this is kind of a dumb question i think. this past summer i was doing some work on my TD. i kept having coolant leaks so i would just put water in the radiator instead of wasting more coolant. now with winter coming i would like to replace the water with antifreeze now that i've fixed the leaks. is there a good way to get the water out of the engine so i can put in antifreeze so the block wont crack this winter while the truck is sitting?
