Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Anti Freeze for 2007 Roadster

Can someone please tell me which anti-freeze/coolant I should use for my 2007 Roadster with 6cyl 3.0 Ford engine?
It is a simple question but I have not found a convincing answer yet. Should it be IAT or OAT and what brand and how much of it should I use? Thanks in advance.
You guys came to my rescue when I could not start the car in Northern Spain about 4 years ago, turned out to be the chip had fallen out of the ignition key and someone kindly thought of that. I would probably still be there but for your help. I have since shipped the car to Tasmania and I need your help again.
