Vy radiator issue

[Jesse.15]

I have a v6 vy,
A couple of days ago I noticed my radiator was dripping when I turned off the car.
So I went and put the powder stuff that stops leaks, it worked and stop the leak but now I'm always filling up my over flow bottle with water because it keeps getting empty.
And when I pull up and turn the car off a lot of hot air gets forced into my radiator and makes a boiling sound .
Doesn't anyone know what it could be?

sounds like heat gasket or inlet manifold gaskets, which are common, is the engine oil clean?

 

[Jesse.15]

Yes my oil is clean

Replace radiator cap if not new. is the engine bleed properly?

 

[Jesse.15]

I bought a new radiator cap about a 11 months ago.
It seems that my radiator has been bleed properly as no air comes out the bleeder valve

Sounds like you need a new radiator and new cap too.
Bubbling noise is probably the water in reservoir being sucked back into engine, or from engine to reservoir...?

if you have lost coolant this will happen, sounds like a new rad and cap needed
