Mocki ok, how it works:
Top up tank to fill mark, when engine cold.......
Engine gets hot, coolant expands, builds up pressure with temp, and opens header tank pressure cap forcing coolant into the top up tank........
Engine cools down when parked, coolant contracts, pressure turns to vacuum, and coolant is sucked back from top up tank to header tank, returning top up tank to fill level from its over full state when hot.....
So, if the pipe between is split or leaking, it would be pushed out of the header tank and out of the split pipe onto the zorst, not into the top up tank, and when the engine cooled down, the header tank would be not full.......
However, if you overfill the top up tank ( fill it when cold with hose pipe) it will push excess out of the breather holes in top of the top up tank, onto the zorst, and find its correct level.....
