I don't know about Disco II's, but nowhere in my Disco I manual does it call for Dexcool. Dexcool is also a highly debatable coolant alternative that has had numerous complaints about it http://www.consumeraffairs.com/autom...m_dexcool.html. I personally don't like it and have seen first hand what it does to gaskets/seals when I worked in the industry. But everyone has their own opinion on this product. As for a good radiator alternative, I went with Arizona Performance Radiator. http://www.performanceradiator.com/index.phpThe design of these radiators is slightlydifferent and decreases the restriction commonly found in rover radiators, the cost is also significantly less $ as well. I have had no problems since and would also recommend the product Wetter Water to keep you down a few more degrees for when your really rompin on it off road.
