Hi All, i flushed and changed the coolant in my 916 today, pretty simple job really, but the Haynes manual says the system should take 3.5 Litres and mine only spewed out 2.7L and took about the same back in, i flushed and bled as per instructions, am i missing something?...BTW i was toying with changing my hoses for Posh silicon items but the existing OE ones are sound so they're staying put.
