Review on 🚰 Lisle 24680 Spill-Free Funnel: Standard Adapters for Mess-Free Pouring by Christopher Millet

Required to fill an automotive cooling system. To fill the cooling system in vehicles without an expansion tank, I have always been able to use the following procedure. After repair, fill the cooling system with a funnel and nozzles, leave the funnel 1/4 full with coolant. manually. Start engine and maintain 1/4 coolant level in funnel. After the car warms up to operating temperature, make sure there are no large bubbles coming out of the coolant, massage the upper radiator hose to make sure there is no air in the system. Stop engine and allow to cool to ambient temperature. Temperature, make sure the coolant stays on top as the coolant will be compressed back into the radiator. After the engine has cooled to ambient temperature, remove the funnel and install the radiator cap. This removes the greatest amount of air from the cooling system without the need for depressurization.
