The is a radiator leak I can see in my vehicle listed above SX model. when you pour antifreeze you can see it leaking from underneath the car. I know I need a new radiator because it is leaking a lot when you pour antifreeze into it but is that the reason why it won't stay running? And now the car won't turn on and when it does it doesn't stay running. It has a new battery and new alternator. I can see the antifreeze leaking from the radiator. I want to know is this why it won't stay running for a long period of time.
Thank you.

Good afternoon,

No, the radiator leak will not prevent the engine from running.

Did the car overheat causing the radiator to fail?

You need to replace the radiator before you can figure the reason for it stalling.
