This is how it works. The reservoir serves as a gravity trap. What I mean by that is that the weight of the water in the res forces down through the tubing and piping in the cooling chest and primes the pump. Once the pump is turned on, it just needs to pump the slug of air out of the block loops and any excess air out of the radiator, and it is bled. The pump is fed a guaranteed supply from the res, and it pumps directly up to the blocks which drain into the res. The only effort that pump has to make is to pump upwards through the blocks, and suck water through the radiator and the restricted bypass. If the bypass is opened fully, nearly no water is pulled through the radiator. If the bypass is only partially open causing enough restriction to the pumps suction, it will also pull water through the radiator to make up for the slack. The one thing that the pump needs never worry about, though, is its water supply, because even if the bypass is completely closed, water will be forced by gravity through the radiator providing an endless supply for it to pump.
Does that make sense?
