radiator cap might be leaking
Intake gaskets have failed.
when your engine is hot it causes the water to boil and the water and the anti freeze will come out of the overflow pipe.
On passenger side of the engine compartment, you'll see a see thru container with 3 small hoses coming out of it and a black cap. This is the coolant recovery tank and this is where you put antifreeze/coolant in.
If there is no leak visible so you can see antifreeze under the parked car, you probably have a head gasket going bad. You may have some signs of steam in your exhaust, or at least a sweet smell coming from the exhaust. You should have a compression test done on your engine. That is exactly what the overflow reservoir is for. When the engine is hot, excess coolant goes into the overflow tank, as the engine cools,it draws coolant back into the radiator.
Yes, an overflow of antifreeze or engine coolant can cause smoke and a burning smell if it spills onto hot engine components. When coolant leaks onto the engine, it can vaporize and produce smoke. Additionally, the coolant can burn, creating a sweet, acrid odor. It's important to address any coolant overflow promptly to prevent engine damage and ensure safe operation.
To the overflow tank and if the radiator has a cap,you will need to fill it with the engine cold.
In the overflow tank as well as the radiator. You should not do this while the engine is HOT!
With the hood open, on the passenger side there is the overflow container for the rad. The cap might be pressurized if the engine is hot. You add the antifreeze there.
Engine overheating will cause the anti-freeze to surge into the overflow tank. A blown head gasket will also cause the anti-freeze to surge into the overflow tank.
You really do not need to. Put the cap on and run the engine, the excess will flow into the overflow canister.
The antifreeze level in the overflow tank can drop due to several reasons, including coolant leaks in the system, evaporation over time, or a malfunctioning radiator cap that allows coolant to escape. Additionally, if the engine is overheating, it can cause the coolant to expand and push some out of the overflow. Regularly checking and maintaining the coolant level is essential to prevent engine overheating and damage.
Overfilling your antifreeze can lead to several issues, including increased pressure in the cooling system, which may cause leaks or damage to hoses and seals. Excess antifreeze can also lead to foaming, reducing its effectiveness in regulating engine temperature. Additionally, the overflow may escape through the overflow reservoir, creating a mess and potentially harming the environment. It's important to maintain the correct antifreeze level for optimal engine performance.
