Using Prestone flush kit to flush cooling system

Have you used this yellow plastic kit to flush your cooling system before vacuum filling it? If so, which hose the heater hose, perhaps should be cut to install the hose adapter? I intend to remove the lower hose to drain the old coolant into a suitable container for safe disposal and perform a final flush with distilled water just to be sure. Specialists, correct me if I am doing something incorrectly!

Everything should always be kept to OEM specifications; nothing should be trimmed or altered inside the engine compartment. See Chris Fix’s YouTube video on radiator flushing if you want the cooling system in your car or truck to be clean. When it comes to assisting you with DIY car repairs in your driveway, he is the greatest.
