced by a good radiator shop. Make sure you are using a good quality antifreeze/water mix. DO NOT use just water. Antifreeze raises the boiling point of the cooling system,,it is supposed to do that. Remember,,HEAT is the main killer of engines and transmissions. It is worth the money spent on keeping the engine from overheating.
Why is antifreeze necessary?
To keep your engine from overheating the coolant runs from the radiator through the hoses into the block and back through the hoses into the radiator where it gets cooled by the fan and the air and starts the process all over again.
