Review on 🚗 ABN Automotive Coolant Flush Machine: Ultimate Air and Water Combo Backflush Gun – Versatile Multi-Size Nozzles for 19-40mm Hoses by Darren Munajj

ordinary garden hose will NOT fit the water inlet. You need a plug-in or quick hose adapter! It doesn't come with it and the product description doesn't say you need it! Also, there is no check valve at the water inlet to prevent air pressure from entering the water inlet hose! The air/flushing pressure entering the radiator is never greater than the water supply pressure! THAT IS TRASH!
