Admittedly the best solution is to find the problem and putting in 
aluminium radiator may be using a hammer to knock in tin tack.  But 
then MGBs do overheat given hot climates and big hills and thrashing 
- so who knows (only the Shadow!).  I  wonder if it is an internal 
collapsed wall of a rubber hose, - or maybe the water has been put in 
upside down??

I believe that the efficiency of aluminium rads has nothing to do 
with thermal co-efficiency but because aluminium is stronger and one 
can use long sided rectangular tubes giving far more surface area and 
thus better cooling.  Anyone know about this?
