How many liters does one bottle treat?

I’m not sure, all that I can say is that you put the full bottle in and let it run through the system. I used it on my 2.0L Mercedes and it cured what was quite a bad leak

Do i add this when engine is hot or warm or cold?

Add when cold then turn engine on to circulate and get hot around 15-20 mins by then the leak should have stopped.ps wait till your water is on the low mark to allow for the rad weld fluid.

How easy is it to use.
