What's the Lexus gx470 coolant capacity?

The Lexus GX470 has a coolant capacity of 6.8 quarts. It's going to use a so called "Red" antifreeze/Coolant to top off or do a refill with, which is ethylene glycol based and incompatible with borate and silicate based coolants.. Typical cost for a 32oz jug of Valvoline brand for thiS-TYPE will run around $20 at Walmart. If You're wondering how to drain Your radiator, look down on the bottom of the radiator on the driver's side: You should see a small yellow drain plug there which You simply turn counter-clockwise to losen and then pull out. You can hook up a piece of tubing to the drain tube there if You want to direct the coolant away from where Your Lexus IS parked.
