A coolant stop leak is a product used to seal minor leaks in a vehicle’s cooling system. It can be a temporary or permanent solution, depending on the severity of the leak and the type of stop leak used. Coolant stop leaks are available in liquid, powder, and tablet form, and they can be added to the coolant reservoir or directly to the radiator.
Coolant stop leaks can be an effective way to stop small leaks and prevent them from becoming larger problems. They can also help to improve the performance of the cooling system and extend the life of the radiator and other components. However, it is important to note that coolant stop leaks should not be used as a permanent solution to a major leak. If a leak is severe, it is important to have it repaired by a qualified mechanic.
