What happens here

Place a large, suitable drain pan underneath the radiator's draincock. Open the draincock and allow all the coolant to drain out completely into the pan. Be prepared for potential spills, as hoses and connections on older vehicles might be brittle or release unexpectedly. Once drained, close the draincock.

Goal: Prevent spills and allow for radiator removal

Tools and materials

  • Drain Pan — Collecting used engine coolant
  • Gloves — Protecting hands from coolant
  • Safety Glasses — Protecting eyes from splashes
  • Old Coolant — The fluid being drained from the radiator

and i'm tall too yeah she's 5'9 and i'm 6'5 the most dreaded part of pulling an engine disconnecting the rad hose and trying not to get cooling everywhere uh i just don't know if there's a good way to do this if we pull this off up here it's gonna drip onto that we're gonna paint that so it's gonna make it harder to clean oh yeah also we are pulling the body off to paint the frame but the lift isn't wired up yet otherwise we would have pulled the body off with the engine and everything but we're gonna pull the engine out first because you gotta do what you can when you can while you can okay maybe we could do this with some precision you see what i got going on here now yeah yeah i think this might actually work you want to make bets about we're gonna be able to do this without making a mess i don't know you're pretty good at making messes yes i am success so far i didn't think it would start leaking as soon as i started loosening this i'm gonna do this wide ways because i know from experience that whenever liquid runs onto something it goes across it and then drips everywhere so we pull this off it's probably going to get on the core support and want to drip uh this way do it slowly oh yeah
