    I have first drained and then refilled coolant on engine coolant reservoir, when refilling i unscrewed the air bleed bolt, everything seemed fine but a little suspicious because i’m pretty sure i spilled like a glass or more but after refilling it was full, The next morning I came to the car and I saw that there’s some coolant missing, I was like “great, I will open the lid now, let it run in maintenance mode and when theres 100% no air in it, i’ll fill up the remaining,

    However, after 10 mins of maintenance mode and 100% heat+ fan, my coolant reservoir appears full now, I didnt fill in anything, so I’m assuming theres air in the system and I have no idea how to bleed it out now considering I unscrewed bleed bold when refilling and did the maintenance mode thing... any help will be appreciated
