repair broken radiator overflow

[some aristo driver]

if you ever break your over flow spout then saw of spout nice and flat then tap it out with a 6mm tap. use 6mm stainless caphead bolt 18mm long or so drill center out about 4mm or 3.5mm if your worried.
drill on laithe if possible and use coolant as the stainless will heat up and harden. finally add a little thread tape to the bolt and if you want a small oring obviously 6mm. this seals the thread. re attach the line to the caphead bolt. just a pain in the ass when you leak coolant slowly. cant stand little probs like this real waste of time when you wanna do other stuff to the aristo.
