Where to put engine coolant expansion tank

I need to move my coolant expansion tank, there's just no room to have it mounted next to the engine. The spot I'm thinking of, is on the other side of a plywood wall putting it under a counter.

My question is this, does the expansion tank need to be higher than the engine's heat exchanger? I'm wondering if siphoning would be an issue. ie Would the coolant siphon into the expansion tank and just fill it up, lowering the coolant in the heat exchanger. What goes on inside that heat exchanger cap (radiator cap)? Can it prevent siphoning? If so, then how does it draw the coolant back?

My guess is that it needs to be higher than the heat exchanger, can someone please tell me otherwise???
