If you own a vehicle, you understand the importance of keeping its engine running smoothly. One of the common issues that can plague engines is coolant leaks. These leaks can lead to overheating and serious damage to your vehicle if not addressed promptly. Luckily, there is a solution to help prevent and repair coolant leaks – coolant stop leak.

What is Coolant Stop Leak?

Coolant stop leak is a specially formulated liquid that is designed to seal small leaks in the cooling system of a vehicle. It is a quick and cost-effective solution to prevent coolant leaks from causing further damage to your engine. Coolant stop leak typically contains ingredients that can expand and harden upon contact with air, forming a temporary seal around the leak.

How Does Coolant Stop Leak Work?

When coolant stop leak is added to the cooling system of a vehicle, it circulates with the coolant throughout the system. When it encounters a leak, the liquid is drawn towards the source of the leak by the pressure in the system. Once it reaches the leak, the stop leak reacts with the air and forms a temporary seal that can withstand the heat and pressure of the engine.
