How much coolant required for a coolant swap?

 Mostly Holland. Sometimes UK.
Did a coupla jobs on the motah today including a coolant drain and refill.
Was expecting to replace 8L as I've read but only managed to drain about 5L.
Normal?

Only comment I can make, although probably unhelpful is, are you sure there is no air in the system?

Yer. Did the bleed process with heating on and on an angle etc. Will see if it needs topping up tomorrow.....
 
But if you only lost 5, then you'll only be able to add 5? There must have been something preventing the additional few litres from draining?

But yeah levels will sort themselves out with a drive :driving:
