Scotty, I see what you are talking about with the hoses and heater core. My first concern is now that I am in MN winter, would I be at risk of freezing my block by replacing the amount of coolant in the heater core and attached hoses with pure water vs 50/50 mix?
Second, when you say "flush, refill hoses, and get back on engine quickly" are you just getting the fact that, after flushing the heater core, I don't want to let water drain out of the hoses because it will just cause more air to get back in the system?
Thanks man.
