Here's what I was told. It doesn't matter really. The blue stuff was used to keep people from getting it called fused with something else and putting the wrong stuff in the radiator. The I was told that people started putting window washer in there.  So I was told they use green now. 
That's what my previous (and previous for good reason) told me to use now. He flushed it (dunno what color it was) and filled it with green. 

All this talk of numbers and stuff has got me lost. 

Can someone please just tell me if green is okay and what to use if not. 

Thanks 
Roman
