Replace the radiator cap with the proper OEM cap. What engine seal are you talking about. If the car is overheating, severe engine damage can occur.
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.
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.
radiator cap might be leaking
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.
A bubble sounds from the engine usually indicates that the engine is seriously overheating. It is best to turn off the engine and call a mechanic. Adding antifreeze may help, but it is likely leaking somewhere.
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.
Antifreeze can flow into the overflow tank due to the expansion of coolant as it heats up during engine operation. When the engine reaches high temperatures, pressure increases, causing excess coolant to overflow into the reservoir. Additionally, a malfunctioning radiator cap or a cooling system leak can also lead to coolant being forced into the overflow tank. When the engine cools down, some of this coolant may be drawn back into the system.
could be a bad hose, bad radiator, bad gaskets, bad Head... find out if there is antifreeze leaking, and where from. if there isn't a visible leak, check your overflow for engine oil if the overflow is black, then it's a blown head gasket, and you;r out some bucks.
