HOW TO CLEAN THE RUST & CRUD FROM THE ENGINE WITHOUT RUNNING IT THROUGH THE RADIATOR ??
Does anyone know of or made a tool that allows a garden hose to put water into the engine, and flush out the crud & rust, without using the radiator? I thought it might be a good idea to hook up the garden hose to water inlet, then run the water through the engine and let it just flow out the bottom engine hose.... anyone ever do or try that ? I'd love to hear of any tool you made that does it. Thanks for looking, Jerbo
