Cooling issues

[rotaryheaven]

Right, I\'ve been have cooling issues on my fc so I\'ve decided on replacing the complete cooling system, ive just brought a 53mm koyo rad, do luck fc3s coolant hoses, arc low temp thermostat, I\'m looking to renew the other water pipes around the engine bay but I don\'t know the size of the pipes, would anyone know what size the other hoses are? I\'m not being lazy by the way, I just don\'t want to risk breaking any hoses and having to take the car of the road . Is there anything else I could get to improve the coolant system? I\'m trying to get all the parts for next weekend so any help with this would be great.
