coolant capacity
 
hey guys i know this thread has been posted A LOT but i still dont know what is what, i have a 2000 chevy blazer v6 that needs a radiator flush, i know how to do the flush but i cant find how much coolant to add, i have atm 2 gallons of 50/50 anti freeze but i just need to know if thats enough for a complete flush or if i need more

2 gallons should be enough

my blazer said it needed 2 gallons of coolant. (50-50) how ever it didn't take 2 gallons. Mine only needed little over 1 gallon.

That was after i started the engine and was pouring it in the radiator as needed and pouring it into the over flow container (i believe thats what it is called)

Edit: and that is after i did a flush

Yeah man if ur just draining the rad, 2 Gallons will be plenty

well to be completely honest, im one of those guys who doesnt want to just do part of it, i wanna do all of it, so i wanna get the reservoir flushed out too cause it has the red coolant in it still, so how much more would it need

the total capacity of the cooling system for a 4.3 litre v6 is 12.1 quarts (a little over 3 gallons) completley dry, so just a flush should be around 1.5 - 2 gallons.

it will take 7 qts when flushed completely. Basically the same as all the others have said. jp
