    Run the engine on the muffs to warm up and the special blend of fuel though the system. Once done drain the block and introduce anti-freeze though the muffs until it is seen coming out of the exhaust. Then followed by the disclaimer to have the dealer do it so if something is done wrong you can blame them.
    I had asked if there was a benefit to switch to a Closed System he said no not as far as winterizing the engine goes.
    ah the first time you left out, the part I put in bold print...if you drain the block...that method will work because it eliminates the unknown factor of the thermostat opening or not. Its still easier in my opinion to manually drain first, poke holes, and replace the plugs then fill with AF via the hoses.

      I'm sorry I thought I had typed that. To many thought in my head.
