Hi
Perhaps a dumb question but I'm assuming that to drain out / replace the antifreeze in a closed loop coolant system (on a salt water series LY6) you just remove the petcock or drain
plug from the lower side of the engine. Let the antifreeze drain out, replace the plug and then top it up again from the expansion tank?
Thanks
Ian
