i need to change a cracked expansion tank and so will drain the coolant and replace it as i think that the previous owner was topping it up with neat water for awile.
Does the coolant system need to be bled via screw, or do i simply just drain it at the bottom hose or plug and refill?
Figure i will buy the premixed 50/50 stuff.
Its a 2004 Ford Fiesta 16v 1.25 LX. Ireland.
