Coolant flush question??

hey guys I'm trying to figure out how much coolant the block holds after draing the system and both block plugs. Or how much water you have to add ," to top it off" ,after putting in 4 gallons of coolant when doing the flush. Was trying to do a coolant flush last night and being that it was dark I didn't see that the radiator drain was open a little bit and was leaking out coolant as I was adding the water after putting in 4 gallons of Rotella ELC. I don't know how much leaked out so I'm trying to figure out what I can do. When filling up the system does all the coolant go into the block first and then start filling up the radiator and Degas bottle? I would hate to flush everything back out again( and waste all the coolant) but it looks like that's what I might have to do. I didn't hear any fluid leaking out until after I put in 4 gallons of ELC and then 1 and 1/2 gallons of water. Just trying to figure out if the majority of the coolant just went into the block and maybe I can add just some water now

Get a jug of 50/50....top it off. You can run it up to 60% concentration.

I went to go buy for more gallons of Shell Rotella ELC and of course nobody has it. I do have two gallons of Chevron Delo ELC though, would it be a bad idea to mix Shell Rotella ELC with Chevron Delo ELC?

Same stuff. No problem.

Did you remove the block drains for flush?
