How did you remove and attach siphoned hose? Very hard to get toHaving done this today thought I would provide my 2 cents on what I learnt.
Service manual does state 2.5l but despite my best efforts I managed only 2.2l - 2.3l. It states to leave upright when filling but does not say what position to drain but obviously, it's more effective lent on the side stand.
Removing the water pump drain bolt, air bleed bolt and reserve tank siphon hose will allow it to fully drain properly. Once drained I poured half a litre of water in to wash away the dregs. Replenishing the system used almost exactly 2l and the reserve tank a further ~250ml.
I found it difficult to locate the siphon hose initially but it's actually very easy. At the bottom of the reserve tank, left side, probably hidden behind several other hoses. Once pushed aside you should see it clearly. Images below for reference. I used Putoline Ultracool 12 coolant, I also have 700ml left if anyone UK based wants it to save buying a third bottle. Pay postage and it's yours! 👍🏼
