Did not stop radiator leak at all
Worked Fine On A Noticable Leak!
B. Colonna✓ Verified Purchase•April 19, 2017
I bought this for my 2002 Dodge Durango which appeared to have a small leak near the bottom of the radiator. I noticed I was repeatedly adding a little coolant to keep the overflow tank measuring stick up to snuff.
I didn't notice any major spotting, but in the past week had seen some coolant which had dripped under the engine. All the hoses, etc. checked out fine, but the leak had become noticeable.
I bought one bottle and added it to the car. The bottle says to add it to the radiator, or lacking direct access through a pressurized cap to add through the overflow reservoir. I shook the bottle well. The fluid is a somewhat thick consistency. I followed the tips of a few people on-line and added most of the bottle in through the pressurized cap, then added less than a quarter of the bottle into the overflow. I capped the radiator and then ran the car for about 45 minutes. The bottle said 10-20 minutes but........
Anyway, the leak appeared to immediately stop. It has been over a week and I have not had to top off the coolant. I will update this review should anything change.
Overall, reliable product from my experience.
