Does anyone know where the engine block drain plug is located on the 3.4 L V6? I can find the radiator drain, but not the one on the block. I want to get all the old coolant out because I am switching to the GM extended life coolant.
I hate to tell you. But it's not a good idea to switch to the GM extended life coolant. The GM coolant does not have the electrolosis in there coolant and in that 3.4L you must have it or it will eat your head gasket alive! I would suggest you not to do that and stick with only the Toyota brand Coolant. I've learned it the hard way.
