Circulate Antifreeze Through Pump

What happens here

With the pump protector bottle attached, turn the pressure washer's spray nozzle to the 'ON' position (as if you were about to spray). Then, firmly pull the engine's starter cord a few times. This action will prime the pump and draw the antifreeze from the bottle, circulating it through the pump and all its internal components, including the thermal relief valve. Continue pulling the cord until you observe the distinctive pink-colored antifreeze visibly exiting the system, confirming that the protective fluid has circulated thoroughly.

Goal: Turn the pressure washer nozzle to 'ON' and pull the engine's starter cord repeatedly until pink antifreeze exits the system, indicating complete circulation.
