Review on ABN Radiator Coolant Funnel Kit - Spill-Free 🚗 Auto Coolant Flush, No-Spill Funnel Fill for Radiator System by Micah Manus

This funnel system is the best way to fill the radiator and release trapped air. A plastic tube in the center of the riser bleeds the system. With the engine cold, pour coolant into a funnel. Lift the middle handle, put the cap on, then rotate the handle so the cap holds the riser tube open, allowing liquid to flow in and air to escape through the tube. When the radiator is full, idle the engine until it reaches normal temperature. Quickly squeeze the radiator hoses until only water comes out of the breather tube. Remove the funnel and put on the radiator cap. Ready.
