Hi,Clive ,Ive run a Burlington for the last 15 years . I originley used a re-cored Spitfire radiator but this struggled to cope.I then tried a custom alloy rad 15x15 x2 inchs with aFord Mondao electric fan,this has worked very well on my travels around europe. Start the car up and see if the top & bottom hoses get hot ,check that the rad is hot (top & bottom).If not may be a blocked rad or stuck thermostat. Ive noticed you may have Haydens original design rad grill, this may restrict the amount of air entering the rad. I suggest you remove it and see if this helps and KEEP HANDS AWAY FROM FAN!!! ATB Ray
