I don't know.
The idea of a bypass hose is rather old-fashioned and mostly these were deleted decades ago due to the fact they slow the engine warm-up.
These days the bypass, if required is either an internal port or if the heater matrix is permanently supplied with coolant it performs the function of a bypass.
Most modern engines are fitted with a degassing system and that is perhaps what you are thinking of. Earlier types often circulated a small amount of coolant from under the thermostat to prevent gas accumulation interfering with the thermostat operation while some later types were connected above the thermostat and sometimes the radiator.

SOURCE: How do you replace the water pump on a 1992 Mazda
Hi:
The water pump is driven by the timing belt, which is on the passenger side of your engine. You would need to remvoe all belts, and then the timing belt cover, and the timing belt to change your water pump.

I had the same problem a couple of years ago. It is actually located on the bottom of the engine. I have no clue why. They are usually located on the top for easy access. Follow the hose coming from the bottom of the radiator to the engine block.
