Purchased this item to keep in the glove box in case on a coolant leak. It is small and compact thus making easy to store. I have used this type of product before with good results.

No luck this time around
So I used this stuff (different brand but same product) in the past on a few occasions, and it's had saved my butt 3 times when I had a radiator leak. I would buy it from AutoZone for a few bucks. Miracle. But I recently discovered that none of the auto zones in my area appear to carry it anymore.So I looked on Amazon and found this and decided to give it a try before spending $200 on a new radiator.Arrived quickly, the instructions say to make sure ur engine is cold and put the full tube of powder into ur antifreeze and then run the vehicle for 15 minutes. Sadly this time was not successful like in the past. Maybe it has something to do with being a different brand. Or it could also be because my radiator is too cracked for this stuff to seal it. But sadly it was not successful. I personally am still a fan of this product. As the first three times I used it, it sealed my leak on the first attempt. This is the first time that wasn't the case. So 3 out of 4 isn't bad. I would advise anyone to at least try this out first if they have a leaking radiator. It's cheap enough and I swear on it working in the past. I'm thinking this time around is because the leak is too severe so I'll be buying the radiator. But this is worth the try. It's as easy as it gets. Powder kind of looks like that Lucas candy and I don't recall the smell of it being good or bad or strong enough that it stoodout
