If you have a "Leak" from the cap either the cap needs to be replaced or the top of the Radiator is damaged.

How do you Put stop leak in the radiator?

Depends, do you have a radiator cap on the radiator or is your cooling system ran from the overflow tank? if you have a cap on the radiator then the answer is pretty obvious, open the cap and pour it in. if you don't have a cap on the radiator, then you will have to remove the upper radiator hose to pour the stop leak directly in the radiator. i wouldn't try putting the stop leak in the overflow because it may not all get into the radiator thus making it less effective and could possibly even clog the lines. i had this same question and i finally found the answer so i thought i'd come back and share with you. i have a 1996 3.1 corsica and the radiator has no cap. i was thinking you could pour it in from one of the hose outlets but wasn't sure.


Where do you put stop leak in radiator if there is no radiator cap?

On most cars if they don't have a radiator cap, then you can put it in the cooling system by pouring it in through the upper radiator hose. Even if you are suppose to do this while engine is hot DO NOT because it will have the same affect as pulling the radiator cap while hot.
