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

It is normal for thermal expansion (water gets bigger when hot) to cause the coolant to go into the expansion tank when cars is hot and to be drawn back into the radiator as the engine cools

I lose about 1 gallone of Antifreeze every 130 mile and no leaks found replaced radiator cap flushed out cooling system. No antifreeze in oil and no white foam around radiator cap.?

This is an extreme amount to loose. Common sense tells you that you have a leak. The question is where is the leak? If you cannot see coolant on the pavement, then I would suspect one of two things. Either the coolant is leaking near the exhaust manifold and burning off, or you have an internal leak into the combustion chamber, ie, a blown head gasket or cracked head. Do you smell coolant? I suggest you have a compression test run asap. This will verify an internal leak. Remove the radiator cap on a cold engine, start the engine, look for air bubbles in the radiator. If you see some, you have a internal engine problem. Have this repaired immediately or you may do serious damage to this engine.

Yes if it isn't too bad, but you should leave the Radiator cap loose so radiator pressure wont forc the coolant out, and keep an eye on temp guage, and get it fixed anyway.

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.
