For small leaks, a stop leak product may be a temporary solution to prevent the leak from getting worse and buy you some time to get your car to a repair shop. However, it is important to note that stop leak products are not a permanent fix and should only be used as a temporary measure.
For larger leaks or leaks in critical areas of the radiator, a stop leak product is unlikely to be effective and you should take your car to a repair shop as soon as possible to have the radiator repaired or replaced.
When using a stop leak product, it is important to follow the directions on the product label carefully and to avoid using excessive amounts, as this can cause damage to the radiator or other components of the cooling system.
If you are unsure about whether or not to use a stop leak product, it is best to consult with a qualified mechanic.
