How do you get all the coolant out when changing anitfreeze

I changed out my antifreeze the other day but according to the manual the capacity of the system is 16 quarts. I was only able to get about 8 quarts out and that included starting the engine for a few minutes to see if the water pump would push more into the radiator to drain out. I waited for about 45 min. after opening the radiator drain plug until there was nothing else dripping out. When refilling the system I was also only able to pour in about 2 gal. of 50/50 coolant. :wtf2:

Lots of coolant still sits in the engine and the heater box. I usually remove the rad cap and the coolant overflow lid and drain the rad in that order. I don't recommend running the engine without proper coolant in there though, the water pump uses coolant to lubricate the bearings.

CoronaRaptor that is pretty much the same thing i did. Removed all I could out of the radiator and siphoned out what was in the overflow tank. after topping the radiator and overflow tank to proper levels, I drove about 5 miles and then let the engine cool and rechecked the level in the overflow tank. I just had to add a little to get to the proper mark.

haven't looked yet so I cant say exactly but most ford blocks have a block drain via pipe plug on either side just above oil pan should get all or most of the coolant out. Usually install drains in mine after my first coolant change

Well it is a pain but first drain all you can then fill with water--repeat a couple of times after driving for 5 minutes or so with the engine at operating temp them add flush. Drain and fill a couple more times then use distilled water to fill and drain till soap bubbles quit coming out of the line when draining, then I fill with Cat coolant that is premixed.

Like I said it is a pain but have been doing it this way for many years.

Thanks Boss, yes it does take more work but worth it in the end I am sure.

maybe taking the vehicle to one of those fast oil change places, I think they suck all the fluid out. But I cant confirm but I do know that's how they do it for trans oil changes.
