I was able to get 1.75 gallons out of the radiator and overflow this morning. The radiator drain plug is a pain in the ass. Beware it doesn’t start to flow until the plugs pops out and gives you a bath. I quickly fitted the plug back in loosely so it only came out of my plastic tubing.

fluid changed to an orangish color. Gunk must be leftovers from the block and insides of the hoses, radiator heater core, etc. There is a lot of plastic on the radiator ends.

I’m going to drop it one more time since I have the fluid on hand and call it good.
