ChickenNug

Hello! I want to change the coolant on my GS 350. I am trying to figure out how much new coolant I need to purchase in order to fill after draining from the engine block and the radiator.
Some videos suggest I need 3 gallons to do this, but some threads suggest that a single change can only get 40-60% of the fluid out which is around 4-6 quarts.

Any suggestion? Thanks!

It's easier to return an extra unused bottle of coolant than having to go to the store in the middle of your coolant job.
