Five failed radiators in less than six years on my Caterham 420R. Will number six do any better?!

I'm back from a trip to Ireland so this is just a quick chat about what's coming next, and fitting the cars 6th radiator today. Yes, you read that right, radiator number 6. It's not even six years old and has only done a fraction over 6000 miles. Some rads are only lasting 500 miles. What is going on?! Chapters: 0:00 Ireland trip 0:45 Tyres 3:49 Radiators
