Why is it that rads are always a problem. Back in 2008 I had a couple of replacements for a new Caterham i had at the time, i eventually bought a Pro Alloy rad and never looked back. My 2011 Plus 4 radiator expired at 3 years old, usual issue, leakage at the header tank / core crimped joint. Installed the Mulfab kit, problem solved, still going strong. Pro Alloy manufacture some great ali rads etc. My pal has just took delivery of an ali rad for his C-Type Jaguar, it too nice to install in the car.
