I have recently flushed the cooling system on my Plus 8 and have refilled with coolant. I filled it up until I could see the fluid at the top of the radiator then ran the engine for 15 minutes then topped up again. It appears that the level is still adjusting and I keep topping it up since the level drops and is not visible in the top of the radiator (no fluid is seen in the expansion tank yet - the line to it is clear). So far I have added ~6 litres of fluid. There are no leaks in the system and I am sure there are no leaks of coolant into the engine since the oil seen at the dip stick is still clear and bright.
Maybe it just takes a while to get all the air out. Maybe a water wetter would have helped. Appreciate any insight from the group.
Thanks,
David
