MANNOL 9966 Radiator Leak Stop COOLANT Leak Repair for Cooling System of Internal Combustion Engines (ICE) and Interior Heating System 325 ML Imported from Germany

A lot of people say it does not work. I use a chevy 2007 and it worked great for me. I had to buy this 3 times.1st time, full bottle used in 1 go, worked amazing. Went to mechanic, got a radiator flush and the leak came back up.2nd time, used bottle 3 times cuz it was not sealing, did not work and leak continued. No mechanic involved3rd time, got the bottle, used the full bottle in one go and it worked again. No mechanic involvedMoral of story, use the entire content of the bottle in 1 go. It will work, if it doesn't, the leak is bigger than imagined.

I have been seeing leakage in my radiator and coolant comes on the intercooler drop by drop so then I decided to use this mannol and magic happen I pour the it with coolant and drove my car for 20-30km and some level drop after that I again add some coolant and add more mannol next day morning my coolant level is same as last night and leakage stop thanks to mannol best product I ever used and safe for use in any kind of coolant and use it with the coolant _my car polo tdi 2017
