What is Stop Leak for Radiator?

Before diving into the buying guide, let’s understand what stop leak for radiators is. It is a liquid or powder solution that helps seal small leaks in the radiator and prevents further leakage. It works by circulating through the cooling system and filling in any gaps or cracks in the radiator, water pump, or hoses.

There are two main types of stop leak for radiators: liquid and powder. Liquid stop leaks are easier to use as they can be poured directly into the radiator.

Stop leak for radiators comes at different price points depending on its brand and effectiveness. Consider your budget but also keep in mind that cheaper options may not provide long-lasting results.
