Last Updated on November 29, 2022 by Lily Connel

Radiator stop leak additives are used for sealing radiator leaks and preventing them from getting larger or recurring. They come in a small bottle and must be mixed with water before adding it to the radiator. Many radiator stop leaks work by forming a type of radiator sealant. On the downside, Over time, radiator stop leaks can cause significant damage to radiator systems if an excess amount is used.

Radiator stop leaks are a type of radiator additive that is used to seal small, slow leaks in car radiator systems. They generally work by preventing water from chemically interacting with radiator minerals and metals. The chemicals inside the radiator stop leak typically do not dry or harden, so the radiator will continue to work for some time before needing another dose.

Pros and Cons Of Using Radiator Stop Leak – The Table Comparison

1.A radiator stop leak is a mixture of chemicals that is added to radiator fluid to reduce the effects of a radiator leak.Not always compatible with all radiator types.
2.The most common radiator-stop leak additives contain polymers, which are designed to prevent leaks from growing by filling-in cracks and holes. This approach seems to work well, as long as radiator pressure remains high enough to force the additive into radiator leaks.Use only when a radiator shows signs of leaking.
3.The low-cost solution is Radiator Stop Leak.Requires that radiator pressure be relieved for a short time.

6.When a radiator leaks, it loses fluid and can no longer keep your engine cool. This allows for an excess of heat to build up within the system which will eventually damage it over time if left unchecked.

Finding Your Leak

The radiator is a large, metal dish that sits atop the engine. It’s designed to conduct heat away from your car and into the air by drawing in cool liquidity through its lower hose (radiator fluid) while leaving hot gases out at the top for your windscreen wipers!

There are two parts: The uppermost tube takes liquid directly off of what’s called an “upper” manifold; this way it can be cooled much more quickly than if all three tubes were lowered together. 

So close as possible below ground level – but not touching either one except just barely enough space between them where water doesn’t seep back down again when disturbed slightly shaking side-to-side). 


Stop leak is a special type of sealant designed for use in stopping the flow of oil. Engine stop leaks are pressurized with air, which helps them expand and soften the rubber on your engine’s seals so they don’t dry out over time or cause any other problems like clogging up passages under high-workload conditions.
