2013 TOYOTA SIENNA COOLANT REPLACEMENT

Replacing the coolant. If you are doing it yourself, you are always doing it at your own risk. I'm not for using gloves in most cases, as you will see on this video, but it is recommended, as heat might be involved in this procedure. There is always room for improvement, as it seems here. Try to fit the hose when the engine is hot, before the procedure, so it expands to the diameter of the valve. If not, flame it and then push it on the valve while the tube is warm and soft. When removing the hose from the bleeder, might be easier using two hands, , as the hose might need to be turned with the valve. Turning the valve hand tight first, then removing the tube, then tightening the valve with wrench or socket now seems to be a better way to do it. At least for me.
