I have a 1989 Mini Thirty and I'm currently redoing the heater system.
I have purchased 1/2" heater hose along with a heater valve for the cylinder head rather than the plastic valve between the pipework.
Is it suitable to use 1/2" pipework with this arrangement rather than the 5/8" hoses as it came out the factory?
Feel a little bit stupid asking the question but better to be safe than sorry I guess!
Thanks in advance,
