AlumAseal Radiator Stop Leak Powder is rated 3.0 out of 5 by 4.
Rated 4 out of 5 by from Slow Leak I have a very small leak and didn't want some big bill replacing something just yet. Only leaks while driving.

Rated 2 out of 5 by from works in a pinch (when needed) it works to seal/stops leaks without clogging up other components

Rated 5 out of 5 by from Sealed my radiator the first try Every time I parked I had coolant leaking from the radiator. Thought I would give this product a try before having to spend any more money on this vehicle. After putting the sealer in the cooling system and heating up the engine for about 15 minutes, the leak was gone. So glad it worked for me.

Rated 1 out of 5 by from Not worth the money Product caused more damage than it fixed. Spend the extra money and time tracking down the K-Seal. The cheap flake products like this one clog the thermostat causing overheating and more work to be needed.
