How many ml fluid in 240mm rad?

Im about to clean the radiator for my build .

Its a hardware labs gts 240 rad, and dont want to mix up too much Mayhems Blitz Cleaning Pro Part 1, so any one know about how many ml fluid will fit in this thing? Guess I could pour tap water in and then measure it, but a bit easier if anyone already know.

 

It should say in the specs. Otherwise, it’s a guessing game.

 

Fill it up and measure it has to be the easiest way.

Im planning on doing that exact thing to that exact rad this weekend so can let you know

 

well i guessed and i guessed correct!
the part 1 solution is 1:3, 1 part solution to 3 part water, so I divided with 4 and came op with about 65ml solution to 185ml water and that amount is just about right + a little spillage.
