can anyone help i had a pipe com off the engine whilst riding to work so called rac and they refitted pipe and topped up with water so now i want to drain system and refill completely with new coolent. my question is how much antifreeze do i need to put in and how much water? as the manual i have said the cooling system only takes 1ltr of coolent does that mean i have to use 1ltr of water as well? as this does say its a 1.1 cooling system
