Replace the cap with a new one. Any auto parts store will have that.
A radiator cap would not cause a leak! However, if the radiator cap is holding pressure, other weak parts could signal issues in need of attention.
Please advise where the radiator cap is located on a 1994 ford thunderbird. I have to add a stop leak product to stop antifreeze leak and I cannot locate the cap.
Cooling system leak or engine overheating and steam escaping from the radiator cap.Cooling system leak or engine overheating and steam escaping from the radiator cap.
there is a tool for the radiator to check for leaks.unscrew rad. cap and put tool cap on rad. and pump air into rad. and it will push fluid out the hole.there is your leak
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
For radiator leaks look for the following signs: The car will overheat Coolant level will frequently drop Pool of coolant or water under the car radiator Obvious leak noted from radiator on starting the car Faulty radiator cap causing the leak
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.
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.
Yes, if it is not holding pressure or is allowing a coolant leak.
try a radiator cap......or you have a head gasket leak.
Defective radiator cap? Leak in system (Pressure test)? Head gasket?
A bad radiator cap needs to be replaced as soon as possible. Fluid can leak out causing the car to overheat. Constant overheating can lead to expensive repairs. The average radiator cap costs less than $10.00, so it's worth the investment.
