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.
YOUR WASTING PEPPER. It won't work. Replace the radiator.
if it is leaking from the radiator you can crack an egg and put it in the radiator and it will solve your problem
It depends - if the leak is small, just put a bottle of Barr's stop leak in the radiator - make sure you follow the directions. It works great on small leaks.
A good stop leak product for a radiator is the Bar's line of stop leak. It comes in an easy to pour bottle which seeks out leaks and seals them in minutes.
change th radiator
stop leak
I have used radiator stop leak before in my 1996 Olds Achieva SC with the V6. I put it directly into the coolant resovor. It went in fine for me. This did not give me much help though. I would not recommend using stop leak. It will clog your heater core and then you will have more than the radiator as your problem. Fine a new radiator and replace it that is the best advidce i can give you.
Barr's Stop Leak is a brand of radiator repair chemicals. Barr's Stop Leak is poured in the radiator and the engine is run at an idle for a few minutes. It will repair small leaks like those that happen if a rock strikes the radiator.
There should be no problem... I have put in my car in a time of emergency... and it was fine until i could take it to the dealership...
A raw egg in to the tank.
You dont. -Mechanic
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.
