Ahh right. I know they dont take a lot. Helps we've got two toyotas so can always pinch my parents stuff lol. And yeah. Drop the thermostat out, drain all coolant out, fill system with water and let it circulate. Drain off fully, refit thermostat then fill system with the red. Thats how I do it anyway. And haha, I didnt notice it at first lol/ D
