I used it, it foamed like a pet in the army. flush the cooling system for 2,500 and it foams a little further. every now and then I open the radiator, the foam comes out, I add the cooling mixture. So get excited. Yes, the heater started to heat up a bit, but only after a service flush did the humac leak out. Now the question is whether I should have just let it rinse without the lubricant, or just replace the radiator. the replacement price would probably not be much higher.
I guess it's cleared up a bit
it foams like a cow

Container content is for 10L of cooling mixture - I recommend to keep this or rather buy 2 for higher concentration in the cooling system, you will not notice the difference when saving the product. Concentrations must be maintained for quality cleanup, recommended.
I recommend
Cleans well
Packing only for 10L of coolant for new cars, 2 - 3 bottles must be bought

The instructions in Czech, which Liqui Moly pastes on the can, were re-tagged with a barcode by an intelligent Alza employee. It's not the first time
Product works as expected
No instructions in English on the can

Verified purchase - review from a price comparison website
Unfortunately, alza does not include the information "Protect from frost during storage" in the description and the goods are delivered in winter to the alzabox, which I think is not heated. So it violates the manufacturer's storage rules. This information should be provided with the product so that you can choose to pick it up at a branch or not leave it in the alzabox overnight.
I can't judge the functionality, used as a precaution, but it is a quality brand, so I believe it works.
Look out! Alza does not have the information from the product sheet in the description - "Protect from frost during storage", which is quite a problem in winter
