Want to flush 93 f150 cooling system with flush kit don't know which hose is which?

why would you want a diagram. The system has two radiator hose's upper and lower. One goes to the block and the other to the water pump. Now off of the pump you will have a hose going to the heater core wich is located on the passenger side of the firewall you will see two line. One comes from tyhe water pump the other returns to the block. Your question makes me think there is something else you are wanting to know. No heat? Drain radiator below the heater core lines disconnecct the two hoses then use some compressed air to blow crap out of heaster core reconnect and refill radiator
